product overview

The model is a high-performance AC-DC power module for ABB’s industrial automation field,designed specifically for communication equipment,industrial control,and high reliability scenarios.Its core function is to convert AC power into stable DC power,support high-precision output and wide range input voltage,have high isolation voltage and compact structure,suitable for scenarios such as program-controlled switches,mobile base stations,and automated production lines,ensuring stable operation of equipment in complex environments.

Main features and advantages

High reliability and stability

Adopting industrial grade components and redundant design,it supports long-term continuous operation with a failure rate of less than 0.1%(typical value),suitable for communication base stations and industrial equipment that operate continuously for 24 hours.

Isolation voltage above 3000V(AC-DC type)effectively suppresses electromagnetic interference and ensures system safety.

Flexible input and output configuration

Supports a wide input voltage range(such as 85-264 V AC)to adapt to different power grid environments.

The output voltage can be customized(such as 12V,24V DC)to meet the diverse needs of communication equipment,sensors,and actuators.

Efficient and energy-saving design

The conversion efficiency is over 90%,reducing energy loss and meeting green industry standards.

Low idle power consumption design,extending device standby time.

Compact structure and compatibility

Compact size(approximately 100×50×30 mm),supports standard rail installation,and is easy to integrate into cabinets or equipment interiors.

Compatible with other ABB power modules(such as PFCL201CE 10KN),it can be extended to multiple power supply systems.
