The DP-D Gen2 series expanded upon the previous DP-D series by adding digital control and a clear display of setpoint and actual values. Units with the [Y] option at that time also featured a 4.3-inch color display. This allowed users to program time-dependent voltage and current waveforms—including rise times—for applications such as recurring square-wave waveforms, and to monitor the actual values over time. The [Y] option also added a LAN port and a USB host port to the front panel.
The high-performance digital power supplies of the DP-D Gen2 series were developed for power-intensive applications in laboratories and industry. Earlier models offered power ratings up to the megawatt range and, depending on the configuration, featured analog or digital remote control as well as “ cabinet ” for freestanding operation or rack mounting. This series is no longer in production. The following technical information is provided as a reference for existing units. The documentation for the specific model is authoritative for their operation.
Additional options
The following is a brief description of the possible additional options for digital high-performance power supply units of the DP-D Gen2 series. A detailed description can be found in the data sheet of the series. If you have any questions, please contact our support during our opening hours via live chat or by e-mail and we will be happy to help you.
[Z1] ACCESSORIES: 2m cable with SCHUKO, CEE male blue 32A or red 32A plug
The laboratory power supply is supplied with a 2m connection cable with matching plug:
Output power ≤ 3300W - SCHUKO
Output power > 3300W - CEE plug blue 32A 230V
Output power ≥ 6000W - CEE plug red 32A 400V
[E] 19-inch rack-mount version
The laboratory power supply is supplied with rack-mount brackets (only models below 10kW).
[U] Ext. analogue control U
Input for external control of the output voltage via an analogue control signal.
[L] Ext. analogue control I
Input for external control of the output current via an analogue control signal.
[F] Ext. analogue feedback output U
Returns the actual value of the output voltage.
[G] Ext. analogue feedback output I
Returns the actual value of the output current.
[A] Interlock & External Output On/Off Control
Input for controlling the status of the laboratory power supply's output (On/Off), switchable either as "Interlock" or external control.
[R] Reverse current protection
Protection against reverse currents during operation with a large inductive or capacitive load.
[V] Polarity changer
To reverse the output polarity during operation.
[S] Remote measurement
Measuring the voltage at the consumer and compensating for line losses.
[Y] Programmable
The high-performance power supply unit is enhanced by a 4.3″ colour display and a more advanced digital control unit. In addition to the standard connectivity (RS232, RS485), a LAN port and USB (host) are installed. The upgraded control unit allows the power supply to be programmed autonomously with complex voltage/current characteristics over time.
Support for Existing Devices
If you have questions about existing DP-D devices, please provide us with the model and serial number, as well as the specific configuration. For new projects, we can advise you on selecting a current power supply with the appropriate voltage, current, and power ranges.
