RX9527 relay on-off capability life test device

1. Overview:

RX9527 series, relay connection and disconnection capacity, electrical life test equipment (hereinafter referred to as 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 test equipment:

2.1. Sample coil working voltage:

2.1.1. DC voltage regulation: DC3~30V 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;

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

2.4.2, load is switched by knife switch

2.4.3, load cooling 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, product power on and off with indicator light

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 number of failures: 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 final test count of the fault failure station.

2.8. The equipment has protection and alarm functions for welding, short circuit and other phenomena of the test sample.

2.9. The load box is set with high test temperature alarm, overcurrent protection, and AC leakage protection functions.

2.10. Controller: uses intelligent timer and counter, all data is saved when power is off

2.11. Power supply of equipment: AC220V 50/60Hz 20KVA

2.12. Approximate size of equipment: 1800mm wide x 900mm deep x 1800mm high, weighs about 700kg
