Robertshaw 620-402 Transformer 48VA 120-208-240V PRI/2.5-12-24V SEC

Robertshaw 620-402 Transformer operates as an efficient low-voltage control part that provides 48VA power while transforming 120, 208, or 240V primary voltage into 2.5, 12, or 24V secondary output voltages. The transformer operates in HVAC systems including furnaces and air handlers and thermostats to distribute safe control voltage to low-voltage equipment. The transformer maintains control stability for relays and ensures better system reliability and operational performance. This part provides multiple input taps along with adjustable secondary outputs which enable flexible system integration and better equipment defense mechanisms.
