Wiseman XN Series 50 kV / 50 W X-ray Tube High-Voltage Power Supply

Overview

The Wiseman XN Series is a compact, high-stability, high-voltage DC power supply engineered specifically for driving grounded-cathode X-ray tubes in analytical, industrial, and research-grade instrumentation. Operating on a resonant zero-current switching (ZCS) topology, the XN delivers regulated high voltage up to 50 kV with output power of 50 W—optimized for low-duty-cycle, precision X-ray generation where spatial resolution, spectral fidelity, and long-term repeatability are critical. Its design eliminates traditional transformer-based bulkiness without compromising electrical integrity: dielectric strength, creepage/clearance distances, and partial discharge suppression meet IEC 61010-1 requirements for measurement and control equipment. Unlike general-purpose HV supplies, the XN integrates a fully adjustable filament driver (0–3.5 A / 0–5.5 V), enabling precise thermionic emission control—essential for stable tube current regulation and minimizing anode thermal drift during extended operation.

Key Features

• Ultra-compact form factor: 75 mm × 75 mm × 205 mm (H×W×D), 45% smaller than the legacy XRN series; ideal for space-constrained OEM integration in portable or benchtop XRF, thickness gauges, and inline process analyzers.
• High regulation performance: output stability ≤0.05% over 8 hours after warm-up; load and line regulation both ≤0.01%; temperature coefficient ≤25 ppm/°C for both voltage and current outputs.
• Low-noise HV output: ripple ≤0.1% peak-to-peak at full load—critical for reducing spectral broadening in energy-dispersive X-ray fluorescence (EDXRF) and minimizing artifacts in digital radiography.
• Dual-control architecture: local multi-turn potentiometer adjustment + analog remote control (0–10 V input for HV and tube current); supports closed-loop feedback integration in automated systems.
• Integrated filament supply: independently adjustable 0–3.5 A current and 0–5.5 V voltage, with dedicated monitoring outputs—enables dynamic filament compensation for aging tubes or varying vacuum conditions.
• Comprehensive protection suite: overvoltage lockout (OVP), short-circuit foldback, interlock-enabled HV enable/disable, and thermal shutdown—designed for unattended operation in GLP-compliant environments.
• Digital interface options: factory-configurable USB 2.0, RS-232, RS-422, or Ethernet (TCP/IP stack) for remote parameter setting, real-time telemetry (HV, current, filament status), and firmware updates.

Sample Compatibility & Compliance

The XN Series is compatible with grounded-cathode X-ray tubes from Kevex, Oxford Instruments, RTW, Superior, Varian, TruFocus, and major domestic Chinese manufacturers. It supports common tube geometries used in microfocus and minifocus configurations—including those requiring integrated bias for focal spot stabilization. All units are CE-marked per IEC 61000-6-3 (emission) and IEC 61000-6-4 (immunity), and conform to IEC 61010-1 for safety in laboratory and industrial settings. While not FDA 510(k)-cleared, the XN meets essential electrical safety and EMC criteria required for Class I medical device subsystems (e.g., in non-diagnostic portable XRF analyzers). For ISO/IEC 17025-accredited labs, traceable calibration reports (NIST-traceable HV and current measurements) are available upon request.

Software & Data Management

Wiseman provides the XN Control Suite—a Windows-based configuration and monitoring application supporting all digital interface variants. The software enables full parameter logging (HV, tube current, filament voltage/current, temperature), alarm history export (CSV), and programmable ramp profiles for soft-start sequences. When deployed with Ethernet connectivity, the XN supports Modbus TCP register mapping for integration into SCADA or MES platforms (e.g., Siemens SIMATIC, Rockwell FactoryTalk). Audit trail functionality—including user login timestamps, parameter change logs, and firmware version tracking—meets basic ALCOA+ data integrity principles for QC/QA workflows. Remote firmware updates preserve backward compatibility and include cryptographic signature verification.

Applications

The XN Series serves as the high-voltage backbone in diverse X-ray-based instrumentation: handheld and benchtop XRF spectrometers for RoHS screening and alloy verification; online thickness gauges for aluminum foil, paper, and polymer film production; X-ray fluorescence liquid level sensors in chemical reactors; micro-CT preclinical imaging subsystems; PCB solder-joint inspection systems; and portable XRD/XRF hybrid analyzers for cultural heritage artifact authentication. Its low EMI profile and stable output make it suitable for applications demanding high signal-to-noise ratio—such as low-Z element detection in EDXRF or high-resolution backscatter imaging in security scanning. In R&D labs, the XN’s programmable filament control facilitates systematic studies of tube aging, electron optics optimization, and beam hardening correction modeling.

FAQ

What X-ray tube types are supported?
The XN is designed for grounded-cathode tubes only. It is not compatible with floating-cathode or bipolar configurations.
Is the filament supply galvanically isolated from the high-voltage output?
Yes—the filament circuit features reinforced isolation rated to 5 kV DC, ensuring safe operation with cathodes referenced to ground potential.
Can the XN be operated in constant-power mode?
No—it operates in constant-voltage/constant-current mode only. Power is determined by the product of set HV and tube current; users must manage loading within the 50 W limit.
Does the unit support analog monitoring outputs for HV and current?
Yes—0–10 V DC scaling outputs are provided for both HV and tube current, calibrated to ±1% accuracy.
What is the recommended minimum warm-up time before achieving specified stability?
30 minutes is required to reach thermal equilibrium; stability specifications apply only after this period under constant ambient conditions (23 ±2 °C).
