The T181064 is a versatile buck-boost transformer designed for single-phase and three-phase applications. As a standard insulating transformer, it is rated for 0.25 kVA with 240x480V primary and 24/48V secondary voltages. It delivers a maximum secondary current of 10.40 A at 24V or 5.20 A at 48V and is suitable for 50/60 Hz operation. When field-connected as an autotransformer, it can correct a wide range of off-standard voltages, making it an economical solution for applications like commercial air conditioning, lighting systems, and induction motors.
