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 ofup to 305VAC or 430VDC.

It is recommended to additionally bond the /277 version of the converterto 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 remotehandset, the standard 12V relay
can switch a 16A load.
