Overview
The Wiseman XFN Series is a compact, high-stability, negative-polarity high-voltage power supply engineered specifically for driving grounded-anode X-ray tubes in laboratory and industrial analytical instrumentation. Based on zero-current resonant (ZCS) topology and advanced high-voltage insulation design, the XFN delivers precisely regulated negative DC output from –10 kV to –70 kV with power ratings spanning 10 W to 100 W. Its integrated floating filament supply (0.3–5 A, adjustable with programmable preheat) enables stable thermionic emission control across diverse tube geometries and operating conditions. The module operates from a single 24 V DC input, minimizing system-level power conversion complexity and thermal load—making it especially suitable for space-constrained OEM platforms such as benchtop XRF analyzers, portable XRD systems, and inline thickness gauges. With long-term output stability better than 0.05% over 8 hours and ripple <0.1% peak-to-peak under full load, the XFN meets the stringent voltage regulation requirements of quantitative X-ray applications where spectral resolution and count-rate consistency depend directly on HV source fidelity.
Key Features
- Compact modular architecture: Standard footprint (205 × 75 × 185 mm for 10–50 kV models; 228.5 × 75 × 185 mm for 60–70 kV), optimized for rack-mount or embedded integration.
- Negative high-voltage output: Selectable fixed-output variants (–10, –20, –30, –40, –50, –65, –70 kV) with factory-calibrated accuracy traceable to NIST-certified standards.
- Integrated filament supply: Fully isolated, current-regulated filament driver with soft-start and preheat sequencing to extend X-ray tube lifetime and reduce thermal shock.
- Multi-mode control interface: Local adjustment via precision multi-turn potentiometer; remote analog control (0–10 V); digital communication via USB 2.0, RS-232, RS-485, or optional Ethernet (TCP/IP).
- Comprehensive protection suite: Hardware-based overvoltage lockout (OVP), overcurrent limit (OCP), arc detection with automatic recovery, and safety interlock circuitry compliant with IEC 61010-1 Class I requirements.
- Low EMI design: Optimized shielding and ZCS switching minimize conducted and radiated emissions—critical for co-location with sensitive detectors and low-noise amplifiers.
Sample Compatibility & Compliance
The XFN series is validated for use with globally sourced grounded-anode X-ray tubes requiring negative high voltage and floating filament bias—including common models from Oxford Instruments, Spellman, Comet, and Thermo Fisher Scientific. It supports operation within ambient temperatures from 0 °C to +50 °C and relative humidity up to 85% non-condensing, conforming to IP20 environmental classification. While not a standalone medical device, the XFN complies with key electromagnetic compatibility (EMC) directives (IEC 61326-1 for laboratory equipment) and safety standards applicable to Class I, SELV-limited power supplies (IEC 61010-1). For GLP/GMP-regulated environments, its analog and digital control interfaces support audit-trail-capable software integration when paired with validated host applications.
Software & Data Management
Wiseman provides Windows-compatible configuration and monitoring software supporting real-time readback of HV output, filament current, status flags, and fault logs. All digital interfaces (USB, RS-232/485, Ethernet) implement ASCII command protocols with CRC error checking and response acknowledgments. The software enables programmable ramp profiles, interlock state monitoring, and user-defined alarm thresholds. For automated test systems, DLL libraries and Python API wrappers are available for seamless integration into LabVIEW, MATLAB, or custom C++/C# applications. Remote voltage and current monitoring signals (0–10 V analog outputs) allow connection to external PLCs or DAQ systems without additional signal conditioning.
Applications
The XFN serves as the core HV excitation source in numerous X-ray-based analytical and metrology platforms, including but not limited to: energy-dispersive X-ray fluorescence (EDXRF) spectrometers; handheld and benchtop X-ray diffraction (XRD) instruments; real-time thickness measurement systems for metal plating and polymer films; density gauges in mining and recycling; cable eccentricity analyzers; diamond and gemstone authenticity verification tools; mineralogical phase identification units; PCB layer alignment systems; and multi-layer substrate inspection stations. Its combination of stability, compactness, and flexible control makes it particularly valuable in portable, battery-operated, or field-deployable instruments where size, weight, and power efficiency are primary constraints.
FAQ
Is the XFN compatible with all grounded-anode X-ray tubes?
Yes—provided the tube’s rated negative HV and filament current fall within the selected XFN model’s specifications. Tube datasheets must be cross-referenced for maximum cathode-anode voltage differential and filament power requirements.
Can multiple XFN units be synchronized for dual-tube or multi-beam configurations?
Not natively—but external master-slave triggering is possible using TTL-compatible interlock lines and shared analog setpoint references, enabling coordinated start-up and shutdown sequences.
Does the XFN support FDA 21 CFR Part 11 compliance?
The hardware itself does not enforce electronic signature or audit trail functions; however, when integrated with validated third-party software that implements Part 11 controls, full regulatory compliance can be achieved at the system level.
What is the recommended maintenance interval?
No scheduled maintenance is required. The solid-state design eliminates consumables; periodic visual inspection of connectors and cooling vents is advised every 12 months in continuous-use environments.
Is calibration traceable to national standards?
Yes—each unit undergoes final calibration using metrology-grade HV dividers and current shunts calibrated per ISO/IEC 17025-accredited procedures, with certificate of conformance supplied.
