P OWE R T RAN S FO R M E R CHASSIS MOUNT : Autotransformer F-302U Electrical Specifications (@25ºC) 1. Maximum Power: 150 VA 2. Input Voltage: 277 V, 60 Hz only 3. Output Voltage 115V, + 5% at full load 4. Full Secondary Load 1.3 Amps RMS Construction: Single winding on a double wall, nylon bobbin. Three leads exit the transformer, the black lead is the tap. RED WH T Safety: These units are designed with 1500V isolation between the winding and the core. Materials and construction are rated for Class B insulation system. BLK Description: Secondary coil is a fraction of the entire winding for voltage step-down. This causes part of the power to be transferred conductively through the windings, rather than all of the power being transferred by induction.
