Size is not paramount - but still an advantage

Up to 1.8kW in a 19″ 1/2 cabinet – no problem

Symbol image shows a DP30-60M high performance power supply, please refer to the data sheet for the size of the selected model.

Sophisticated technology and high-quality, choice components enable high performance in a compact cabinet. Up to 1.8kW of power is delivered by the DP-M high-performance power supplies series from a 19″ 1U 1/2-width cabinet, which allows two units to be mounted side by side in a 1U rack. In addition, high-performance power supplies of the DP-M series can be used in all cabinet sizes both rack-mounted and free-standing – the suitable mounting accessories for rack mounting are supplied free of charge with all units in 2U and 3U cabinets. Suitable mounting accessories for two 19″ 1U 1/2 units in one rack can be ordered separately.

Less than and including 1.8kW 19″ 1HE 1/2 width cabinet
Greater than 1.8kW and up to 12kW 19″ 2U cabinet
Greater than 12kW 19″ 3U cabinet

Attention: Cabinet size may differ for certain models, e.g. 2kV models, please refer to the data sheet.

Greater Performance in Parallel Operation

If a single power supply unit is not sufficient, expand your DC power supply with a master/slave parallel system consisting of DP-M full-width units equipped with the appropriate parallel components. The voltage range remains the same, while the available current increases with the number of modules. The following example systems range from 20 V to 2,000 V and each provide more current than a single standard model in the series can deliver at the specified voltage.

For each voltage range shown, the examples use six units of the standard model with the highest rated current. The maximum output voltage, total current, and calculated system power are specified. One unit is configured as the master, and the other five as slaves. For the DP-M series, this role is set on the unit itself; separate master and slave versions are not required. The examples refer exclusively to full-width devices.

* System power is calculated based on the listed voltage and current limits and is limited to the sum of the modules' rated powers. The HE specification refers only to the height of the units. Additional space for cooling, cabling, and protective components must be planned for separately.

We tailor the number of modules, system configuration, power connection, and protective circuitry to your test setup. In parallel operation, an external analog control is not available on either the master or the slaves. For loads with energy feedback, a properly designed protection concept is required. Parallel operation does not turn the power supply into an energy sink.

Compatible with external expansion modules from the AP Series

Expand your DP-M series high-performance power supplies with additional functions – even after purchase.

Image shows a DP6H-12M high-performance power supply with AP8 module, please refer to the data sheet for the size of your selected model.

With the external AP modules, you can adapt the DP-M Series to meet the additional requirements of your test setup. The expansion interface allows you to add suitable functions even after purchase. We tailor the available modules, electrical configuration, and mechanical design to your power supply and the connected load before you place your order.

Five expansion modules of the AP series are currently available:

Model AP9: Application-Specific Reverse Current and Reverse Voltage Protection
With the AP9, you can tailor the additional protection to demanding inductive or capacitive loads. The module is custom-manufactured to order for the expected currents, voltages, and energy levels. Options include a combined protection circuit against high reverse currents and reverse voltages—particularly reverse-polarity transients—or a design as an active braking chopper to convert regenerated energy into heat. The design specifications and permissible duty cycles will be agreed upon to suit your test setup.

The output rectifier stage already provides basic protection against same-polarity reverse currents within the device's permissible limits. AP9 supplements this built-in protection. The power supply is not an energy sink with unlimited load capacity. Reverse current, reverse voltage, and stored load energy determine the required design.

Model AP8: Additional output-side EMC filter with a capacitance of
To meet increased demands on your load’s power supply, the AP8 combines a three-stage EMC filter with additional output capacitance. The module helps reduce conducted interference and stabilizes the power supply to demanding loads. The design takes into account the power supply unit, the load, and the desired dynamic response.

Model AP7: Additional EMC filter on the input side
The AP7 supplements the existing power supply filtering with a three-stage EMC filter. It is designed for applications with increased requirements for reducing conducted interference on the power supply side. The single- or three-phase version and current-carrying capacity are selected to match the power supply unit.

