Wiseman MEA Series 30 kV / 15 W AC-Input Precision High-Voltage Power Supply Module

Overview

The Wiseman MEA Series is a high-stability, air-insulated, AC-input high-voltage power supply module engineered for precision applications in analytical instrumentation, scientific research, and industrial systems requiring tightly regulated DC high voltage. Based on zero-current resonant switching topology and proprietary high-voltage insulation design, the MEA delivers exceptional long-term stability, ultra-low ripple, and robust arc immunity—critical for sensitive downstream devices such as mass spectrometer ion sources, electron multipliers, and electrostatic field generators. Unlike general-purpose HV supplies, the MEA is specifically optimized for instrument-grade integration: its low stored energy (<200 mJ), fast-acting arc recovery, and dual analog control interface enable seamless synchronization with feedback loops in closed-loop vacuum or plasma systems. The module operates without forced cooling, supports both positive and negative polarity outputs, and is designed for continuous-duty operation within laboratory and controlled industrial environments (0–50 °C ambient).

Key Features

• AC-input architecture with dual-range compatibility: 105–125 VAC or 210–250 VAC, 48–63 Hz (400 Hz input supported for aerospace and specialized OEM use)
• Precision output range: selectable fixed-output models from 1 kV to 30 kV; all rated at 15 W continuous power
• Ultra-low output ripple: ≤0.05% peak-to-peak of full-scale voltage under rated load, verified per IEEE Std 510-1983 test methodology
• Thermal and temporal stability: ≤0.01% drift per hour after 30-minute thermal stabilization; ≤0.05% over 8-hour period; temperature coefficient ≤25 ppm/°C
• Comprehensive protection suite: programmable overvoltage lockout (OVP), overcurrent limit (OCP), real-time arc detection with sub-millisecond response, and hardware-enforced safety interlock circuitry compliant with IEC 61010-1 Category II
• Dual control modes: local adjustment via front-panel multi-turn potentiometer + remote analog interface (0–10 V for voltage and current setpoints, isolated and buffered)
• Air-insulated construction with recessed HV output port; standard 1 m shielded HV cable terminated in metal-threaded connector for EMI suppression
• OEM-optimized mechanical design: compact chassis (292 × 133 × 83 mm for ≤15 kV; 349 × 133 × 83 mm for 20–30 kV), DB15 I/O connector housing analog monitoring (0–10 V output monitor signals), status flags, and interlock inputs

Sample Compatibility & Compliance

The MEA series is validated for integration into analytical platforms where high-voltage integrity directly impacts measurement fidelity—including quadrupole and time-of-flight mass spectrometers, electrostatic precipitators, corona discharge ionizers, and dielectric withstand testers. Its low electromagnetic emissions meet Class B limits per EN 55011 and are compatible with adjacent low-noise detectors (e.g., PMTs, Faraday cups). All units are manufactured under ISO 9001-certified processes and undergo 100% burn-in and hipot testing at 120% rated voltage. For regulated environments, the analog control and monitoring architecture supports audit-trail-capable data logging when paired with compliant SCADA or LIMS systems—enabling alignment with GLP, GMP, and 21 CFR Part 11 requirements for instrument qualification (IQ/OQ/PQ).

Software & Data Management

While the MEA operates as a standalone analog-controlled module, its 0–10 V monitor outputs (voltage and current) are fully compatible with third-party DAQ systems (e.g., National Instruments PXI, Keysight U2300A) and LabVIEW-based control frameworks. Wiseman provides detailed pinout documentation, timing diagrams, and isolation specifications for safe integration into validated software environments. Optional firmware-enabled digital interfaces (RS-485 Modbus RTU or CANopen) are available under OEM agreement—supporting remote configuration, fault logging, and synchronized ramp profiling. All analog signals maintain ±1% accuracy across temperature and lifetime, traceable to NIST-calibrated references.

Applications

• Mass spectrometry: Ion source biasing, detector dynode chain supply, and collision cell voltage control
• Materials science: Dielectric strength testing of polymers, ceramics, and thin-film insulators per ASTM D149 and IEC 60243
• Plasma & beam physics: Electrostatic lens arrays, ion accelerator pre-acceleration stages, and electron beam focusing
• Industrial electrostatics: Spray charging in precision coating systems, particulate separation in air filtration, and static neutralization in cleanroom handling
• Biomedical research: Nanosecond-pulsed electric field (nsPEF) generation for electroporation studies, seed irradiation in mutagenesis protocols
• OEM instrumentation: Embedded HV subsystem in portable X-ray fluorescence analyzers, handheld corona testers, and automated HV continuity checkers

FAQ

Is the MEA series suitable for use in UL/CE-certified instruments?
Yes—the MEA complies with IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and meets EMC immunity/performance criteria per EN 61326-1. Final system-level certification remains the responsibility of the integrating OEM.
Can output polarity be reversed in-field?
Polarity is fixed per unit order (positive or negative output); reversal requires hardware modification and is not user-serviceable. Dual-polarity variants are available upon OEM request.
What is the maximum allowable load capacitance?
For stable operation and arc recovery performance, total connected capacitance must remain below 1 nF. External snubbers or dV/dt limiting networks may be required for capacitive loads exceeding this threshold.
Does Wiseman provide calibration certificates?
Standard units ship with factory test reports. NIST-traceable calibration certificates (ISO/IEC 17025 accredited) are available as an option under extended warranty or OEM service agreements.
Is convection cooling sufficient for continuous 15 W operation at 30 kV?
Yes—thermal modeling and accelerated life testing confirm full-rated output at 50 °C ambient with no derating, provided minimum 5 mm clearance around all sides for unrestricted airflow.
