Siemens 6EV1352-5BK00 Power Supply

This power supply unit converts AC mains into stable 24V DC output. The Siemens 6EV1352-5BK00 belongs to the SITOP power supply family. You can mount this unit on standard DIN rails inside control cabinets. Its rugged design supports continuous operation in demanding industrial environments.

Physical Dimensions and Mounting Configuration

The Siemens 6EV1352-5BK00 measures 7.2 cm in overall width. Its total depth reaches 12.5 cm including terminal covers. This power supply weighs approximately 0.85 kg. A metal enclosure provides excellent heat dissipation and shielding. Four clips secure the unit to a 35 mm DIN rail. A green LED indicates proper output voltage presence.

Input and Output Specifications

This unit accepts 85 to 264V AC input voltage automatically. The Siemens 6EV1352-5BK00 also operates on 110 to 300V DC input. The module delivers 24V DC at 5.0A continuously. Output power reaches 120W under normal operating conditions. Built‑in overload protection shuts down the unit during short circuits. Furthermore, the module resumes operation automatically after fault removal.

Energy Storage and Hold‑Up Performance

A 560 µF capacitor bank stores energy for brief power interruptions. The Siemens 6EV1352-5BK00 provides 20 ms of hold‑up time at full load. This storage allows the CPU to complete critical operations safely. Consequently, system shutdowns occur gracefully rather than abruptly.

Protection Circuits and Diagnostic Features

Overload protection activates when output current exceeds 6.0A. Short circuit protection responds within 30 µs of fault detection. The green DC OK LED confirms proper output voltage presence. Therefore, maintenance personnel can verify power status at a glance. Overvoltage protection clamps the output at 28V maximum.

Installation and Wiring Guidelines

Clip the unit onto a 35 mm DIN rail until it clicks. The Siemens 6EV1352-5BK00 accepts solid or stranded wires from 0.5 to 2.5 mm². Connect the AC input wires to the three‑pin terminal block. Route DC output wires separately from AC input cables. This separation reduces electrical noise on the 24V DC bus.
