LD-40PSU

Overview of Mitsubishi LD-40PSU

The Mitsubishi LD-40PSU is a manual power supply device designed for controlling the voltage of powder magnetic brakes and hysteresis brakes. It provides constant voltage output controlled via a dial on the panel, external signal voltage, or an external variable resistor, allowing precise adjustment of brake torque in industrial applications.
