DU & SU Step-Up or Step-Down Transformers

Signal Transformer / Bel DU and SU Industrial Grade Step-Up or Step-Down Transformers allow users to adapt voltages for worldwide applications. The transformers are designed to provide a multitude of step-up or step-down voltage configurations to accommodate various input voltages. The series has a power rating of 250VA to 10kVA and a 2500V_rms hipot dielectric strength. Signal Transformer / Bel DU and SU Transformers feature plated brass screw-type terminals and can be chassis or rack-mounted.
