CCD intelligent composite switch

 

 

Product description

  CCD series composite switches adopt advanced single chip microcomputer software synchronous zero-crossing technology, which not only eliminates the electric arc pre-combustion and re-combustion between the contacts of magnetic latching relay, but also overcomes the difficulty of discreteness of actuation time of magnetic latching relay, so as to ensure the perfect zero-crossing switching of magnetic latching relay. Compared with common composite switch, it is reliable in operation and cost-effective, and the response time ≤20ms.  

 

Product features

   Achievement of zero-crossing switching, input inrush current is ≤ 2 times of rated current, and the extension of the service life of capacitor;  Low power dissipation with a self-power dissipation of ≤ 4VA, and requires no radiator or fan for heat dissipation;  Be provided with lack-phase protection function;  Photoelectric isolation is adopted for input terminal of control signal to achieve isolation of high and low voltage circuits;  抗Be provided with strong anti-interference capability, EFT group impulse test, 4000V A Class (the highest of national standards).  

 

Technical parameters

   Voltage range: 380VAC±20%;  Rated power: 50/60Hz;  Control voltage: 12VDC/10mA;  Contact voltage-endurance: 1600V;  Service life: ≥100,000 times;  Control capacity: common compensation: ≤67kvar separate compensation: ≤3*20kvar.
