The MM4380A provides a DC output proportional to a DC input. The output is fully isolated from input, line power and ground. The unit is useful in eliminating ground loops and common mode signals.

Input and output ranges are user settable. Each may be voltage or current, with or without offset. The output response may be normal or reverse-acting. A fully labeled set of jumpers selects the input and output ranges. The MM4380A is identical in size and fully interchangeable with fixed-range modules such as the MM4300 and MM4300A.

All Wilkerson products are designed with RFI filters and lightning protection to reduce susceptibility to electrical noise and damage by lightning. It utilizes a feedback VCO to develop a pulse train with a duty cycle proportional to the input signal amplitude. This pulse train is coupled through a pulse transformer to the output circuitry, where the duty cycle data is converted to a proportional DC output level.

TYPICAL APPLICATIONS

Eliminates ground loops and common mode signals. Use for voltage/current scaling and  conversion with isolation for buffering and noise reduction. Single unit replacement module provides field rangeability for all normal input and output ranges.
