Size is not paramount - but still an advantage

Up to 1.8 kW in a 19½-inch chassis

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

Use the DP-M Series as a standalone unit or integrate it into your rack setup. Units up to 1.8 kW are available in a compact 19-inch half-width enclosure with 1U. Two of these units can be mounted side by side in a separately available rack insert. For full-width units in 2U and 3U configurations, rack-mounting accessories are included.

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. With 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 capped at the sum of the modules' rated powers. The HE specification covers only the equipment heights; therefore, 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 recovery, a properly designed protection concept is required.

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 will 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 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 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 Reverser
The AP6 allows the output polarity to be switched either on the module itself or via an external control loop. Before each polarity change, interrupt the load current—for example, by turning off the output or using an existing interlock function. Current-free switching is not automatically guaranteed. The electrical and mechanical design is tailored to the power supply and the application.

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)

RS232 and RS485 with Modbus RTU are standard features. The documented protocol allows you to set and retrieve output values and makes it easier to develop your own control and test programs.

LAN connection (optional)

The optional D4 LAN interface allows you to expand the digital connectivity of your network infrastructure. The desired configuration is specified when placing your order.

Remote Meter Input (Standard for rated currents of 50 A or higher)

DP-M models with a rated current of 50 A or higher come standard with a remote sensing input to compensate for line losses of up to 2 V. The sense leads measure the voltage directly at the load, allowing the power supply to compensate for the voltage drop in the load lines. Remote sensing is not provided in master/slave parallel operation.

The four-pin connector on the rear panel carries Output+, Sense+, Sense-, and Output-. For remote sensing, Sense+ and Sense- are connected to the positive and negative terminals of the load, respectively. For operation without remote sensing, the dummy plug must be inserted. The dummy plug, which is typically included, connects Output+ to Sense+ and Sense- to Output-. Devices with a remote sensing input may only be operated if Sense+ and Sense- are correctly connected to the load or if the specified jumpers are installed.

Interlock Loop A1 (in the optional analog package)

The potential-free interlock loop A1 is included in the optional analog package. An open circuit blocks the output, while a closed loop re-enables an output that was previously activated on the device. This allows, for example, an external enable condition of the test setup to be taken into account.

Analog Voltage Control U (in the optional analog package)

You specify the output voltage analogically via the two-pole control input on the system bus connector. The available options are 0 … 10 V (U1), 0 … 5 V (U2), or 4 … 20 mA (U3), depending on the signal standard selected for the entire package.

Analog Current Control I (in the optional analog package)

You specify the output current analogically via the two-pole control input on the system bus connector. The 0 … 10 V (L1), 0 … 5 V (L2), or 4 … 20 mA (L3) versions correspond to the signal standard selected for the package.

Analog actual voltage value U (in the optional analog package)

The two-pole feedback output on the system bus connector transmits the actual value of the output voltage. Depending on the signal standard of the analog package, the output is 0 … 10 V (F1), 0 … 5 V (F2), or 4 … 20 mA (F3).

Analog Current Actual Value I (in the optional analog package)

The two-pole feedback output on the system bus connector transmits the actual value of the output current. Depending on the signal standard of the analog package, the output is 0 … 10 V (G1), 0 … 5 V (G2), or 4 … 20 mA (G3).
