Industrial ET3500 Transformer

The Rathgeber ET-3500-CNA Voltage Transformer delivers a robust 3,000 VA rating, taking a 575 V AC input and providing a 36–44 V AC output for downstream devices. Identified as ET-3500-CNA and cataloged under B439680, this unit belongs to Rathgeber's ET3500 family and is designed for industrial power systems needing isolation and a stable low-voltage supply from a high-voltage source. With a 575 V primary and 36–44 V secondary, it enables safe operation of relays, meters, and low-voltage controls drawn from a 575 V feed, making it suitable for panel installations, automation setups, and testing environments that require a controlled 36–44 V AC supply. The ET-3500-CNA's high-VA rating supports sustained loads and multiple devices connected to the secondary within its nominal range, helping to simplify distribution architectures in facilities that standardize on high-voltage sources while utilizing common 36–44 V devices.
