High-Voltage Power Supply 0 ... 6kV 0 ... 0.2A 1.2kW - DP60H-02PH

For controlled high-voltage testing, the DP-PH series combines digital CC/CV control with convenient front-panel operation and serial remote control. RS-232 and RS-485 with Modbus RTU allow you to set output values and integrate measured values into your test sequence.

A LAN interface with server/client operation is available as an option, as is—independently of this—an analog I/O package that replaces RS232 and enables the control of voltage and current, as well as the feedback of both actual values via 0 … 5V, 0 … 10V, or 4 … 20mA. An interlock loop and status output are included as standard features.

Suitable for laboratory workstations and racks

From compact half-width units to high-performance full-width models, the DP-PH series offers a variety of chassis sizes to suit your setup. The temperature-dependent fan control adjusts cooling based on the load. Full-width units can be mounted using the included rack brackets or used as freestanding units. A shared rack insert for two half-width units is available separately.

Semi-wide units can be identified by the suffix -S. For special versions and specific model dimensions, the confirmed technical specifications apply.

Select the appropriate output range
For high-voltage models, the lower limit of the voltage adjustment range may be greater than 0 V. The model list shows the actual adjustable range. Models up to and including 1500 V are potential-free by default. Higher-voltage versions have a grounded output with the specified polarity. Remote measurement is not supported by the DP-PH series.

Software Suite for DP-P and DP-PH

Recurring voltage and current waveforms can be programmed, executed, and recorded using the software suite. Use the digital interfaces or the optional LAN connection to integrate the device into your test process. The documented Modbus RTU protocol for the serial interfaces also simplifies the development of custom control systems and integration into LabVIEW applications. Direct operation via the front panel remains possible regardless.

Expand your high-voltage power supply with features tailored to your load and test procedure. The AP9, AP7, and AP5 modules, which are custom-built, are available for the DP-PH series. The AP6 and AP8 are not compatible.

Integrated reverse-current protection and additional protection modules
The output rectifier stage already provides basic protection against same-polarity reverse currents within the device’s permissible limits. For high-energy loads or reverse voltage transients, the protection can be specifically supplemented. The power supply is not an energy sink with unlimited capacity. The required design depends on the reverse current, reverse voltage, and stored load energy.

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.

Model AP7: Additional Input-Side EMC Filter
When there are increased requirements on the mains side, the AP7 supplements the existing filtering with a three-stage EMC filter. This helps reduce conducted interference in demanding test and production environments. The single- or three-phase configuration and current-carrying capacity are selected to match the power supply unit.

Model AP5: Mechanical Isolation of the Load
Supplement the electronic output control with a physical isolation point between the power supply and the load or test bench. The AP5 is manufactured to match the voltage, current, and application, and is integrated into your system’s safety concept.

All AP modules are custom-built to order, with their enclosures and electrical configurations tailored to your application.

Flexibly Integrate Your High-Voltage Power Supply

Digital interfaces (standard)
, RS232, and RS485 with Modbus RTU enable the configuration and monitoring of output values. If analog I/O is selected, RS232 is not available.

LAN (optional)
Integrate the power supply into your network infrastructure. The LAN interface can be configured for server or client operation, depending on your application.

Analog I/O (optional)
The analog package connects external voltage and current setpoints to the feedback of both actual values. Select a common signal standard for all four functions: 0 … 5V, 0 … 10V, or 4 … 20mA. The package replaces RS232 and can be ordered independently of the optional LAN interface.

Interlock Loop (Standard)
The 5V loop blocks the output when the loop is open and enables it when the loop is closed. Upon request, it can be configured at the factory as an external output ON/OFF trigger. The user cannot switch between these two functions after installation.

Status Output (Standard)
The separate status output indicates the device status using 0 V for errors and 5 V for normal operation. It supplements the monitoring of your application independently of any optional analog actual value outputs.

Single-Unit Operation The DP-PH series is designed for single-unit operation and does not support master/slave operation or the parallel or serial connection of multiple power supplies.
