RAC04
Description
The RAC04 series is an ultra-compact universal input
AC/DC power module for PCB mounting.
It features ultralow no-load power consumption, short
circuit, overload and output overvoltage protection as
well as a built-in EMC Class B filter. A high input
voltage version (suffix /277) is also available for input
voltages of up to 305VAC or 430VDC.

It is recommended to additionally bond the /277 version of the converter
to the PCB if the application is subject to vibration or mechanical shock.
Standard Application Circuit
Standby Relay Application
With 110VAC supply and 10mA
standby load, the circuit
consumes typically only 150mW.
Once activated by the remote
handset, the standard 12V relay
can switch a 16A load.
