3. Descriptions of MPWM100-10 Large power PWMA

MPWM100-10 is a switching mode PWMA,It can provide 1KW maximum load power for the load; the product needs two power supplies, +15V for the small signal control circuit power supply; 16V-100V motor power supply for the internal H bridge; input circuit control signal for the bipolar analog DC input(±10V) flat signal;Ouput pulse square wave signal frequency 0.9~2KHz.  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.
MPWM100-10 PWMA using excellent structural design to ensure the rated power conditions within the product dissipation power can be better passed to the shell without the need for external cooling device, easy to use and easy to install. The coonection of the product and system only needs to be done through the connection socket, without any external components.
