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;
