ABB 1MRK002239-BBR03 Power Supply Module

Description

ABB 1MRK002239-BBR03 Power Supply Module is an industrial-grade power module designed for reliable operation in harsh industrial environments. It features core functions including voltage conversion and regulated output, converting AC or DC input voltages to stable DC output voltages to ensure consistent system performance. The module supports multi-channel output, enabling power supply to multiple subsystems simultaneously for integrated power management. It is equipped with comprehensive system protection functions such as overvoltage, overcurrent, and short-circuit protection, which significantly enhance operational safety and stability. Additionally, it supports power supply status monitoring, outputting working status signals for system self-diagnosis and alarm triggering.

This module is suitable for a range of critical industrial applications, including digital substation systems where it powers intelligent electronic devices, merging units, and remote terminals; it also serves as a power source for the core protection control circuits of ABB REL670, REF615, and RET670 series relay protection devices, and supports stable operation of control and monitoring systems such as SCADA, human-machine interfaces, and data acquisition modules. Like other ABB industrial power modules, it offers high operating frequency ranging from 300KHz to 1MHz, compact size with thickness below 20mm, weight under 200g, and high power density of 5 to 10W per cubic centimeter. It has a wide input voltage range of 150V to 280V AC, broad temperature adaptation from -55 degrees Celsius to 100 degrees Celsius, fully sealed packaging with waterproof, dustproof, and impact-resistant properties, and excellent electromagnetic compatibility via zero voltage or zero current switch technology.
