Hold-Up and Hold-Up Light Modules
These modules provide the user with uninterrupted power during brownouts, transients and glitches. Calex has developed two versions of this mission critical component – the Hold-Up module with everything built into a “use as is” package and the space-optimized Hold-Up Light with user programmable hold-up time.
Key features of the Hold-Up (HU-28) module:
- ½ brick package (2.28” x 2.4” x 0.50”)
- 50ms hold-up time without external capacitors
- User programmable under-voltage trip: 13.5V to 22V
- Trip status indicator
- All ceramic solution
- Excellent MTBF
