Murata Power Solutions has announced the MVAB120 series of high efficiency, typically up to 91%, open frame single output 120 Watt power supplies aimed at a broad range of telecom and industrial applications. Measuring just 101.6 x 50.8 x 34.3 mm (2 x 4 x 1.35 inches), the low profile units satisfy the 1U height constraints of this industry standard footprint.
The high efficiency design of the MVAB120 ensures that waste heat is kept to a minimum and the units are capable of delivering up to 75 W using convection cooling only. Just 250 LFM forced airflow is required for the supply to operate at the 120 W full load output.
The series comprises three single output models covering the nominal outputs of 12, 24 or 48 VDC. Accommodating the full universal range of input voltages, from 90 – 264 VAC and 120 – 300 VDC, the MVAB120 also meets the EU PFC directive for active power factor correction. Safety approvals include the internationally recognized UL/EN/IEC 60950-1:2005 2nd edition standard for IT and commercial equipment. The units also comply with IEC/EN 61000 Class A and EN55022 Class B standards for emissions and immunity.
Suiting most operating environments, the MVAB120 series can deliver full load from -10 to + 50 degrees C, and is capable of start-up from temperatures as low as -20 degrees C.
Output protection features include overcurrent, overvoltage and overtemperature.
