MicroPower Direct's MPU-240S series power-factor-corrected ac-dc power supply

Compact PFC AC-DC Supplies Meet Industrial Needs

MicroPower Direct’s power-factor-corrected MPU-240S series features 4000-V ac I/O isolation and 20-ms hold-up time.

MicroPower Direct’s MPU-240S series features a range of compact, high performance ac-dc power supplies. The company claims these power supplies have been specifically designed to provide the robust performance, high power density, safety approvals, and compact size required by a wide range of applications in a variety of industries. Eight standard models operate from universal inputs of 90 to 264 V ac, providing tightly regulated single outputs. Outputs are factory set to 5, 12, 15, 24, 28, 32, 38, or 48 Vdc.

Standard features of the MPU-240S series include EN 55032 class B emissions, power factor correction, 4000-V ac I/O isolation (5656 Vdc), and 20-ms hold-up time (with cover). All models are protected for overload, overvoltage, and short-circuit faults. MTBF is greater than 50 hours (per MIL HDBK 217F). All models are approved to UL 60950.

The MPU-240S family is packaged in a compact 6- x 4.18- x 1.38-in. U-chassis. Three I/O connector types are available for all models: terminal blocks, Molex, or clamp blocks. They are also available with a finger safe cover. Each model is specified for operation over a wide operating temperature range of 0°C to +70°C (ambient), says the company.

The model line-up is as follows:
