Wiseman XRC Series 70 kV / 120 W X-ray Tube High-Voltage Power Supply

Overview

The Wiseman XRC Series is a digitally controlled, modular high-voltage power supply engineered specifically for driving grounded-cathode X-ray tubes in analytical, industrial, and research-grade instrumentation. Based on a high-efficiency zero-current resonant (ZCS) topology and DSP-based real-time regulation, the XRC delivers exceptional voltage stability (≤25 ppm/hr after thermal equilibrium), ultra-low ripple (0.1% RMS at ≤20 kHz), and precise filament current control — all within a compact, convection-cooled chassis. Its design adheres to fundamental requirements of X-ray source excitation: deterministic voltage/current setpoint tracking, sub-millisecond response to load transients, and intrinsic safety compliance for integration into CE- and FDA-regulated systems. As an OEM-optimized solution, the XRC eliminates the need for external HV conditioning or filament driver modules, reducing system footprint and interconnect complexity while maintaining full traceability of output parameters under GLP/GMP-aligned operating conditions.

Key Features

• Programmable output voltage range: 10–70 kV DC (positive polarity), with factory-set discrete taps (10, 15, 20, 30, 40, 50, 60, 70 kV)
• Constant-power operation up to 120 W; optional custom power ratings available upon request
• Universal AC input (85–265 VAC, 47–63 Hz) with active PFC and <1% THD
• Integrated, closed-loop filament supply (0–5 A / 0–10 V), automatically disabled when HV output falls below 30% of rated value — preventing cathode damage
• Dual-control architecture: local multi-turn potentiometers + remote analog (0–10 V) and digital (RS-232) interfaces compliant with Modbus RTU protocol
• Comprehensive protection suite: overvoltage lockout (OVP), arc detection with auto-recovery, output short-circuit shutdown, and hardware-enforced safety interlock circuitry
• High-precision monitoring: isolated 0–10 V analog outputs for real-time HV and tube current feedback (±1% accuracy at full scale)
• Thermally robust design: operating ambient range 0–50 °C; storage range −40–85 °C; conformal-coated PCBs for humidity resilience (20–85% RH, non-condensing)
• EMI-optimized layout meeting CISPR 11 Class B limits; no external filtering required for typical lab environments

Sample Compatibility & Compliance

The XRC Series is validated for use with grounded-cathode X-ray tubes from Kevex, Oxford Instruments, RTW, Superior, Varian, Trufocus, and major domestic manufacturers. It supports applications requiring stable Bremsstrahlung and characteristic line excitation across energy ranges from ~1 keV (for light-element fluorescence) to >60 keV (for high-Z transmission imaging). The unit complies with IEC 61010-1:2010 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and meets essential requirements of the EU Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU). Its analog and digital control interfaces support audit-trail-capable operation when integrated with software platforms compliant with FDA 21 CFR Part 11 and ISO/IEC 17025 data integrity provisions.

Software & Data Management

While the XRC operates autonomously via front-panel controls or analog signals, its RS-232 interface enables bidirectional communication with host systems using ASCII command sets. Standard firmware supports readback of actual HV, tube current, filament current, temperature, and fault status registers — all timestamped with millisecond resolution. Integration with LabVIEW™, Python (pySerial), or MATLAB® is facilitated by open documentation and example scripts. When deployed in regulated environments (e.g., ISO 17025-accredited labs or pharmaceutical QC), the XRC’s deterministic response and repeatable setpoint settling (<100 ms to ±0.01%) support documented calibration procedures per ASTM E1316 and ISO 11452-2. Optional firmware upgrades enable event logging to external SD cards or network-attached storage for long-term trend analysis and regulatory review.

Applications

• X-ray fluorescence (XRF) spectrometers for elemental composition analysis (RoHS, mining, metallurgy)
• In-line thickness gauging of paper, plastic films, aluminum foil, and coated substrates
• Real-time density and moisture measurement in continuous manufacturing processes
• Micro-focus X-ray imaging for PCB layer alignment, solder joint inspection, and wire bond verification
• Energy-dispersive X-ray spectroscopy (EDS) in SEM/TEM systems requiring stable tube bias
• Portable and benchtop XRD/XRF analyzers where size, weight, and thermal management are critical
• Research-grade X-ray sources for synchrotron pre-alignment, radiation hardness testing, and detector calibration

FAQ

Is the XRC compatible with floating-cathode X-ray tubes?
No — the XRC is designed exclusively for grounded-cathode configurations. Floating or anode-grounded tubes require alternative topologies not supported by this series.
Can output voltage be ramped programmatically?
Yes — via RS-232 or analog 0–10 V input, with slew rate configurable in firmware (default: 100 V/s; minimum step resolution: 1 V).
What is the mean time between failures (MTBF) under continuous operation?
Based on accelerated life testing per MIL-HDBK-217F, MTBF exceeds 50,000 hours at 25 °C ambient and 70% load.
Does the unit include a built-in high-voltage cable or connector?
No — HV output is provided via a standardized SHV female receptacle; users must specify cable length, shielding, and termination type during ordering.
Is calibration certification included with shipment?
Each unit ships with a NIST-traceable calibration report (per ISO/IEC 17025) covering HV output, current measurement, and filament regulation at three load points.
