High-Voltage Power Supply 0 … 150 kV 0 … 0.01 A 1.5 kW – DP150K-001HV

9.305,80 € incl. VAT
The DP150K-001HV delivers 0–150 kV, 0–10 mA, and 1.5 kW of rated power. CC/CV control, analog I/O, and interlock are standard features. The grounded output has the polarity selected at the time of order.
Comes standard with analog 0 … 10V I/O and interlock. Optionally, RS485 with Modbus RTU can replace the analog I/O; the interlock loop remains intact. The grounded output is configured with positive or negative polarity as specified at the time of order. Simple Windows control software is included with the unit.
The DP150K-001HV combines 0–150 kV with 0–10 mA and 1.5 kW. It thus offers significantly more current reserve than lower-current models designed solely for field and insulation testing. Applications of interest include larger DC test benches, testing of high-voltage components, and electrostatic process development. Material and electrode setups with higher power requirements are also suitable.
The DP-HV series combines constant-voltage and constant-current control with intuitive local or external operation. LED indicators and precision rotary controls facilitate on-unit adjustment and monitoring. 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.
| Connectivity | Analog 0 … 10V control and measured value feedback are standard. Optional RS485 with Modbus RTU instead of analog I/O. The interlock loop remains intact. |
| Functionality | Constant-voltage and constant-current (CV/CC) operation with automatic switching. Local operation or external control. |
| Output configuration | Grounded output with positive or negative high voltage, depending on the version ordered. No remote measurement. |
| Safety | Protection against overvoltage, overcurrent, and overtemperature, as well as current limiting in the event of a short circuit. Standard interlock loop. |
| Accuracy | Voltage and current settings and display: ±0.5% FS, ±2 digits resolution; other specifications are listed by model. |
High Voltage in the Right Format
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.
| Housing W × H × D, depending on the model | 323 × 110 × 367 mm 440 × 110 × 360 mm 443 × 136 × 500 mm 460 × 136 × 580 mm |
| Installation and Setup | The dimensions of the selected model listed in the technical specifications are authoritative. |
Special versions may vary. The maximum values for the series include customer-specific units and are not achievable simultaneously with every standard model.
Full control over your testing process
Controlling High Voltage from a PC
Representative image of the software for the DP-HV series.
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.
Connection options
Analog Integration or Modbus Connection
Illustration of the back panel. The pin assignment depends on the configuration ordered.
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, thereby enabling external output enable even in a digitally controlled test bench.
