The SCR Elektroniks 3 station RCCB/RCBO 28 Days and Temperature Rise Test Bench is economically designed to verify the 28 Days Test (21 hr ON, 3 hr OFF Test) and Temperature Rise of the parts of a Circuit Breaker.
Stand alone unit after initial configuration of test parameters: The panel is capable to generate accurate test results for a continuous period of 28 days as required in the 28 days test.
The test system is not suspeptible to test data loss due to utility power cut - the test begins from the point it got interrupted due to utility power cut.
Power Loss Measurement available as an extra feature.
Single / Three Phase operation possible.
Servo controlled mechanism to control current (+/- 1%) against incoming fluctuations.
Microcontroller based timer unit for quick and easy user interface and automated operation.
Inductors with tapping for each range will be provided for maintaining the open circuit voltage to 30V. This eliminates energy wastage during test.
User may opt for test bench with heating chamber for testing at 60.
Adjustatble Constant Current Source : 0.5 Amps to 182Amps in 3 ranges at open circuit voltage of more than 30volt – 3 Nos.
Specially designed true RMS sensing current controller maintains current with the help of stepper motor within +/- 1% throughout the range.
Micro controller based Sequential Timer maintains the sequence of operations and displays the test status.
Digital Temperature Indicator min 28 channels with minimum 28 Nos. Thermocouple bid, Teflon insulated will be provided.
Overall accuracy : 1.0.
Digital Milivolt Meter with 3 ranges is provided for measurement of watt loss (Voltage Drop).
Inductors with tapping for each range will be provided for maintaining the open circuit voltage to 30V. This eliminates energy wastage during test.
Forced cooling will be provided by means of an Exhaust fan to remove the hot air generated inside the panel cabinet.
The entire system will be housed in sturdy M.S. Cabinet (trolley) duly powder coated.
The test bench can be customized as per the rated current range of the RCBOs (typically upto 63 A and upto 125 A). Additionally, The bench can be made to test MCBs also. Further customizing options are micro-controller based / PC based with fully automatic seection and testing plus report generation. The equipment can be clubbed with temperature rise + power loss test bench.
The product is used to conduct 28 days test as per the standards.
