24V DC Output 50A/60A Current Rating 400V 3-Phase Input Safety Transformer Protection Class I High Current Capacity

Product description

The Siemens 4AV3500-2FB00-0A is a three-phase safety transformer designed as a high-capacity power supply. It operates with a primary voltage of 400V (+/-20% tolerance) at 50/60Hz. The unit delivers a substantial 24V DC secondary output voltage, capable of providing 50A continuously or 60A at 40°C ambient temperature.

This transformer is engineered for rigorous industrial environments and applications requiring significant 24V DC power, such as large-scale automation systems, complex machinery, and high-current control systems. It conforms to safety standards EN 61558-2-6 and EN 61131-2, featuring Protection Class I. Installation is facilitated by its screw connection terminals and screw mounting capabilities.

Stanlo Automation, a veteran-owned surplus industrial parts distributor, offers the Siemens 4AV3500-2FB00-0A. We are dedicated to providing quality automation components and reliable service to ensure your operational continuity.
