| Powering Communications and Technology SMS SERIES 12 WATT DESCRIPTION SMS surface-mountable DC/DC converters feature up to 12 Watts of output power. The SMS is a fully isolated converter with 1500 VDC isolation, short circuit, and undervoltage lockout protection. The SMS is available with remote shutdown, as well as an optional active current share, to allow for high power distributed operation. Available in 24 or 48 VDC input versions, the SMS is well suited to telecom and networking applications.
