Microcomputer relay protection calibrator

JB-2000 Relay Protection Calibration Instrument is an ideal testing instrument for verifying relay protection devices. It adopts single-chip microcomputer technology and consists of an automatic synchronous digital millisecond meter, logic control unit, multifunctional digital display unit, high-precision data acquisition and processing unit, current and voltage output unit. It is a fully automatic and intelligent relay protection calibration tester developed in the early stage of power based on the testing requirements of on-site relay protection and the support of GB7261-2008, DL/T995-2006 standards.

JB-2000Microcomputer relay protection calibratorProduct advantages:

1. The display screen has a functional display unit, which can clearly reflect the working status of the machine from the display screen.

2. High degree of intelligence, with just one button, all parameters of the universal relay can be measured and all data can be automatically printed, freeing you from the tedious testing operations.

3. All printed data uses Chinese characters, such as' suction voltage ',' disconnection voltage ',' normally open suction time ', etc.

4. Equipped with comprehensive self checking and self-protection functions, the JB-2000 fully automatic single-phase relay protection tester immediately engages in self checking upon startup. In the event of overload or overtravel, the protection circuit will quickly cut off the output and emit sound and light reminders, greatly reducing unnecessary losses caused by misoperation.

JB-2000Microcomputer relay protection calibratorTechnical parameters:

1. AC voltage output

Continuously adjustable from 0 to 250V, with a maximum output capacity of 600VA, over range protection of 260V, and an error of ± 1%.

2. AC current output

0~50A, 0~100A continuously adjustable, with an error of ± 1%.

When the voltage is between 0 and 50A, the open circuit voltage is 10V.

When 0~100A, the open circuit voltage is 5V. The overload protection action current is 120A.

3. DC voltage output

Continuously adjustable from 0 to 250V, maximum current 2A, over range protection 260V, overload protection action current 2.1A ± 5%. Ripple coefficient S ≤ 0.1%

4. DC current output

0~200mA 0~5A continuously adjustable, with an error of ± 1%.

When 0-5A, the open circuit voltage is 24V, and the overload protection action current is 5.2A.

5. Fixed DC voltage output

When outputting 110V or 220V separately, the current can reach 2.5A, but when outputting both AC voltage and DC voltage simultaneously.
