Sequential Phase Relay Protection Tester Price

I. Performance Features:

1. Featuring microcomputer control and at least 16 touch switches on the panel, it allows for convenient completion of various testing functions. It is equipped with self-check and error reporting capabilities for easy inspection and maintenance.

2. Comprehensive self-inspection and self-protection features ensure that the circuit can quickly cut off the output and emit both audio and visual alerts during overload or excessive range, reducing unnecessary losses caused by improper operation.

3. With intelligence, simply press one button to measure all parameters of a general relay and automatically print all data.

4. The display features functional display units, allowing the working status to be clearly reflected on the screen.

5. All printed data is in Chinese characters, such as "Closing Voltage," "Opening Voltage," and "Normal Open Closing Time," etc. (Note: The display uses a digital tube and does not have printing capabilities.)

Technical Specifications:

1. Output Voltage Range: Continuously adjustable from 0 to 500V, with a high output capacity of 6000VA, overvoltage protection at 500V, and an accuracy of ±0.25%.

AC Current Output

At 0-50A, the open-circuit voltage is 5V.

At 0-100A, the open-circuit voltage is 10V. Overload protection trips at 300A.

At 0-200A and 0-600A, the open circuit voltage is 10V.

2. Direct Current Voltage Output:

0-320V continuous adjustable, high current of 2A, over-range protection at 320V.

Overload protection action current: 2.1A ±5%.

3. Direct Current Output:

0-200mA, 0-5A, 0-20A continuously adjustable, with an accuracy of ±0.25%.

At 0-200mA, the open-circuit voltage is 48V, and the overload protection trips at 230mA.

At 0-5A, the open circuit voltage is 24V, and the overload protection trips at 5.2A.

At 0-20A, the open-circuit voltage is 36V.

4. Fixed Direct Current Voltage Output

Outputting 110V or 220V individually, the current can reach up to 2.5A, but with alternating voltage and current,

When outputting DC voltage simultaneously, the total capacity cannot exceed 600VA.
