The MM4300 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.
                  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 transformer 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 large common voltage /  current  scaling and conversion with isolation for buffering and noise reduction.
