Wiseman DH Series 19″ Rack-Mountable High-Voltage DC Power Supply (150 kV / 2 kW)

Overview

The Wiseman DH Series is a precision-engineered 19-inch rack-mountable high-voltage DC power supply designed for demanding scientific, industrial, and R&D applications requiring stable, controllable, and highly protected kilovolt-level excitation. Based on solid-state switching topology with multi-stage regulation and active feedback control, the DH platform delivers regulated DC output from 0 to 150 kV (with 200 kV as a standard alternative and 300 kV available via custom engineering), at a continuous output power of 2 kW. Its architecture emphasizes metrological-grade stability—achieving <100 ppm/h drift after thermal stabilization—and ultra-low ripple (0.1% peak-to-peak plus 1 Vrms), enabling reliable operation in sensitive electrostatic processes, particle acceleration stages, and high-fidelity insulation testing protocols. The system is engineered for integration into automated test benches and compliance-driven environments, supporting both local front-panel operation and full remote supervision via industry-standard digital and analog interfaces.

Key Features

• True 19″ EIA-compliant rack-mount chassis (4U for 150 kV; 6U for 200/300 kV variants), optimized for laboratory and cleanroom deployment.
• Dual-mode voltage and current control: internal multi-turn potentiometers for manual setpoint adjustment; external 0–10 V analog inputs for programmable, closed-loop integration with PLCs, DAQ systems, or custom controllers.
• Comprehensive protection suite including fast-response overvoltage cutoff, current-limiting circuitry, arc-sensing logic, thermal shutdown, and hardware-enforced safety interlock loop compliant with IEC 61010-1 requirements.
• High-precision 4-digit LED display with ±1% accuracy across full output range; real-time readout of actual voltage and current values under load.
• Standard communication stack: isolated RS-232 and Ethernet (TCP/IP) for SCPI-compatible command execution, status polling, and firmware updates; optional RS-485 for multi-drop distributed control networks.
• Low-drift performance: temperature coefficient of 100 ppm/°C; line regulation < ±0.01% over ±10% input variation; load regulation < 0.01% from no-load to full-rated current.
• Robust mechanical design with recessed HV output port using insulated feedthrough and standardized metal HV connector; includes 1 m shielded HV cable with strain relief.

Sample Compatibility & Compliance

The DH Series is purpose-built for use with electrophoresis instrumentation, X-ray generators, electron/ion beam columns, electrostatic coating systems, and dielectric withstand testers. Its output characteristics meet the electrical interface requirements of ISO 13485-aligned medical device test setups and support GLP/GMP validation workflows when integrated with audit-trail-capable control software. The CE marking confirms conformity with the EU Electromagnetic Compatibility (2014/30/EU) and Low Voltage (2014/35/EU) Directives. While not intrinsically rated for hazardous locations, its enclosure meets IP20 environmental protection standards and supports installation in Class 1, Division 2 areas when housed within appropriate secondary enclosures. All units undergo factory calibration traceable to NIM (National Institute of Metrology, China) standards.

Software & Data Management

Remote operation is supported via ASCII-based SCPI commands over RS-232 or TCP/IP. A vendor-provided Windows application enables basic parameter configuration, real-time waveform logging, and alarm history export (CSV). For integration into LIMS or MES platforms, the Ethernet interface supports Modbus TCP mapping of key registers—including output voltage, current, status flags, and fault codes—enabling seamless data ingestion without proprietary middleware. Audit trail functionality (e.g., user login timestamps, parameter change logs) can be implemented externally via syslog forwarding or database logging through the host controller. The analog monitoring outputs (JP1 header) provide galvanically isolated 0–10 V signals proportional to measured voltage and current, compatible with third-party chart recorders or analog input modules meeting IEC 61000-4-5 surge immunity.

Applications

• Electrophoresis systems requiring precise, low-noise HV bias for DNA/protein separation.
• Capacitor charging circuits in pulsed-power research and laser pumping stages.
• Electrostatic processes: spray coating, flocking,纺丝 (electrospinning), air filtration, and particulate precipitation.
• High-energy physics instrumentation: electron gun biasing, ion source extraction, and beamline focusing elements.
• Destructive and non-destructive dielectric testing per ASTM D149, IEC 60270, and GB/T 16927.1.
• Accelerator subsystems, including RF cavity biasing and detector bias networks.
• Component burn-in and accelerated life testing of HV capacitors, diodes, and insulators.

FAQ

Is the DH series suitable for continuous-duty operation?
Yes—the DH platform is rated for 100% duty cycle at full output under forced-air cooling conditions within the specified ambient temperature range (0–50 °C).
Can output polarity be reversed?
Standard units are negative-polarity output; positive polarity or bipolar configurations are available as custom-engineered variants upon request.
Does the unit support analog voltage/current monitoring with external meters?
Yes—JP1 provides isolated 0–10 V signals proportional to actual output voltage and current, calibrated for direct connection to standard digital multimeters or analog chart recorders.
What safety certifications does the DH series hold?
All units carry CE marking per applicable EU directives; additional certifications (e.g., UL 61010-1, UKCA) may be pursued for specific export markets subject to regional testing and documentation requirements.
Is firmware update capability built-in?
Yes—Ethernet and RS-232 interfaces support secure firmware upgrades using signed binary packages; version history and checksum verification are implemented in bootloader firmware.
