Structure:
This instrument adopts a metal profile frame, with high strength and light weight. Themicrocomputer relay protection tester has an aluminum alloy case, which is portable, sturdy and durable. It is not easily affected by moisture and dust pollution during storage, ensuring proper protection of the instrument and guaranteeing its service quality.
Working Principle:
This instrument consists of the following circuit units:
110V/220V fixed output DC voltage unit
0~250V variable output DC voltage unit
0~250V variable output AC voltage unit
0~100A/10A variable output AC current unit
0~5A variable output DC current unit
AC/DC dual-use digital voltmeter, AC/DC dual-use digital ammeter, and digital millisecond meter.Relay protection device The above five AC/DC power supply units can be selected through the control mechanisms on the panel according to different test objects. By choosing one (or three) of these power supplies and combining them with the AC/DC digital voltmeter, ammeter, and digital millisecond meter, a measurement combination is formed. This allows flexible and convenient detection of the working parameters of various relay protection relays currently in use, and the detection can be completed independently without the need for any other instruments.