Model AP6: Polarity changer
The polarity changer module extends the power supply unit with the option to rotate the output polarity during operation. This can be controlled either directly via the power supply unit (digital connections - Modbus RTU), or the module (analogue input 5V, mechanical switch on the front panel). Reversing the polarity interrupts the power supply to the load for no longer than 2 seconds.

Model AP5: Mechanical Isolation of the Load from the Power Supply
In safety-critical applications, mechanical isolation between the power supply and the load or test bench may be required. The AP5 module enables direct mechanical isolation of the power supply from the connected load, thereby providing an additional level of safety for such applications.

Versatile verso

Integrate the DP-M Series into your test stand via the standard RS232 and RS485 interfaces using Modbus RTU, or optionally via LAN. A complete I/O package is available for analog control systems: voltage and current setpoints, both actual value outputs, and the A1 interlock loop. You can select either 0 … 5 V, 0 … 10 V, or 4 … 20 mA for all four analog functions collectively. The functions U, L, F, and G described below are offered as a package together with A1, not as individually selectable components.

Digital interface RS232 & RS485 (standard)

Equipped as standard with RS232 and RS485 connections and full support for the Modbus RTU protocol, high-performance power supplies of the DP-M series allow both integration into the existing infrastructure and the development of a new one. The open Modbus RTU protocol allows customised control solutions to be implemented quickly and effectively, so that nothing stands in the way of automation.

LAN connection (optional)

The high-performance power supply unit of the DP-M series has RS232 and RS485 interfaces with Modbus-RTU support as standard. This makes it easy and convenient to integrate the power supply unit into almost any existing infrastructure. On request, the power supply unit can also be upgraded with LAN port with option D4.

Remote-sensing input (standard)

The remote-sensing input is installed as standard in all power supply units of the DP-M series and allows to compensate for line losses between the power supply unit and the load. The power supply unit can compensate for losses of up to 2V by measuring the voltage at the load and automatically counteracting it. This function is particularly useful for high currents of over 100A and/or particularly long cables with small diameters. Furthermore, the remote-sensing input is necessary for connecting modules of the AP series.

Interlock input (optional)

By adding the interlock function to the power supply unit, the output of the power supply unit can be blocked under certain conditions instantly. An example application would be to block the output of the power supply unit when the protective cover of a machine connected to the power supply unit is open. Furthermore, the interlock input can be used to switch the output of the power supply unit on or off remotely by first switching the output on manually and then releasing or blocking it via the interlock signal. For DP-M series high-performance power supply units, the interlock input is designed as a floating loop which blocks the output of the power supply unit in the event of an interruption – the option designation is A1.

Analogue external remote control of the output voltage (optional)

If your application requires an analogue connection and remote control of the output voltage of the power supply unit, an analogue control input (2-pin) can be realised with option U via the system bus connector. The standards 0 ... 10V (U1), 0 ... 5V (U2) and 4 ... 20mA (U3) are available for the control.

Analogue external remote control of the output current (optional)

Option L adds a control input (2-pin) to the power supply unit via the system bus connector which enables the analogue external remote control of the output current of the power supply unit. The standards 0 ... 10V (L1), 0 ... 5V (L2) and 4 ... 20mA (L3) are available for the control.

Analogue actual value signal Output voltage (optional)

Many applications require not only the option to set analogue output values, but also feedback about the current actual values. Option F expands the power supply unit by a feedback output (2-pin) via the system bus connector, which transmits the current actual value of the output voltage of the power supply unit. The standards 0 ... 10V (F1), 0 ... 5V (F2) and 4 ... 20mA (F3) are available.

Analogue actual value signal output current (optional)

Option G expands the power supply unit by a feedback output (2-pin) via the system bus connector, which transmits the current actual value of the output current of the power supply unit. The standards 0 ... 10V (G1), 0 ... 5V (G2) and 4 ... 20mA (G3) are available.
