Structure:
This instrument adopts a metal profile frame, which is high in strength and light in weight. Themicrocomputer relay protection testerhas an aluminum alloy case, which is portable, sturdy and durable. It is not easy to be 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 deviceThe 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 the power supplies and combining them with the AC/DC digital voltmeter, ammeter, and digital millisecond meter, a measurement assembly is formed. It can flexibly and conveniently detect the working parameters of various relay protection relays currently in use, and can independently complete the detection work without the need for any other instruments.
