High-Voltage Power Supply 0 … 130 kV 0 … 0.0092 A 1.2 kW – DP130K-0-0092HV

The DP-HV series combines constant-voltage and constant-current control with intuitive local or external operation. LED indicators and precision rotary controls facilitate setup and monitoring directly on the unit. Standard models and custom designs up to 300 kV are available for electrostatic applications, material testing, and industrial test setups.

Analog 0 … 10V control and measurement interfaces are included as standard equipment. When ordered with RS485, Modbus RTU handles digital communication instead of analog I/O. The standard interlock loop is retained in this version as well.

The DP-HV series combines high output voltages with compact enclosures. A temperature-dependent fan control system adjusts cooling to match operating conditions. Depending on the model, the units can be used as freestanding units or mounted in a rack. The required rack mounts are included with the unit.

The dimensions of the selected model are critical for installation planning. Custom versions may vary. The maximum values for the series include customer-specific units and cannot be achieved simultaneously with every standard model.

Controlling High Voltage from a PC

A simple Windows control software program is included with the DP-HV series and supports operation via the optional RS485 interface. Using Modbus RTU, you can set setpoints and read actual values. The documented protocol also makes it easier to integrate the system into your own test programs.

Tailor Protection to the Load
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, a suitable additional protective circuit must be provided. The power supply is not an energy sink with unlimited capacity. In particular, when switching off inductive loads and when discharging capacitors, current, voltage, and load energy must remain within the agreed limits.

Analog Integration or Modbus Connection

Analog I/O (Standard)
Using 0 … 10 V signals, you can set the output voltage and output current and read their actual values. Four active-low open-collector outputs indicate voltage mode, current mode, error status, and the HV output status. A +15 V auxiliary reference with a maximum load capacity of 50 mA completes the interface.

Interlock Loop (Standard)
The loop on pins 9 and 10 is also present in models equipped with RS485. In local operation, a closed loop enables the output, while an open loop disables it. In remote operation, the loop controls the output externally. The operating and connection requirements for the ordered model are described in the manual.

RS485 with Modbus RTU (optional)
The digital version replaces the analog I/O. Analog setpoint input, measured value feedback, status outputs, and auxiliary reference are then not available in parallel. The interlock loop remains intact. This allows the external output enable to be used even in a digitally controlled test stand.
