SIEMENS 6EP7133-6AE00-0BN0 SIMATIC ET 200SP Stabilized Power Supply

Overview

The SIEMENS 6EP7133-6AE00-0BN0 is a regulated 24 V DC power supply designed specifically for the SIMATIC ET 200SP distributed I/O system. The SIEMENS 6EP7133-6AE00-0BN0 accepts single-phase AC input and delivers a stable 24 V DC, 10 A output to power ET 200SP base units, I/O modules, sensors and field actuators. The SIEMENS 6EP7133-6AE00-0BN0 features automatic voltage range adaptation and built‑in diagnostic signaling contact, widely used in factory automation, packaging machinery, process skids and material handling control cabinets. It is an active original Siemens spare unit for ET200SP station expansion and replacement.

Features

The SIEMENS 6EP7133-6AE00-0BN0 supports two AC input ranges: 85–132 V AC and 170–264 V AC with automatic switching for global 50/60 Hz grids. The SIEMENS 6EP7133-6AE00-0BN0 provides adjustable DC output voltage (22.8–28 V) to compensate for long cable voltage drop. It includes short‑circuit protection, overload protection and a minimum 20 ms hold‑up time upon mains failure. The SIEMENS 6EP7133-6AE00-0BN0 has a green status LED and a potential‑free signaling contact to send “24V OK” status to PLC and SCADA. Up to two units of the SIEMENS 6EP7133-6AE00-0BN0 can be paralleled for higher power demand. It is suitable for Zone 2 hazardous area applications and adopts standard DIN rail mounting.

Specs

Device Type: Regulated DC Power Supply Model: SIEMENS 6EP7133-6AE00-0BN0 Series: SIMATIC ET 200SP PS Input: 1-phase AC, 85–132 V / 170–264 V, 50/60 Hz Output: 24 V DC, 10 A Adjustable Output Range: 22.8 V – 28 V Hold‑up Time: ≥20 ms at rated load Protection: Short circuit, overload Diagnostics: Status LED, isolated signaling contact Mounting: DIN rail Dimensions: 160 × 117 × 66.5 mm Weight: Approx. 0.72 kg Operating Temperature: -30°C ~ +60°C (derating above 60°C) Certification: Suitable for Zone 2 hazardous location

Principle

The SIEMENS 6EP7133-6AE00-0BN0 converts single‑phase alternating current into galvanically isolated, stabilized 24 V direct current via high‑frequency switching topology. The internal control loop maintains constant output voltage under load variation. When output voltage drops below threshold due to overload or input loss, the status contact opens and the LED extinguishes to notify the control system. The built‑in buffer circuit keeps 24V output alive for a short period during brief mains interruption.

Applications

The SIEMENS 6EP7133-6AE00-0BN0 supplies power to SIMATIC ET 200SP remote I/O stations in production lines, water treatment skids, conveyor systems and packaging automation. The SIEMENS 6EP7133-6AE00-0BN0 is stocked as spare part for emergency replacement and scheduled cabinet maintenance of ET200SP stations. It also supports distributed I/O cabinet expansion and power capacity upgrade projects.
