Relay life test bench The relay on-off performance test bench is mainly used for comprehensive performance testing such as relay on-off performance and life testing
Structural components: resistance cabinet, inductance cabinet, control cabinet, adjustable frequency conversion power supply
The working principle is to set the coil working mode (AC/DC) test times, on-off time, cumulative failure times and other parameters, adjust the coil voltage (AC/DC), press the start button to start the test, and the test sequence is fixed from the first station (full station selection). After one cycle of on-off (single station cycle) and a delay of 0.5-1S (station switching time can be set), the second station detection is started, and so on until the sixth station. After one cycle of on-off at the sixth station, the test cycle starts again from the first station. If one station fails in the middle (such as the third station), the test will bypass this station and continue with the following experiments (from the original 1-2-3-4-5-6 cycle to the original 1-2-3-4-5-6 cycle). -1-2-4-5-6 cycle), 5.

The number of tests at the workstation has reached, and the test has stopped.
Main technical parameters:
Current: 3-10A, accuracy 2%
Power factor: 0.3-1 accuracy ± 0.05
Minimum resolution for on/off time: 0.1S
Test relay coil control voltage: Voltage: DC3-50V, AC: 3V-300V
Coil current DC: 800mA, AC: 1A
Test times: Maximum of 9999999 times (can be set arbitrarily)
Equipped with emergency stop switch: In case of emergency, press it to cut off the power supply of the main load circuit
Electricity meter: displays load voltage, current, and power factor
Screen display function: The required number of tests and on/off time can be set on the touch screen, and the test data can be maintained or queried
Data recording method: Equipped with RAM with battery protection, it can store the device's set values, sampling values, and sampling time, with a maximum memory storage of no less than 30 days of historical curves and data (when sampled for 1 minute)
Alarm indication: When there is an abnormality in the equipment and sample, an audible and visual alarm will be issued, and the fault location, cause, and solution will be displayed on the instrument
