High-Voltage Power Supply 0 ... 5kV 0 ... 1A 5kW - DP50H-1PH

In the development of High-Voltage Power Supplies of the DP-PH Series, special emphasis was placed on versatility, high performance, precision and stability. In addition to the usual basic functions of such units, such as precisely adjustable voltage and current values, overvoltage and overcurrent protection, and automatic switching between CC (constant current/current source) and CV (constant voltage/voltage source) modes, the DP-PH Series can be controlled via modern digital interfaces RS232, RS485, RS422 to set and record output values. The ARM architecture-based digital control loop provides fast response times and constant monitoring of output values, resulting in high stability and accuracy. Supporting the Modbus RTU protocol, the High-Voltage Power Supply can be easily integrated into a new or existing infrastructure and interact with Labview, while it can also be operated completely independently via front panel controls.

High-Voltage Power Supplies of the DP-PH Series in various versions

High-quality components and extensive experience in the development of laboratory and industrial power supplies enable compact dimensions despite high power and voltage. Intelligent cooling regulates the speed depending on the set output parameters and temperature, so that the high-voltage power supply only responds with an increase in speed when it is really needed. DP-PH series high-voltage laboratory power supplies deliver up to 1.2 kW of power from a 19" 2U 1/2-width cabinet, which allows two devices to be mounted side by side in a 3U slot (with adapter). In addition, DP-PH series laboratory power supplies can be mounted in racks cabinet sizes used freestanding in all cabinet sizes – the appropriate mounting accessories for rack installation are included free of charge with all devices in 2U and 3U designs. Suitable mounting accessories for two 19″ 2U 1/2 devices in one slot can be ordered separately.

Attention: Enclosure size may vary for certain models, please refer to the data sheet.

DP-PH Series High-Voltage Laboratory Power Supplies Software Suite

Because the development of the DP-PH series high-voltage power supplies focused on laboratory applications with high demands on precision and automation, laboratory power supplies in this series come with a comprehensive software suite for Windows 10 & 11 that leaves almost nothing to be desired. Whether it's simple adjustment and monitoring of output values or programming of repetitive complex voltage/current curves – everything can be done quickly and easily. The power supply can be connected via RS485, RS232, or RS422, and communication via Modbus RTU guarantees low latency and reliable data transmission.

Expand your DP-PH series high-voltage power supply with additional functions—even after purchase.

High-Voltage Power Supplies of the DP-PH Series are compatible with many optional expansion modules of the AP Series, so you are no longer bound to the configuration you selected when ordering, but can also expand certain functions at a later date via external modules. In addition, the AP Series is continuously being expanded and maintained with new modules, so that you can also expand existing units in the future with new functions that we will introduce.

Currently, the following AP Series expansion modules are compatible with DP-PH Series laboratory power supplies:

Model AP9: Combined reverse current protection (inductive and capacitive loads)

Depending on the maximum voltage and current, the module is manufactured in a 19″ 1U 1/2, 2U, or 3U design and protects your power supply from reverse currents that can occur when operating with large capacitive or inductive loads. This means you do not need any additional protective circuitry between the power supply and your load, which greatly reduces the effort involved.

Model AP8: Additional EMC filter with capacitance on the output side

Some loads require a cleaner voltage than the power supply unit can provide in its basic configuration, or, conversely, generate very strong interference (e.g., due to high-frequency current consumption with very steep edges—square wave), which can affect the control of the power supply unit at high currents. For these cases, we have developed the AP8 module, which combines a three-stage EMC filter with a large fast capacitance to further stabilize the output voltage of the power supply unit in critical applications and to protect the power supply unit from influences caused by loads. This combination guarantees a stable output voltage even under maximum load from complex high-frequency loads.

Equipped with RS232, RS422, and RS485 as standard with full Modbus RTU support, DP-PH series high-voltage power supplies can be quickly and effectively integrated into your existing infrastructure. An analog status output (fault/normal) and interlock loop are also available as standard.

Digital interfaces RS232, RS422 & RS485 (standard)

Equipped with RS232, RS422 and RS485 connections as standard, with full support for the Modbus RTU protocol, laboratory power supplies of the DP-PH Series allows both integration into existing infrastructures and the development of new infrastructure. The open Modbus RTU protocol allows customised control solutions to be implemented quickly and effectively, so that nothing stands in the way of automation.
