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.

Notes
†
MTBF predictions may vary slightly from model to model.
Specifications typically at 25°C, normal line, and full load, unless
otherwise stated.
Soldering Conditions: I/O pins, 260°C, ten seconds; fully compatible with commercial wave-soldering equipment.
Safety: Agency approvals may vary from model to model.
Please consult factory for specific model information.Units are
water-washable and fully compatible with commercial spray or
immersion post wave-solder washing equipment.
