Pioneer Magnetics PM3398B-6-1-3-E AC-DC Power Supply

The Pioneer Magnetics PM3398B-6-1-3-E (order number 80026-172-24) is a robust AC-DC power supply designed for industrial automation, process control, and telecommunications. It converts universal AC input (90-264V, 47-63Hz) to a regulated 24V DC output with 6A continuous current (144W). The unit features active power factor correction (PFC), high efficiency, and a rugged enclosure suitable for harsh environments.

Construction and Cooling

The power supply is housed in a ventilated metal case with integrated fan (temperature-controlled). For operation in dusty environments, a fanless version is available by special order. The unit includes screw-type input and output terminals for secure wiring. A green LED indicates output status, and a red LED signals fault conditions.

Protection Features

Comprehensive protection includes: output overvoltage protection (crowbar at 28V), overcurrent limiting with constant current mode, short-circuit protection with automatic recovery, and thermal shutdown with hysteresis. The power supply also features input surge protection (MOV) and EMI filtering to meet EN 55022 Class B.

Application Domains

This power supply is ideal for PLC power, sensor networks, industrial control panels, and test equipment. Its wide input voltage range makes it suitable for global use, and the extended temperature range allows installation in outdoor enclosures or unheated factories.
