Ensign Corporation announces flame retardant, compact, single and dual primary transformers for printed circuit board (PCB) mount, solder/quick connect terminals and lead wires. 

The Ener-G-Star transformers are designed for optimal efficiency and made of flame retardant materials (UL 94V0). Models are available with single (115, 120, 230 or 240V) or dual primaries (115/230 or 120/240V) input(s), and single, dual or center-tapped output(s). Output configurations are available in one volt increments (from 5V to 240V); therefore, providing you with unique output voltages and reducing the need for costly transformer customizations. Parts are UL, cUL, Class 2 approved, some VDE approved and all are RoHS compliant. Optional internal protection available upon request.

Typical applications include medical, isolation, thermostat and various types of controls.
