DESCRIPTION

The SBU350 series of ITE open frame power supplies provide 12v, 24v, 36v, and 48v output voltage (VDC) with a power rating of 350W at efficiencies up to 95%. With a universal input of 90 to 264 VAC and complete protection design, the series is designed for ITE and 1U applications that can be applied to industrial PC, av equipment, communication equipment, etc.

The SBU350 series is a Class 1 ITE power supply owning overload protection (OLP), overvoltage protection (OVP), over-temperature protection (OTP), short circuit protection (SCP), high ESD immunity, enhanced no-load performance and a wide operating temperature of -40 to +70°C.

The series conforms to major international safety standards including UL/IEC/EN/CSA C22.2 62368-1, etc., and is fully compliant with RoHS directive. All models meet FCC Part-15, AS/NZS CISPR 32 and EN55032, BS EN55032 class B emission limits, EN55035, BS EN55035 and are designed to comply with UL/cUL, TUV T-mark and conformity assessment in CE marking. All units pass burn-in test at full load condition.
