ABB 3HAB5845-1/1 Power Supply

This power supply provides DC power for ABB industrial robot control systems. It converts AC line voltage to regulated outputs for controller modules. Therefore, this component ensures stable operation of robotic automation equipment.

Physical Dimensions and Weight Specifications

The ABB 3HAB5845-1/1 features a rugged metal housing for heat dissipation. Its width measures 110 mm for standard cabinet mounting. The total depth reaches 200 mm including the terminal block. Consequently, technicians can install this unit in robot controller cabinets.

Interface Types and Connection Layout

The ABB 3HAB5845-1/1 provides screw-clamp terminals for AC input wiring. Separate screw terminals deliver DC output to the controller backplane. The front panel carries a green LED for output status indication. Hence, operators can verify power availability at a quick glance.

Component Count and Internal Architecture

This power supply contains one main board with a switching regulator circuit. The board holds four large electrolytic capacitors for output filtering. You will also find a bridge rectifier and a ferrite transformer. An onboard fuse protects the unit from overcurrent events.

Energy Storage and Hold-Up Time

The ABB 3HAB5845-1/1 stores energy in four 1500µF output capacitors. This storage provides a 25 ms hold-up time after AC loss. Therefore, the robot controller continues operating during brief power interruptions. The unit requires no external battery for this function.

Protection Features and Operating Range

The power supply includes short-circuit and overvoltage protection. It also features overtemperature shutdown with automatic recovery. Users can operate this unit in temperatures from 0°C to 50°C. A built-in fan cools the internal components under heavy loads.
