DESCRIPTION

The SPU31 series of ITE desktop power supplies (external power adapters) provide 12v, 24v, 36v, and 48v output voltage (VDC) with a power rating of 20W-30W at efficiencies up to 83%. With a universal input of 90 to 264 VAC and complete protection designs.

The series is a Class I ITE power supply that can be used in the temperature range of 0 to +70°C and is certified to EN/EMC/CSA C22.2/IEC 60950 standards. All models are fully compliant with RoHS directive. They meet FCC Part-15 class B and CISPR-32 class B emission limits and are designed to comply with UL/c-UL and CE marking conformity assessment. All units pass burn-in test at full load condition.

The series features an efficiency level V and can be used in high-altitude applications. It is ideal for ITE applications that can be applied to measuring instruments, chargers, monitors, set-top boxes, etc.
