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

DIP-8

SOP-8

*Pb-free plating product number: A2804L
