Wisman DA60P2 100kV/2kW Rack-Mount High-Voltage DC Power Supply

Overview

The Wisman DA60P2 is a precision-engineered, 19-inch rack-mountable high-voltage DC power supply designed for demanding laboratory and industrial applications requiring stable, controllable output up to 100 kV at 2 kW. Based on solid-state switching topology with multi-stage regulation and active feedback control, the DA60P2 delivers ultra-low ripple (<0.1% P-P + 1 Vrms), exceptional long-term stability (<100 ppm/h after thermal equilibrium), and precise line/load regulation (voltage adjustment rate: 0.005% + 5 V; current adjustment rate: 0.01% ± 100 µA). Its architecture integrates galvanically isolated sensing, redundant protection circuitry, and fail-safe interlock logic—ensuring operational integrity in safety-critical environments such as electron beam generation, X-ray tube biasing, and electrostatic process systems.

Key Features

• Wide output range: Continuously adjustable from 0.5 kV to 100 kV DC, with maximum power delivery of 2 kW across the full voltage span
• High-fidelity regulation: Temperature coefficient of 100 ppm/°C (customizable to lower values); stability maintained below 100 ppm/h post-warm-up
• Dual-mode control: Local adjustment via front-panel multi-turn potentiometers or remote analog control (0–10 V input for both voltage and current setpoints)
• Comprehensive digital interface: Standard RS-232 port supports SCPI-compatible command sets; optional RS-422 available for noise-immune industrial networks
• Integrated safety system: Real-time monitoring and automatic shutdown for overvoltage, overcurrent, short-circuit, arc detection, overtemperature, and interlock breach
• Modular expandability: Optional function modules—including Constant Power Control (CPC), Low-Ripple (LR), Floating Ground (FGLL), Arc-Trip (AT), and Custom Soft-Start (SS(X))—enable application-specific configuration
• Robust mechanical design: 3U (132 mm) height, 19″ EIA-compliant chassis; forced-air cooling with thermally monitored fans; operating ambient: 0–50 °C

Sample Compatibility & Compliance

The DA60P2 is compatible with a broad class of high-impedance, low-current loads typical in physics research and industrial electrostatic systems—including electron/ion beam columns, electrospinning nozzles, corona discharge electrodes, electrophoretic separation cells, and dielectric withstand test fixtures. Its output isolation, grounding flexibility (including optional floating ground), and low leakage characteristics meet requirements for sensitive instrumentation interfacing. The unit is CE-marked per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and its design adheres to IEC 61010-1:2010 for safety in laboratory electrical equipment. While not inherently FDA 21 CFR Part 11 compliant, audit-ready logging and alarm event capture—when used with Wisman’s proprietary remote monitoring software—support GLP/GMP-aligned validation protocols where traceable parameter history is required.

Software & Data Management

Wisman provides a Windows-based remote control and monitoring application supporting real-time telemetry of output voltage, current, internal temperature, and status flags. The software enables programmable limit setting (upper/lower bounds for voltage/current), configurable alarm triggers with on-screen and audible notifications, and timestamped event logging exportable to CSV. All control commands are logged with user ID and execution time—facilitating basic audit trail functionality. For integration into automated test systems, the RS-232 interface supports standard SCPI syntax (e.g., VOLT? , CURR? , VOLT 50000 , OUTP ON ) and allows synchronization with LabVIEW, Python (PySerial), or MATLAB via ASCII command scripting. Remote voltage/current metering outputs (0–10 V signals via JP1 header) support connection to third-party DAQ systems or analog chart recorders.

Applications

• Electrostatic processes: Electrospinning, electrospraying, electrostatic coating, flocking, and precipitator systems
• Scientific instrumentation: Biasing of X-ray tubes, electron multipliers, mass spectrometer ion sources, and particle accelerator components
• Materials testing: Dielectric strength evaluation, insulation resistance verification, and corona aging studies
• Industrial R&D: Capacitor charging for pulsed power, high-energy capacitor banks, and laser excitation circuits
• Life sciences: High-voltage electrophoresis (e.g., pulsed-field gel electrophoresis power stages), plasma sterilization modules
• Environmental engineering: Electrostatic smoke/ash removal, VOC abatement reactors, and ionized air purification systems

FAQ

Is the DA60P2 suitable for continuous-duty operation at full rated power?
Yes—the unit is thermally rated for uninterrupted 2 kW output under specified ambient conditions (≤50 °C) with proper airflow. Derating is recommended above 40 °C ambient or in confined enclosures.

Can the output polarity be reversed?
The DA60P2 is configured as a positive-output, negative-return (ground-referenced) supply by default. Bipolar or negative-output variants are available as custom configurations upon request.

What safety certifications does the DA60P2 hold?
It carries CE marking for EMC and Low Voltage Directive compliance. UL/CSA certification is not included but can be pursued via third-party testing for specific regional deployments.

Does the unit support analog voltage/current monitoring outputs?
Yes—JP1 header provides isolated 0–10 V signals proportional to actual output voltage and current, calibrated to full-scale reading, enabling external analog recording or PLC interfacing.

Is firmware update capability available?
Firmware updates are performed via RS-232 using Wisman’s dedicated utility; version history and update logs are retained internally for traceability during maintenance audits.
