Isolation Transformers

Drive isolation transformers add an extra margin of

protection for AC and DC drives. They are sized to the

drive kVA requirements and are designed to withstand the

mechanical stress of current reversals and short circuits

associated with power semiconductor type AC and DC

drives.

• Three-coil, delta-wye conguration with fully rated

NEMA 1 enclosure

• ±5% fully rated taps on primary winding

• Ambient temperature: 104 °F (40 °C)

• Standards: ANSI C89.2, NEMA ST-20, UL506, UL1561

Features:

• Provide electrical isolation between the incoming line

and the drive electronics

• Convert input line voltage to standard drive input

voltages

• Minimize line disturbances caused by SCR power

converters

• Reduce power line harmonics caused by drives

• Protect the motor

controller by reducing

available short circuit

potential. This may be a UL

requirement in installations

with high levels of short

circuit potential
