Three Phase Secondary Current Injection Testing Equipment for Relay Testing
Secondary Current Injection Testing Equipment
Introduction:
The Secondary injection testing equipment is a new type of miniaturized microcomputer relay protection tester. This device has super little cubage and high precision. It has the advanced functions of big machine and also has the dependability and facilitation of small machine.
Features:
1. High performance Industrial control computer is adopted as the controlling computer.
2. True color LCD display, tracking ball and optimized keyboard can be used without an external mouse and keyboard.
3. You can access data, communicate data and upgrade software conveniently.
4. The operation is simple and convenient, and is easy to be mastered.
5. High-speed digital controlling processor is adopted as the output core of the tester.
6. High precision D/A converter is employed for ensuring the precision and linearity of current and voltage in the whole range.
7. Voltage and current amplifier
8. Digital input and output
9. Auxiliary DC power supply output for special use
