April 20, 2015 - MicroPower Direct introduces MPU-250S AC/DC power supplies. The 250W AC/DC power supplies are packaged in a compact 5 x 3.2 inch U-Channel.
Four standard models operate from autoranging inputs of 90 to 132 VAC or 180 to 264 VAC, providing tightly regulated single outputs. Outputs are factory set to 12, 15, 24, or 36 VDC. Standard features include FCC class B emissions, power factor correction to EN 61000-3-2 A, I/O isolation of 3,000 VAC, and 20 mS hold-up time. All models are protected for over temperature, over load, over voltage & short circuit faults. Interface signals for Power On and Power Good are provided, as well as a driver output for an external fan.
The MTBF (per MIL HDBK 217F) of the MPU-250S series is greater than 100 khours. All models are approved to EN 60950.
The MPU-250S family is packaged in a compact 5 x 3.2 x 1.5 inch U-Chassis. With only 16 CFM airflow, they provide 250W of output power. This supply is also available with a “finger safe” cover or with a top-mount fan.
Each model is specified for operation over the wide operating temperature range of 0°C to +70°C (ambient).
