CMMMW

The CMMMW series of chassis mount DC/DC converters offers up to 30 watts of output power. These converters operate over 4:1 input voltage ranges of 10-40VDC and 18-75VDC. This series also provides regulated single outputs of 3.3, 5, 12, and 15VDC. Other features include remote on/off control, output trim function, and efficiencies up to 89%. All models are over voltage, over temperature and short circuit protected. The EN55022 Class A conducted noise compliance minimizes design time, cost, and eliminates the need for external filter components. These converters are best suited for data communication equipment, mobile battery driven equipment, distributed power systems, telecommunications equipment, mixed analog/digital subsystems, process/machine control equipment, computer peripheral systems, and industrial robot systems. Chassis mounts come in open frame, U channel, and enclosed types.

Notes & safety
Notes: 1. Transient recovery time is measured to within 1% error band for a step change in output load of 75% to 100%.
2. The CMMMW series requires a minimum output loading to maintain specified regulations. Operation under no-load conditions will not damage these devices, however they may not meet all listed specifications.
3. Other input and output voltages may be available, please contact factory.
4. Heatsink is optional. Please consult factory for ordering details.
5. Chassis Mount Options: No suffix for open frame, “U” suffix for U Channel, and “E” suffix for Enclosed type.
Due to advances in technology, specifications are subject to change without notice.
