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;
