RX9528 relay on/off capability life test equipment

1. Overview:

RX9528 relay switching capacity life test equipment is designed according to the relevant requirements of GB14598.1-2001 and GB7261-2008 "Basic Test Methods for Relay Protection and Safety Automatic Devices".

2. Main technical parameters of the test equipment:

2.1. Working voltage of sample coil:

2.1.1. DC voltage regulation: DC3~110V adjustable Display accuracy: ±1% reading ±2 words.

2.1.2, AC: AC0~250V adjustable, display accuracy: ±1% reading ±2 characters

2.2, test station: 1~6 stations can be set, cycle work, share a set of loads

2.3, sample contact rated current: 1~10A

2.3.1, test voltage (AC/DC): no-load voltage 0~300V adjustable, display accuracy: ±1% reading ±2 characters

Load voltage does not exceed 280V

2.3.2, load current: 1~60A adjustable, current display accuracy: ±1% reading ±2 characters

2.3.3, power factor: 0.3~1, display accuracy: ±0.03

At the moment of coil power on, it is 6 times the rated current within 100mS, and then it drops to 1 times the rated current

2.4, the load is composed of multiple inductors and resistors in series, and the load can be converted between AC and DC;

Load resistance: 0.025～300Ω adjustable, minimum step value is 0.025Ω

Load is switched by knife switch

Load heat dissipation method is forced air cooling, and its working system is long-term continuous working system.

2.5. Load working mode: pure resistance load, inductive load, motor load can be selected

2.6. Operating frequency:

2.6.1. Power-on time: 0～99.99s Accuracy: ±1%;

2.6.2. Power-off time: 0～99.99s Accuracy: ±1%.

2.6.3. The product has an indicator light to indicate power on and off

2.7. Test number range: 1-999999 times can be set; accuracy: ±1 time.

2.7.1. Maximum number of failures: 1 to 9999 times can be set

2.7.2. First failure number: 1 to 999999 times can be recorded

2.7.3. When any test sample fails (normally open or normally closed), the number of failures increases by one; when the set number of failures is reached, the system automatically disconnects the load and coil control voltage of the failed sample, and the system retains the count of the final test number of the fault failure station and records the position of each failure (up to 50 failures can be recorded for each station).
