IEC60947-4-1 AC Contactor Life Test Device
Application:
The equipment is used to test the action characteristics of AC contactors and detect the overrun, synchronization error, total stroke, current and voltage of AC contactors.
Standards:
- IEC60947-4-1-2000
- IEC60947-1-1999
Technical parameters:
1. Can conduct electrical life test on single-phase ac contactor contacts;
2. 5 station work at the same time, at the same time in the same load according to the set sequence, set a time with the same load successively connected or breaking, such as N1 breaking load moment N2 samples from off state immediately (switch time delay maximum 0.5 1 second) into connected with load, N1 - N5 so on circulation, five station test data independent random setting and display;
3. Count the number of on-off test at each station. When any test sample fails (normally open or normally closed), the system will automatically disconnect the load and coil control voltage of the failed sample, without affecting the normal test of other samples.
4. The on-off and on-off time can be set as needed. The time resolution is 0.01 seconds.
5. The number of trials can be preset arbitrarily, and the counting range of trials is 0 ~ 9999999 times;
6. Continuously adjustable load current 0 ~ 100A;
7. Voltage :0 ~ 250V continuously adjustable;
8. Power factor :0.3 ~ 1 continuously adjustable;
9. Display parameters: digital display output voltage value, current value, power, power factor;
10, Coil voltage is ac 24V, 48V, 120V, 220V gear adjustable;
11. The equipment ADAPTS to the working environment temperature: 0 -- 40℃, relative humidity: < 80%;
12. The load box is equipped with the functions of excessive test temperature alarm, power failure protection, overcurrent protection and leakage protection;
13. All test data are designed with power failure protection function;
14. The measuring range of the ambient temperature is 2-51 ° C, the resolution is 0.01 ° C, the accuracy is 1% and 0.2 ° C;
15. The insulation and safety of electrical equipment must meet the requirements of relevant national standards;
16.Working environment
1) Indoor use, and indoor ventilation is good;
2) The altitude is no more than 2000m;
3) The daily average relative humidity is not more than 95%, and the monthly average relative humidity is not more than 90%;
4) No strong vibration or shock;
5) There is no serious dust, explosive dangerous media, harmful gases that corrode metals and destroy insulation, conductive particles and serious mold;
