Step-Up/Step-Down Power Isolation Transformers – SU/DU Series

Signal Transformer's SU and DU transformers have been designed to provide a multitude of step-up or step-down voltages to accommodate various input voltages available throughout the world. Primary input voltage can be configured to accept ratings from 104 V_AC to 240 V_AC with a variable user selectable output voltage rating from 208 V_AC to 240 V_AC on the secondary windings. Durable construction allows the SU and DU series to be either mounted on a chassis or a rack, with power ratings from 250 VA to 10 kVA the brass plated screws and terminal materials offering the best possible power transfer from transformer to the equipment, limiting heat generation.
