1. Features

Customer Design

Wide input voltage:16V~120V
Bipolar (±10V) Analog DC signal input
Max continuous input current 30A
The product includes a current limiting circuit
Work in the rated power without the need for external radiator

2. Applications of MPWM120-30 Large power PWMA

DC motor drive control
Drive the reactive load

3. Description of MPWM120-30 Large power PWMA

MPWM120-30 is a switching mode PWMA,It can provide 3.6KW maximum load power for the load; the product needs two power supplies, +15V is for the small signal control circuit power supply; 16V-120V 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.
MPWM120-30 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.
