Description
Composite switch HYFK series composite switch uses thyristor switch and magnetic holding switch to run in parallel. It has the advantages of thyristor zero-crossing switching at the moment of switching on and off, and has the advantages of zero power consumption of magnetic holding switch during normal switching on.
Composite switch HYFK has the obvious advantages of no shock, low power consumption, long service life, etc.
Features:
- Built-in microprocessor and intelligent software, can intelligently control
capacitor switching - The product achieves zero crossing switching, no arc, no inrush current,
fast response - On-resistance is zero, no harmonics are generated
- No switching inrush current, no current limiting reactor required, reducing the cost of the complete cabinet
- Non-heating, can be installed in a closed box
- Micro power consumption, less than 1% of contactor power consumptionSimple structure, easy installation and lower cost than thyristor switchesLow failure rate and much longer service life than thyristor and contactorsExtended operating temperature range
