3.Descriptions of MPWM100-50 Large power PWMA

MPWM100-50 is a switching mode PWMA,It can provide 5KW maximum load power for the load; the product needs two power supplies, +15V is for the small signal control circuit power supply; 16V-100V is the motor power supply for the internal H bridge; input circuit control signal is the bipolar analog DC input(±10V) signal; Output pulse square wave signal frequency is 2KHz.  When the output current is greater than 50A, the circuit will close the four power driving tubes of the H bridge circuit to make the product into the protection state. The circuit can back to work normally again until restart-up.
MPWM100-50 PWMA has excellent structural design to ensure  the product’s dissipation power can be better passed to the shell without the need for external cooling device under the rated power conditions.  Easy to use and easy to install. The connection between the product and system is through the connection socket only without any external components.
