Wiseman DR Series Rack-Mount High-Voltage DC Power Supply

Overview

The Wiseman DR Series is a precision-engineered, 19-inch rack-mountable high-voltage DC power supply designed for demanding scientific, industrial, and research applications requiring stable, reversible polarity, and ultra-low-noise output up to 300 kV and 6 kW. Based on solid-state modular architecture with active regulation and multi-stage filtering, the DR platform employs closed-loop feedback control to maintain exceptional voltage stability and low ripple under dynamic load conditions. Its core measurement principle relies on high-frequency switching topologies coupled with precision analog feedback networks—ensuring sub-100 ppm/h long-term drift performance after thermal stabilization. Unlike conventional transformer-rectifier systems, the DR series delivers true bipolar operation without external polarity-switching hardware, enabling seamless transition between positive and negative high-voltage output states. This capability is critical in applications such as electrostatic beam steering, ion acceleration, and pulsed electron gun biasing where rapid polarity reversal directly impacts experimental repeatability and system synchronization.

Key Features

• Reversible polarity output from ±1 kV to ±300 kV, fully programmable via front-panel or remote interface
• Rated continuous output power up to 6 kW with forced-air or optional liquid cooling configurations
• Ultra-low output ripple: ≤0.1% peak-to-peak plus 1 Vrms, verified per IEC 61000-4-30 Class A compliance methodology
• Thermal stability of 25 ppm/°C; optional low-drift variants available for metrology-grade environments
• Comprehensive protection suite: overvoltage lockout (OVP), overcurrent limit (OCL), short-circuit foldback, arc detection with <10 µs response, overtemperature shutdown, and hardware-enforced safety interlock circuitry meeting IEC 61010-1 Category III requirements
• Dual-mode analog control: internal multi-turn potentiometers and external 0–10 V reference inputs for independent voltage and current setpoints
• Standard communication interfaces include IEEE 802.3 Ethernet (TCP/IP, Modbus TCP) and RS-232; RS-485 available as factory option for industrial fieldbus integration
• Front-panel 4-digit LED display with ±1% full-scale accuracy; remote monitoring via JP1 analog outputs (0–10 V proportional to actual V/I)
• Constant Power Control (CPC) mode optionally enabled for capacitor charging, pulsed load emulation, and energy-storage system testing
• CE-marked and compliant with EN 61326-1 (EMC) and EN 61010-1 (safety) for laboratory and industrial deployment

Sample Compatibility & Compliance

The DR Series supports direct integration with a broad range of high-voltage instrumentation including electron guns, X-ray tubes, electrostatic precipitators, ion implantation chambers, and pulsed laser diode drivers. Its output connector design—featuring recessed insulated bushings and standardized HV cable termination—meets IEC 61076-2-101 mechanical interface specifications for safe, repeatable mating cycles. All units undergo full burn-in and 72-hour thermal stress testing prior to shipment. The power supply architecture conforms to GLP and GMP-aligned documentation practices: full traceability of calibration certificates (NIST-traceable standards), firmware version logging, and configurable audit trail generation for regulatory submissions. While not FDA 21 CFR Part 11 certified out-of-the-box, the DR’s Ethernet interface supports third-party validation packages for electronic record integrity in pharmaceutical and medical device R&D labs.

Software & Data Management

Wiseman provides the DR-Link Control Suite—a cross-platform application (Windows/macOS/Linux) supporting real-time parameter monitoring, waveform capture (up to 10 kS/s sampling), and script-based sequencing. Configuration files are stored in human-readable JSON format with SHA-256 checksums for version control. Remote access is secured via TLS 1.2 encryption and configurable user roles (Operator, Technician, Administrator). Logged data exports comply with ASTM E2500-13 Annex A3 for raw instrument data archiving, including timestamps synchronized to UTC via NTP. For integration into SCADA or LIMS environments, the DR supports Modbus TCP register mapping and OPC UA companion specification v1.04. Firmware updates are delivered as signed binary packages with dual-bank memory architecture to ensure fail-safe rollback capability.

FAQ

What is the minimum voltage resolution achievable with the DR series?
The analog control input accepts 0–10 V signals with 16-bit DAC resolution, yielding approximately 153 mV step size for a 300 kV range. Internal digital setpoint resolution is 20 bits, supporting sub-0.1 V adjustment at lower output ranges.
Can the DR be operated in constant power mode without custom firmware?
Yes—CPC functionality is implemented in hardware and activated via dedicated command register (Modbus address 40052); no firmware modification required.
Is the high-voltage output referenced to earth ground?
All DR models feature floating output architecture; grounding configuration (positive/negative/center-tap) is user-selectable via rear-panel jumpers per IEC 61000-4-5 surge immunity guidelines.
How does the arc detection system differentiate between transient noise and actual arcing?
Arc detection combines dV/dt monitoring, current slew-rate analysis, and spectral signature recognition in FPGA logic—rejecting EMI events above 100 MHz while triggering within 5 µs for true dielectric breakdown events.
Does Wiseman provide calibration services traceable to national standards?
Yes—factory calibration uses Fluke 8508A multimeters and Keysight B2912B SMUs, all maintained under ISO/IEC 17025-accredited procedures; on-site recalibration kits and accredited third-party service partnerships are available globally.
