FM4MMB117M5

FM4MMB117M5 is a double-side inverter thyristor module, designed for high-power low-frequency applications. It can be used in bridge, switched-mode, or inductive-load applications. The module consists of two full bridges, each of which consists of two SCRs in parallel. It also has an internal voltage clamping diode between the two bridges. This module is designed for use in applications such as induction heaters, induction furnaces, induction melting, and resistive load applications.

The working principle of the FM4MMB117M5 is similar to that of a conventional SCR module. The gates of the SCRs are connected in parallel, and the SCR gates are tied together. When an enable signal is applied to the gates of the SCRs, the SCRs turn on, allowing current to flow through the module. The enable signal opens the SCRs, allowing current to flow through the bridge. The output current of the inverter is controlled by the current flowing through the SCRs.

The main application field of the FM4MMB117M5 is the induction heating and melting process. It is used in the induction furnace to provide high-power, low-frequency current in order to heat and melt metals, alloys, and other materials. The module can also be used in switched-mode inverters to provide high output power and allow the device to control current with high accuracy.

The FM4MMB117M5 module is designed for operation in low-frequency applications in the range of 0.1 - 8 kHz. It can handle up to 4 kW of power at any given frequency. The module has an embedded temperature sensor to prevent the module from overheating, and it has current limiting and short-circuit protection. It also has the capability to adjust the phase of the current when it is applied to the load.

The FM4MMB117M5 is a reliable and efficient module for induction heating and melting applications. It is designed to provide high power and low-frequency output with excellent accuracy and performance. It is an ideal module for applications in the induction furnace, induction heaters, and switched-mode inverters.
