DESCRIPTION

The SBU31 series of ITE open frame power supplies offer 9v 3a, 30v 1a, and other model selections that are available for voltage levels of 5v-48v with 20W-30W output power with a universal AC input of 90 to 264 VAC at a typical efficiency of greater than 80%.

The SBU31 series is a Class 1 ITE power supply that owns an EMI filter, overvoltage protection (OVP), overload protection (OLP) and conforms to major international safety standards, including CSA C22.2/EN/IEC/UL 60950-1, etc., and is fully compliant with RoHS directive. All models are designed to comply with UL/c-UL marking conformity assessment and pass burn-in test at full load condition.

With a full protection design and low voltage ripple, the series is suitable for ITE equipment/devices such as ATM machines, commercial refrigerators/freezers, CCD recorders, etc.
