JM60060-1CR is a general-purpose thyristor power module, which is extensively used in industrial and mining automation equipment, process control systems, ship power supply systems, fixed-frequency home environment control systems, reactor adjusting circuit, heater circuit, etc.

The JM60060-1CR typically consists of two silicon controlled rectifier (SCR) or thyristor switches, a Phase Control Unit (PCU) and a high voltage rectifier bridge. The PCU is the heart of the power control circuit and is responsible for adjusting the thyristor opening voltage curve. It is typically implemented using a voltage regulator, opto-coupler, resistor and sensing transformer. The PCU senses the voltage of the thyristor and then controls the thyristor to trigger and release appropriately in order to regulate the current or voltage of the circuit for desired effect.

The rectifier bridge provides the high voltage required for the firing of the thyristors. It consists of six diodes and four switches integrated into a bridge configuration. The bridge rectifier is designed to handle high input voltages and provide AC or DC current outputs and also convert the voltage levels of variable frequency signals. Advanced bridges have built-in protections that can detect overload, voltage fluctuations, fault conditions, etc. and automatically shut off the power supply to prevent damage.

The main application fields of JM60060-1CR are motor control, AC/DC rectifier, welding inverter, power converter, frequency selected automatic voltage regulator, and loads switch. The working principle of JM60060-1CR is based on the control of the current and voltage of the circuit by regulating the opening and closing of the thyristors. The PCU is responsible for sensing the voltage of the thyristors and then controlling them to open and close as required. The rectifier bridge also plays an essential role in this process by converting the AC voltage to DC voltage, providing the necessary high voltage to fire the thyristors and transforming the voltage levels of the variable frequency signals.

The advanced built-in protections of the rectifier bridge ensure reliable operation of the JM60060-1CR power module in various application fields, such as motor control, AC/DC rectifier, welding inverter, power converter, etc., providing maximum safety and efficiency in the industrial and mining automation processes.
