A2804 - ZERO VOLTAGE SWITCH

General 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.

Key Features

  • S.
  • 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.
