ABB 3KDE175132L9100 Power Supply Unit

This power supply unit provides stable DC power for ABB industrial automation systems. It converts 230V AC input to regulated 24V DC output for field devices. Therefore, this component ensures reliable operation of controllers, I/O modules, and sensors.

Physical Dimensions and Weight Specifications

The ABB 3KDE175132L9100 features a rugged metal housing for DIN rail mounting. Its width measures 62 mm for standard industrial enclosures. The total depth reaches 115 mm including the terminal block. Consequently, technicians can install this unit in typical control cabinets.

Interface Types and Connection Layout

The ABB 3KDE175132L9100 provides screw-clamp terminals for AC input wiring. Separate screw terminals deliver 24V DC output to the load circuit. 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 three 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 3KDE175132L9100 stores energy in three 820µF output capacitors. This storage provides a 35 ms hold-up time after AC loss. Therefore, connected devices continue 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 -10°C to 60°C. A built-in fan cools the internal components under heavy loads.
