Wiseman XRL Series 130 kV / 200 W X-ray Tube High-Voltage Power Supply Module

Overview

The Wiseman XRL Series is a compact, high-stability DC-DC high-voltage power supply module engineered specifically for driving cold-cathode and thermionic X-ray tubes in analytical, industrial, and portable X-ray instrumentation. Operating on resonant zero-current switching topology and advanced high-voltage insulation design, the XRL delivers precisely regulated output voltages up to 130 kV with continuous power up to 200 W. Its architecture supports both positive- and negative-polarity high-voltage outputs—enabling compatibility with either grounded-cathode (e.g., Kevex, Oxford, Varian) or floating-cathode (e.g., Trufocus, RTW, domestic OEM) X-ray tube configurations. The module integrates a fully adjustable, low-noise filament supply (0–10 V / 0–5 A) with programmable preheat sequencing, ensuring optimal electron emission stability and tube longevity. With long-term output stability better than 100 ppm/h after thermal equilibrium and ripple maintained below 0.1% peak-to-peak of full-scale voltage, the XRL meets stringent requirements for quantitative XRF, XRD, thickness gauging, and real-time elemental analysis where signal-to-noise ratio and measurement reproducibility are critical.

Key Features

• High-voltage DC-DC conversion with configurable output range: 20–130 kV (standard models include 20, 30, 40, 50, 60, 70, 80, 100, and 130 kV variants)
• Output power options: 75 W, 90 W, 120 W, 140 W, and 200 W — selected per application duty cycle and thermal envelope
• Dual-mode filament supply: digitally adjustable 0–10 V / 0–5 A output with dedicated preheat enable/disable logic and load regulation <0.01%
• Triple-control architecture: local multi-turn potentiometers, analog 0–10 V remote setpoint interface, and bidirectional digital communication via RS-232, RS-422, RS-485, or USB
• Comprehensive protection suite: hardware-latched overvoltage cutoff, current-limit foldback, arc-sensing circuitry with sub-microsecond response, and configurable safety interlock inputs compliant with IEC 61508 SIL-2 functional safety principles
• Ultra-low electromagnetic emissions: optimized layout and shielding minimize conducted and radiated EMI, facilitating integration into sensitive detector-based systems without additional filtering
• Convection-cooled mechanical design: 260 × 100 × 170 mm footprint enables direct mounting inside compact X-ray housings or OEM instrument chassis

Sample Compatibility & Compliance

The XRL series is validated for use with commercially available sealed and open-type X-ray tubes requiring stable, low-ripple excitation—including models from Kevex, Oxford Instruments, RTW, Superior, Varian, Trufocus, and leading Chinese manufacturers. It supports both grounded-anode (positive HV) and grounded-cathode (negative HV) tube topologies. All units are designed and tested in accordance with IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use), including dielectric withstand (≥2× rated output + 1 kV AC), creepage/clearance distances, and enclosure ingress protection (IP20 baseline). While not certified as standalone medical devices, XRL modules are routinely integrated into Class IIa/IIb IVD instruments meeting ISO 13485 quality system requirements and FDA 21 CFR Part 820. Firmware-level audit trails, secure parameter locking, and deterministic command-response timing support compliance with GLP and GMP environments when deployed in regulated QA/QC labs.

Software & Data Management

Digital control is implemented via ASCII-command protocol over serial interfaces (RS-232/RS-422/RS-485) or vendor-provided USB-to-serial drivers. Commands support real-time readback of actual HV voltage (±1% accuracy), beam current (±1%), filament voltage/current (±2%), and internal temperature. Optional firmware extensions provide time-stamped logging of operational events (e.g., arc count, interlock triggers, overtemp warnings) compatible with CSV export for traceability. SDKs for Windows/Linux/macOS include C/C++, Python, and LabVIEW APIs. All configuration parameters—including voltage ramp rates, interlock thresholds, and filament preheat duration—are non-volatile and retain settings across power cycles. Remote firmware updates are supported via signed binary upload with CRC32 validation, satisfying change control requirements under ISO/IEC 17025 Clause 7.7.

• Portable and benchtop XRD analyzers for crystalline phase identification in pharmaceuticals and catalysts
• In-line elemental composition monitoring in recycling streams, cement production, and mining beneficiation
• Microfocus X-ray imaging for PCB solder-joint inspection, multilayer alignment, and wire-bond defect detection
• Density and porosity measurement in composite materials, ceramics, and additive-manufactured parts
• Capacitor charging stages in pulsed X-ray generators and neutron generator driver circuits

FAQ

What X-ray tube types are compatible with the XRL series?
The XRL supports both grounded-cathode (negative HV output) and grounded-anode (positive HV output) tubes. Verified compatibility includes Kevex, Oxford, Varian, Trufocus, RTW, and major domestic OEMs.
Does the XRL meet electromagnetic compatibility (EMC) requirements for lab instrumentation?
Yes — its resonant topology and internal shielding limit radiated emissions to Class B limits per CISPR 11. Conducted emissions comply with EN 55011 when installed with recommended input filtering.
Can the filament supply be operated independently of the high-voltage output?
Yes — filament voltage and current can be enabled/disabled separately via digital command or interlock logic, enabling safe tube conditioning sequences.
Is remote calibration or field adjustment of output accuracy supported?
No — factory-calibrated transfer functions are stored in tamper-resistant memory; end users may only adjust operating setpoints, not calibration coefficients.
What is the expected service life under continuous operation at 80% rated load?
Based on accelerated life testing and MTBF modeling, mean time between failures exceeds 25,000 hours at ≤45 °C ambient with derated output power.
