Wiseman XRN Series 70 kV / 100 W X-ray Tube High-Voltage Power Supply

Overview

The Wiseman XRN Series is a precision-engineered, compact high-voltage DC power supply specifically designed for driving X-ray tubes in analytical, industrial, and laboratory instrumentation. Based on zero-current resonant (ZCS) topology and advanced high-voltage insulation architecture, the XRN delivers stable, low-noise, and highly regulated output across a wide range of operating conditions. It supports both cathode-grounded and anode-grounded X-ray tube configurations—making it compatible with major OEM tubes including Kevex, Oxford Instruments, RTW, Superior, Varian, Trufocus, and domestic Chinese manufacturers. Its core function is to provide precisely controlled accelerating voltage (6–70 kV) and filament heating power (0–3.5 A, 0–5.5 V) to enable consistent X-ray photon generation for applications requiring high spectral fidelity and long-term measurement repeatability.

Key Features

• Wide programmable output range: 9 discrete maximum voltage settings (6, 10, 20, 30, 40, 50, 60, 65, and 70 kV) paired with 6 selectable power ratings (10, 30, 50, 65, 75, and 100 W) to match diverse tube load requirements.
• High regulation performance: Voltage and current regulation better than ±0.001% over full load and input line variation (±10%), ensuring minimal drift during extended acquisition cycles.
• Ultra-low output ripple: ≤0.01% peak-to-peak of rated voltage—critical for minimizing spectral broadening in XRF and XRD systems where energy resolution depends directly on HV stability.
• Dual control modes: Local multi-turn potentiometer adjustment and analog 0–10 V remote interface for both high voltage and beam current, enabling seamless integration into automated test benches and process control systems.
• Integrated filament supply: Independently adjustable 0–3.5 A / 0–5.5 V filament output with closed-loop thermal compensation, supporting precise thermionic emission control without external bias circuitry.
• Robust thermal and temporal stability: ≤25 ppm/°C temperature coefficient; ≤0.01%/hour short-term stability post warm-up; ≤0.02%/8-hour long-term drift—meeting GLP-compliant instrument qualification requirements.
• Compact chassis-mount form factor (65 × 115 × 150 mm) optimized for OEM integration into space-constrained analytical platforms such as handheld XRF analyzers, inline thickness gauges, and benchtop X-ray fluorescence spectrometers.

Sample Compatibility & Compliance

The XRN series is validated for use with commercially available sealed and open-type X-ray tubes used in materials analysis, non-destructive testing (NDT), and process monitoring. It meets electromagnetic compatibility (EMC) requirements per IEC 61326-1 for laboratory equipment and conforms to safety standards aligned with IEC 61010-1 (Measurement, Control, and Laboratory Use). Wiseman’s internal quality system is certified to ISO 9001:2008, and all units undergo 100% burn-in and functional verification at rated load before shipment. While not FDA-cleared or CE-marked as a medical device, the XRN complies with general-purpose industrial safety directives applicable to Class I, double-insulated HV supplies. For GMP/GLP environments, optional RS232-enabled variants (e.g., XRN65P100-RS232) support audit-trail-capable parameter logging and firmware-upgradable control protocols.

Software & Data Management

Standard XRN models feature analog 0–10 V interfaces for real-time voltage and beam current modulation, fully compatible with PLC-based automation and LabVIEW™ DAQ systems via NI USB-6009 or similar analog I/O modules. Optional RS232-equipped variants provide ASCII command-set control (e.g., “HVSET 65000”, “FILSET 2.8”) with status feedback (e.g., “HVREAD?”, “CURR?”, “TEMP?”), enabling traceable parameter setting, runtime diagnostics, and integration into LIMS or MES workflows. All digital variants include configurable watchdog timers and hardware interlock inputs (TTL-compatible) to meet functional safety requirements in industrial deployment scenarios. Firmware updates are performed via serial bootloader—no proprietary software required.

Applications

• X-ray fluorescence (XRF) spectrometry for elemental composition analysis in mining, metallurgy, and RoHS/WEEE compliance testing.
• Online thickness measurement of aluminum foil, paper, plastic films, and PCB substrates using transmission X-ray attenuation principles.
• Real-time density and basis weight monitoring in continuous web processes (e.g., paper mills, steel coating lines).
• Microfocus X-ray imaging and computed tomography (CT) subsystems for electronics inspection, weld integrity assessment, and additive manufacturing QA.
• Energy-dispersive X-ray spectroscopy (EDS) integration with SEM and EPMA platforms requiring stable, low-noise tube bias.
• Portable and benchtop X-ray diffraction (XRD) systems where size, efficiency, and thermal management are critical constraints.

FAQ

Is the XRN compatible with both grounded-anode and grounded-cathode X-ray tubes?
Yes—the XRN series supports bipolar grounding configurations and includes isolated filament drive circuitry to accommodate either topology without external modification.
What is the typical warm-up time to achieve specified stability?
Full thermal stabilization occurs within 30 minutes; voltage and current outputs meet ±0.01%/hr stability specifications after this period.
Can multiple XRN units be synchronized for dual-tube or multi-beam systems?
While not inherently synchronized, external trigger and analog reference sharing (e.g., common 10 V reference rail) enables phase-aligned ramping and coordinated operation in multi-source setups.
Does Wiseman offer custom calibration certificates traceable to NIST or national metrology institutes?
Yes—upon request, factory calibration reports with uncertainty budgets and traceability statements can be provided for ISO/IEC 17025-aligned QA programs.
Are there thermal derating curves available for continuous operation at 40°C ambient?
Derating data is included in the technical manual; at 40°C ambient, full-rated output is maintained up to 70% of maximum power, with linear reduction to 50% at 50°C.
