Wisman DEA Series Portable Chassis High-Voltage Power Supply (10 kV, 20 W)

Overview

The Wisman DEA Series is a compact, portable-chassis high-voltage DC power supply engineered for precision instrumentation applications requiring stable, low-noise, and highly regulated output up to 10 kV at 20 W. Built upon Wisman’s proprietary linear power conversion architecture—distinct from switching topologies—the DEA series delivers exceptional voltage stability, sub-25 ppm/°C temperature coefficient (with optional TC10 variant), and ultra-low output ripple. Its design prioritizes electromagnetic compatibility (EMC) and noise immunity: differential analog voltage programming (±10 VDC reference) minimizes susceptibility to ground loops and ambient electrical interference, making it especially suitable for sensitive laboratory environments where signal integrity is critical. The unit complies with IEC 61010-1 for measurement, control, and laboratory equipment safety, and its robust thermal management enables continuous operation within 0–50 °C ambient conditions without derating.

Key Features

• Linear-regulated architecture ensuring high reproducibility and minimal transient response overshoot
• Output range: 1–10 kV DC (model-specific), 20 W maximum continuous power
• Stability of <0.01% per hour after 30-minute thermal stabilization; <0.02% over 8-hour period
• Differential analog interface (±10 VDC input) with ±2% full-scale output accuracy at nominal setpoint
• Load and line regulation ≤0.01%, supporting consistent performance across variable load and input conditions
• Integrated protection circuitry: real-time arc detection, programmable overcurrent limit, and fail-safe short-circuit handling with automatic recovery
• Flexible control architecture supporting local front-panel operation, analog remote control, and digital host communication via RS-232, RS-485, or Ethernet (optional)
• Compact chassis form factor optimized for integration into OEM analytical systems—including mass spectrometers, X-ray generators, and electrostatic process tools

Sample Compatibility & Compliance

The DEA series is specifically designed for integration into analytical and scientific instruments where high-voltage biasing, acceleration, or charging functions are required. It is widely deployed as the high-voltage source for mass spectrometer ion optics, electron multipliers, and detector biasing circuits. Its electrical isolation, creepage/clearance margins, and reinforced insulation meet IEC 61010-1 Edition 3 requirements for Pollution Degree 2 and Overvoltage Category II installations. While not certified to FDA 21 CFR Part 11 or ISO 13485 out-of-the-box, the unit supports audit-ready data logging and access control when integrated with compliant host software—enabling traceable operation in GLP/GMP-aligned laboratories. All units undergo 100% functional burn-in and high-potential (hi-pot) testing at 1.5× rated output voltage prior to shipment.

Software & Data Management

The DEA series supports bidirectional digital communication for configuration, monitoring, and closed-loop control. Standard firmware includes non-volatile parameter storage, real-time telemetry (output voltage/current, status flags, fault logs), and timestamped event history. When connected via RS-232 or Ethernet, users may integrate the supply into LabVIEW, Python (PySerial/PyVISA), or MATLAB environments using ASCII command sets. Optional Wisman-supplied PC software provides GUI-based calibration, ramp profiling, and automated test sequencing—compatible with Windows 10/11 and supporting CSV export for QA documentation. Audit trails—including user login, parameter changes, and fault events—are recordable when hosted on validated systems meeting ALCOA+ principles.

Applications

• Mass spectrometry: Ion source biasing, quadrupole rod drivers, and electron multiplier HV supply
• Electrostatic processing: Electrospinning, electrospray deposition, and charged particle beam focusing
• Industrial surface treatment: Electrostatic painting, flocking, and powder coating
• Scientific instrumentation: Particle accelerator pre-acceleration stages, ion implantation beamlines, and X-ray tube anode/cathode supplies
• Materials testing: Dielectric strength evaluation, insulation resistance validation, and corona discharge studies
• R&D infrastructure: High-voltage bias for photomultiplier tubes (PMTs), avalanche photodiodes (APDs), and gas detectors

FAQ

Is the DEA series compatible with mass spectrometers requiring ultra-stable HV bias?
Yes—its <0.01%/hr stability, differential analog interface, and <25 ppm/°C temperature coefficient make it suitable for MS ion optic biasing where drift-induced mass calibration errors must be minimized.
Can the output voltage be modulated dynamically during operation?
Yes—via analog input (0–10 V = 0–100% output) or digital commands (RS-232/Ethernet), with typical slew rate configurable up to 100 V/s depending on model and load capacitance.
Does the DEA support remote interlock and safety shutdown signals?
Yes—it features a hardware-enabled interlock input (dry contact or TTL-compatible) that immediately disables HV output upon assertion, satisfying Class 1 interlock requirements per IEC 61010-1.
What is the warranty and service support structure for international customers?
Wisman offers a standard 24-month limited warranty covering materials and workmanship. Technical documentation, firmware updates, and application engineering support are available in English through authorized regional distributors.
Can the DEA be customized for non-standard voltage ranges or mechanical interfaces?
Yes—Wisman maintains an OEM engineering team capable of modifying output range (e.g., 15 kV), adding custom connectors, integrating shielding, or adapting chassis dimensions per customer mechanical drawings and EMC specifications.
