HTJB-V Protection Relay Test Set

Description

 Products features

1. As the instrument is controlled by microcomputer, the only *6 touching switches on the front panel may conveniently operate various test functions. Which improve the disadvantages of old relay protection Calibrator**-if you want to switch different power sources, you must turn off power supply and change-over multiple switches. This tester has the function of self-inspection and error reporting, which providing great convenience for inspection and maintenance.

2. The tester is equipped with complete self-inspection and self-protection function. After starting-up, the tester begins self-inspection immediately. In case of over load and over range, protection circuit may cut off output and warn you by sound and light, that reduces unnecessary loss resulting from wrong operation. 

3. The tester is in high intelligent. Only touching one key, it can test the whole parameters for universal relay and print all data automatically, which free you from troublesome operation.

4. The display screen has function display unit, you can see operation state of the tester from display screen.

5. The printed data by the tester is all in Chinese such as “ Operating Voltage”,“Opening Voltage”,“NORM OPN Operating Time” and so on.

1. AC voltage output

0~**0V continuous modulation with max output capacity **0VA, over-range protection **0V and error is±1%.

2. AC current output

0~*0A,0~**0A continuous modulation and error is±1%.

At 0~*0A,open-circuit voltage is *0V.

At 0~**0A,open-circuit voltage is 5V.Over-load protection action current is **0A.

3. AC voltage output

0~**0V continuous modulation with max current 2A, over-range protection **0V, over-load protection action current is 2.1A±5% and error is±1%.

4.DC current output

0~**0mA, 0~5 A continuous modulation with error ±1%.

At 0~**0mA,open-circuit voltage *8V, over-load protection action current is **0mA.

At 0~5A, open-circuit voltage*4V, over-load protection action current is 5.2 A.
