Introduction

This document presents technical details for Wisman's XRD series X-ray generators, designed for applications such as plastics sorting, crystal inspection, plating measurement, diamond inspection, mineral analysis, X-ray fluorescence (XRF), X-ray diffraction (XRD), and wavelength dispersive spectroscopy (WDS).

Typical Applications

• Research and Development (R&D)
• Industrial and scientific X-ray analysis systems

Product Overview

The Wisman XRD series offers X-ray generators with output voltage ranges from 20kV to 160kV and output power options of 300W, 600W, and 1200W. These generators support various X-ray tubes from multiple manufacturers, making them suitable for OEM integration. Key features include a compact design, wide input voltage range, and standard analog interfaces for easy system integration.

The series supports both floating filament (negative high voltage polarity) and ground-referenced filament (positive high voltage polarity) configurations. Digital Signal Processor (DSP)-based control circuitry ensures excellent emission current regulation and stability. Communication interfaces include RS-232, RS-485, and Ethernet options.

Key Specifications

Interfaces and Controls

The XRD series provides multiple control and monitoring interfaces:

• Analog Interface: Includes inputs for current and voltage programming (0-10 Vdc), filament limit and preheat controls, and outputs for voltage/current monitoring.
• Digital Interface: RS-232 and RS-485 serial communication options for remote control and monitoring.
• Ethernet Interface: Optional ET interface for network connectivity.

Additional features include safety interlocks, over-voltage, over-temperature, short circuit, and arc protection, as well as floating or grounded filament configurations.

Physical Characteristics

The generator weighs approximately 21 kg. Detailed mechanical dimensions are provided for various polarity and filament configurations to assist with system integration.

Safety and Customization

• Safety interlock mechanisms are included to ensure safe operation.
• OEM customization options are available to tailor the generator to specific application requirements.

Summary of Critical Parameters and Best Practices

• Ensure input voltage compatibility: 90-264Vac for 300W units, 180-264Vac for higher power units.
• Maintain operating temperature within 0°C to +50°C for optimal performance.
• Use provided analog and digital interfaces for precise control and monitoring.
• Leverage safety features such as interlocks and protection circuits to prevent damage.
• Consider filament configuration (floating vs grounded) based on application needs.
• Allow a 2-hour warm-up period to achieve stability specifications.
