The MM4310 provides a DC output, fully isolated from input, line power and ground, proportional to a DC input. It is useful in eliminating ground loops and common mode signals.

The MM4310 contains a superior input amplifier for narrow span inputs down to 10 mV.

All Wilkerson products are designed with RFI filters and lightning protection to reduce susceptibility to electrical noise and damage by lightning. It utilizes pulse width modulation to develop a pulse train with a duty cycle proportional to the input signal amplitude. This pulse train is coupled through a pulse trans former where the duty cycle data is converted to a proportional DC level in the output circuits.

TYPICAL APPLICATIONS
Eliminates ground loops and large common mode signals. Use for voltage / current scaling and conversion with isolation for buffering and noise reduction
