ZERO VOLTAGE SWITCH
DESCRIPTION
The UTC A2804 is a TRIAC controller providing a complete
solution for temperature controlled electric panel heaters, cookers
film processing baths etc.
Switching occurs at the zero voltage point in order to minimize
radio frequency interference. The device is suitable for mains-on-line
operation and requires minimal components.
FEATURES
*Easy operation either through the AC line or a DC supply.
*Supply voltage control.
*Very few external components.
*Symmetrical burst control-No DC current components in the load circuit
*Negative output current pulse up to 250mA-short circuit protection.
*Reference voltage output |
