Physical Dimensions and Component Layout

This unit measures 12.0 cm in length and 12.0 cm in width. Its total height reaches 8.5 cm including the heat sink. 3KDE175133L9100 weighs 1.8 kg for DIN rail mounting. You will find 86 discrete components on a two-layer PCB.

Moreover, the unit integrates a 1500 µF output capacitor bank. This bank stores energy for a 30 ms hold-up time. It also filters switching noise from the power converter.

Power Conversion Topology

A step-down switching regulator performs the AC-DC conversion efficiently. This topology achieves 90% efficiency across most load ranges. The design uses active power factor correction for reduced harmonics. Consequently, the unit generates minimal heat during normal operation.

Protection Features and Diagnostics

Overload protection limits output current to 12A continuously. Short-circuit protection automatically resets after fault removal. Overvoltage protection shuts down the output above 28V. A green LED indicator shows output voltage present and stable.

Connector Interface and Installation

A 3-pin terminal block accepts 100-240V AC input wiring. A separate 4-pin terminal block delivers 24V DC output. The unit clips directly onto standard 35mm DIN rail. You can mount the unit in any orientation for cabinet flexibility.

Typical Application Scenarios

You can deploy 3KDE175133L9100 in PLC control panels and industrial automation cabinets. It also works well for powering sensors, relays, and small drives. This unit supplies clean 24V DC power to I/O modules. Its 10A capacity suits medium-sized control systems.
