Core Advantages

Optimized for S7-200 SMART Systems
The PM207 is designed to match the SIMATIC S7-200 SMART micro-PLC in both design and function. Its slim form factor (45 mm width) is particularly suited for shallow control cabinet depths, making it an ideal companion for space-constrained installations .

Wide Input Voltage Range with AC/DC Flexibility
The power supply accepts 85–264V AC or 88–370V DC input, providing flexibility for diverse industrial power architectures. This wide range simplifies integration into different regional power systems and supports DC-backed applications .

Adjustable Output Voltage
The 24V DC output is adjustable from 22.8V to 26.4V via a front-panel potentiometer, allowing compensation for voltage drops in long cable runs or optimization for specific load requirements .

Parallel Configuration Capability
Up to two PM207 3A units can be connected in parallel for capacity expansion, providing a scalable power solution as system requirements grow .

Compact and Efficient
With approximately 89% efficiency and a slim 45mm profile, the PM207 minimizes energy loss and panel space consumption. The unit includes electronic short-circuit protection with automatic restart .

Suitable for ST and SR CPU Variants
The PM207 is required for ST-series CPUs (which are DC24V powered) and can be used as an optional supplementary supply for SR-series CPUs (which are AC220V powered and include onboard sensor supply) .
