ABB 3BHB016295R0001

Product Overview

ABB 3BHB016295R0001 is a compact and high-performance DC/DC converter produced by ABB. The model MINI-PS-12-24DC/24DC/1 clearly describes its core function as an isolated switching power supply with an input voltage range of 12-24V DC, an output voltage of 24V DC, and a rated output current of 1A. This product is mainly used to provide reliable power supply for sensors, small actuators, PLC modules, relay coils, or other low-voltage electronic devices that require a stable 24V DC power supply in industrial control systems. Its compact size and sturdy design make it highly suitable for installation in control cabinets with limited space.

Use Case

Power Supply Upgrade for Sensors in an Old Production Line

A stamping production line at an automotive component factory has been in operation for over 15 years. Recently, the inductive proximity switches used to detect the arrival of workpieces frequently gave false alarms, causing unplanned downtime of the production line. Engineer Wang inspected the situation and found that these sensors were powered by an aging 24V DC centralized power supply bus. Due to the long length of the line and the thin diameter of the wire, along with the impact from the startup of other equipment, the voltage at the end of the bus often dropped below 20V, which was below the minimum voltage requirement for the sensors to operate normally.

Replacing the entire power supply cable was costly and required a long production halt. Wang proposed a clever solution. Near each installation location of the proximity switch, an ABB 3BHB016295R0001 micro DC/DC power supply was installed. He used the already available and more stable 24V main control power supply as the input for this micro power supply.

After the renovation was completed, each proximity switch received a stable and pure 24V local power supply. Even if there was a slight fluctuation in the main power supply bus, it would not affect the operation of the sensors. The failure rate of the production line significantly decreased, and this low-cost, high-efficiency renovation was highly praised by the factory management.
