Wiseman XDF60kV/4kW High-Voltage Power Supply for X-ray Tubes

Overview

The Wiseman XDF60kV/4kW is a precision-engineered, 19-inch rack-mountable high-voltage power supply specifically designed to drive laboratory and industrial X-ray tubes in demanding analytical applications. Operating on the fundamental principle of regulated DC high-voltage generation with integrated filament excitation, the XDF series delivers stable, low-ripple output essential for consistent X-ray photon flux and spectral fidelity. Its architecture employs zero-current resonant switching and advanced high-voltage insulation design—enabling high efficiency, minimal electromagnetic interference (EMI), and long-term operational reliability under continuous duty cycles. The unit is engineered for seamless integration into X-ray diffraction (XRD), X-ray fluorescence (XRF), and microfocus imaging systems where voltage stability (<100 ppm/h), current reproducibility, and real-time remote controllability are critical to measurement integrity.

Key Features

• Wide-output range: Continuously adjustable high-voltage output from 0 V up to 60 kV, with selectable maximum ratings (10–70 kV variants available)
• High-power capability: Rated for up to 4 kW continuous output; dual-configurable variants support either positive HV (4 kW) or negative HV (3 kW) with floating AC/DC filament supplies
• Integrated filament regulation: Fully adjustable filament voltage (0–12 V_AC/DC) and current (0–5 A standard, up to 12 A on request), independently controlled and thermally decoupled from HV stage
• Comprehensive protection suite: Hardware-enforced overvoltage, overcurrent, short-circuit, arc detection, overtemperature, and safety interlock monitoring—each with latching fault indication and automatic shutdown
• Dual-control architecture: Local operation via front-panel multi-turn potentiometers and 4-digit LED meters (±1% full-scale accuracy); remote analog control via 0–10 V signals for both HV and filament parameters
• Digital connectivity: Standard Ethernet and RS-232 interfaces enable SCPI-compliant command sets; optional RS-485 supports multi-drop configurations in distributed lab networks
• Rack-optimized mechanical design: 3U (132 mm) height, 19″ EIA-compliant chassis with forced-air cooling, rated for ambient operation from 0 °C to +50 °C
• Low-noise performance: Output ripple specified at ≤0.1% peak-to-peak plus 1 V_rms; voltage coefficient ≤25 ppm/°C (custom coefficients available)

Sample Compatibility & Compliance

The XDF60kV/4kW is compatible with grounded-cathode and grounded-anode X-ray tube configurations—including OEM tubes from Kevex, Oxford Instruments, RTW, Superior, Varian, Trufocus, and major domestic manufacturers. Its electrical interface (DB50 I/O connector) provides dedicated pins for HV enable/disable, interlock loop closure, analog monitor outputs (0–10 V proportional to actual kV/mA), and filament status signaling. While the unit itself carries no regulatory certification (e.g., UL/IEC 61010-1) as a component-level power supply, it is routinely deployed in final equipment certified to IEC 62494-1 (X-ray equipment safety), ISO 17025 (testing laboratories), and FDA 21 CFR Part 11 when paired with validated host software that implements electronic signatures and audit trails. Its design adheres to electromagnetic compatibility (EMC) best practices for Class A industrial environments per CISPR 11.

Software & Data Management

Remote operation is supported through ASCII-based SCPI commands over RS-232 or TCP/IP. Standard firmware enables readback of real-time kV, mA, filament current, internal temperature, and fault status registers. When integrated into automated platforms—such as those used in synchrotron beamlines or QA/QC XRF workflows—the XDF can be synchronized with data acquisition engines via TTL triggers or time-stamped analog monitors. Optional LabVIEW™ drivers and Python API wrappers are available upon request. All digital control actions (setpoint changes, enable toggles, reset commands) generate timestamped log entries accessible via serial query, supporting traceability requirements under GLP and GMP frameworks. No embedded storage is included; persistent logging must be implemented externally by the host system.

Applications

• X-ray diffraction (XRD) systems requiring stable kV/mA for phase identification and crystallite size analysis
• Energy-dispersive and wavelength-dispersive XRF spectrometers demanding precise excitation control for quantitative elemental mapping
• Micro-CT and industrial computed tomography stations where dose consistency directly impacts reconstruction fidelity
• Academic and national lab research setups involving custom-built X-ray sources, plasma diagnostics, or electron beam pre-acceleration stages
• OEM integration into portable or benchtop X-ray analyzers where compact 3U form factor and low EMI are mandatory

FAQ

What X-ray tube configurations does the XDF60kV/4kW support?
It supports both grounded-anode and grounded-cathode tube topologies, with configurable polarity (positive or negative HV output) and isolated filament supplies optimized for thermal stability.
Is the unit compliant with FDA 21 CFR Part 11 for regulated laboratories?
The hardware provides the necessary digital I/O and logging-capable communication protocols; full Part 11 compliance depends on the host software architecture and validation protocol implemented by the end-user system integrator.
Can output voltage and current be monitored remotely in real time?
Yes—via analog monitor outputs (0–10 V = 0–100% of setpoint) or digital queries returning ASCII-formatted values with millisecond response latency.
What cooling method is used, and what are the acoustic emissions?
Forced-air convection using low-noise centrifugal fans; typical sound pressure level is ≤52 dBA at 1 m distance under full load.
Are custom voltage/current ranges or mechanical interfaces available?
Yes—Wiseman offers engineering collaboration for modified output specs, alternate connectors (e.g., SHV, MHV), front-panel layout adjustments, and extended environmental hardening (e.g., conformal coating, enhanced ingress protection).
