DESCRIPTION
The CMSP & CMSPW series consists of single output half brick DC/DC converters on a chassis mount that offer up to 100 watts of
output power in an industry standard package and footprint. It is intended to provide power and isolation for pc board and chassis
mount applications requiring high power density. Some features include wide input voltage ranges, positive or negative remote
on/off, remote sense, output trim, short circuit protection, and over voltage protection. Being encapsulated, these supplies have
improved thermal dissipation and protection for ruggedized environments. All models are 100% burned-in.

NOTES
1. Auto off power train protection.
2. All case, pin to case, and pin to header dimensions reference only unless otherwise noted.
3. 48VDC input with 48VDC output not available in 75 and 100 watt models.
4. Through-hole instead of threaded inserts available (0.125” diameter), add suffix “TH”
5. Positive Remote ON/OFF control is standard. To order negative logic Remote ON/OFF control add the suffix “R” to the part number
(Ex: CMSP48S48-100R).
