UTC A2804 LINEAR INTEGRATED CIRCUIT 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 *Pb-free plating product number: A2804L PIN CONFIGURATION REF.
