Specifications
1.More than 10 years exporting experience2.Replace with contactor switching time<1000ms
2.Economic type
3.Easy installation
No swithing surge current, low looss, no noise, good stability, nice reliability
It include 3 pcs of independent combination switches, is suitable for switching on /off the low
voltage reactive power compensating capacitor bank. The working theory is that it s contro llable silicon shunt connected with magnetic positioned relay, this will realize that the switching device make or break the capacitor at the moment of ratings through zero via
controllable silicon, and during closing it does not have power loss same as contactor.
1. Switch under zero rating
2. Chipset used for switching on/off and intelligently monitor the controllable silicon, magnetic positioned relay and input power source and load running status, has complete protection functions.
3. No harmonic wave input
4. Low loss
Technical Parameters:
1. rated working voltage 380V 220V/AC 20%
2. rated frequency 50Hz 5
3. controlled capacity ( three phases 30Kvar Delta connection) (single phase 10Kvar Y Star connection)
4. circuit loss 1.5VA
5. outline dimension 126mm 156mm 128mm
6. interval between each switching on/off 1s
7. Interval between two operations of switching on: > 100s (NB: when switch device is just energized or closed after opening, it shall delay 100s (fixed)
8. starting voltage DC 8-18V
9. distortion rate of voltage 5%
10. working life 100,000 times / 100 thousand times
11. response time 1000ms
12. closing resistance 0.003
13. fixed size 77mm 138mm
14. input resistance 5.1K
15. working power source voltage 220V
16. max rated current 45A
17. voltage drop on contact 100mV
18. withstand voltage of contact 1600V
