www.elma.com DATA SHEET HOLD-UP BOARD
DESCRIPTION
In normal operation, the input voltage will feed thru to the PSU and the hold-up capacitors will be charged. In case of a voltage drop of the input voltage, the input voltage will be disconnected and the PSU will be supplied by the hold-up capacitors. MECHANICAL DETAILS The Hold Up board is available as a fixed mounted and a plugged version. For conducted cooled chassis, additional wedge locks can be mounted. Mating connectors Fixed mounted version: FCT FL21WA4S7-K121 Pluggable version (PCB): FCT FM21WA4P22-1277 Part numbers Hold-Up Module PCB only w/o cover: 055-149 Hold-Up Module with additional cover: 064-474
