    The most versatile transformer available


ImperviTRAN was the first control transformer with integral secondary fusing, molded terminal barriers to protect against electrical creepage, encapsulation for maximum protection in industrial and hostile operating environments.

Micron's ImperviTRAN is their hallmark product, servicing the markets as the best industrial control circuit transformer available.

What does a transformer do?

A control transformer steps down the voltage in a power circuit in order to safely operate control devices (contactors, relays, pushbuttons, etc.). Typical control voltages are 120 or 24 volts AC. There are also times when other output voltages are necessary (instrumentation, flow meters, PLC's, etc.).

Marshall Wolf Automation can provide a transformer that fits the needs of the most demanding input or control
voltage application. Engineers are on staff to assist you!
