Wiseman MT30kV/60W High-Voltage DC Power Supply Module

Overview

The Wiseman MT30kV/60W is a high-precision, ultra-low-noise DC high-voltage power supply module engineered for demanding analytical and scientific instrumentation. Based on zero-current resonant switching topology and proprietary high-voltage insulation design, the MT series delivers stable, ripple-free output essential for sensitive detection systems where signal integrity and long-term drift are critical parameters. Its core architecture integrates galvanic isolation, six-sided electromagnetic shielding, and thermally optimized PCB layout to minimize conducted and radiated emissions—making it suitable for integration into mass spectrometers, electron optical columns, and radiation detection platforms operating under strict electromagnetic compatibility (EMC) requirements per EN 61326-1 and IEC 61000-4 standards.

Key Features

• Fixed-output or programmable high-voltage generation up to 30 kV DC with 60 W continuous power capability
• Ultra-low output ripple and noise: <0.001% peak-to-peak, measured across full load and temperature range
• High short-term stability: ±0.01% over 8-hour operation without recalibration
• Low thermal drift: 25 ppm/°C voltage coefficient ensures consistent performance in variable lab environments
• Comprehensive protection suite including arc detection, current-limiting short-circuit response, and automatic recovery
• Dual control modes: analog 0–5 V input or external 100 kΩ potentiometer for precise remote voltage adjustment
• Configurable polarity: factory-set positive or negative output; optional dual-polarity variants available upon request
• Compact convection-cooled form factor with EMI-suppressed metal enclosure—designed for OEM integration into space-constrained instrument chassis
• OEM customization support for voltage/current combinations, mechanical interfaces, safety interlocks, and regulatory labeling

Sample Compatibility & Compliance

The MT30kV/60W module is specifically qualified for use in vacuum-compatible, low-outgassing analytical systems including quadrupole and time-of-flight mass spectrometers, scanning electron microscopes (SEM), and electrostatic lens assemblies. It meets CE marking requirements under the Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU). While not inherently compliant with FDA 21 CFR Part 11, its analog control interface and stable output behavior support integration into GLP/GMP-compliant workflows when paired with validated system-level software and audit-trail-enabled controllers. The module conforms to IEC 61010-1 safety standards for measurement, control, and laboratory equipment, including reinforced insulation and creepage/clearance distances appropriate for 30 kV operation.

Software & Data Management

As a hardware-level DC power module, the MT30kV/60W does not include embedded firmware or digital communication protocols (e.g., RS-232, USB, or Ethernet). Its analog control interface enables seamless integration with third-party data acquisition systems, PLCs, or custom LabVIEW/Python-based instrument control suites. Users may implement closed-loop voltage regulation by feeding back monitored output via high-voltage dividers and precision ADCs. For traceable calibration, Wiseman provides NIST-traceable test reports and supports ISO/IEC 17025-accredited calibration services through authorized partners. All modules ship with comprehensive technical documentation—including schematics, thermal derating curves, and mounting torque specifications—for reproducible system integration.

Applications

The MT30kV/60W serves as a primary HV bias source in multiple high-sensitivity domains: ion source acceleration and focusing in mass spectrometry; detector biasing for photomultiplier tubes (PMTs), proportional counters, Geiger-Müller tubes, and scintillation detectors; electrostatic chuck (ESC) control in semiconductor metrology tools; electrophoretic separation systems requiring stable field gradients; and ESD immunity testing fixtures per IEC 61000-4-2. Additional use cases include DNA sequencing platforms utilizing nanopore sensing, protein extraction via electroporation, nuclear medicine imaging subsystems, and industrial X-ray tube excitation where compact size, low EMI, and thermal resilience are mandatory.

FAQ

Is the MT30kV/60W compatible with vacuum environments?
Yes—when installed with vacuum-rated feedthroughs and non-outgassing mounting hardware, the module operates reliably at pressures down to 10⁻⁵ mbar. Refer to Wiseman’s Vacuum Integration Guide for material compatibility and bakeout recommendations.
Can output polarity be reversed in-field?
No—polarity is fixed at manufacture. Dual-polarity versions require factory configuration and are subject to extended lead times.
What is the recommended method for monitoring actual output voltage?
Use a calibrated high-voltage divider (e.g., 1000:1 ratio) with ≤0.1% accuracy, connected to a 6½-digit DMM. Avoid direct probing due to loading effects and potential arcing.
Does Wiseman provide application-specific validation reports?
Yes—OEM customers may request system-level validation packages aligned with ISO 13485 (medical devices) or ISO 9001 (industrial instruments), including functional testing, thermal stress profiling, and EMC pre-scan reports.
Are replacement units calibrated to original specifications?
All replacement modules undergo full electrical verification against datasheet limits prior to shipment. Calibration certificates with measurement uncertainty budgets are available upon request.
