regulator / rectifier MOSFET 700.18.53

Regulator / rectifier with MOSFET technology.

Spare part in original quality.

This new technology has revamped the concept of three-phase stair controllers. For many years these devices have been using Silicon Controlled Rectifiers (SCRs) to drive excess power from the generator to ground, keeping the battery voltage constant.

This was generally accepted and proved suitable for small to medium size generators in internal combustion engines. However, new MOSFET-based regulator technology is becoming more and more popular for its better performance and many other interesting advantages over SCR.

The demand for power in modern motorcycles and ATVs is increasing today thanks to the use of additional electronic modules, such as the injection system, high-efficiency lighting, numerous accessories, etc., more and more. This means a lot of power coming from the generator and the SCR bypass regulator will not be able to control it.

The main reason is low power efficiency, the internal losses of the controller lead to overheating and premature damage when currents greater than 35A are routed through the controller. As a result, SCR technology has reached a limit and is therefore not recommended for large vehicles with high energy consumption.

To solve this problem mentioned above, it was necessary to reduce the losses in the circuit. When the SCR is active (generator current to ground), there is a high forward voltage drop (approximately 1.5V @ 35A) as it functions as a power diode. When the current increases, the power loss (eg heat) increases in parallel.

DEVICE POWER (W) = TRIP CURRENT (A) X VOLTAGE LOSS (V)

Advantage:

- 3-PHASE SHUNT CONTROLLER WITH HIGH ENERGY EFFICIENCY

- OUTPUT POWER UP TO 50A

- PRECISE ELECTRONIC CONTROL OF BATTERY VOLTAGE PREVENTS USER FROM IGNITION

- LOW HEAT DEVELOPMENT LEADS TO SUPERIOR LIFE

- LOW POWER STANDBY MODE IF THE VEHICLE IS NOT USED

Unlike other transistors, MOSFET transistors can be designed as voltage-controlled switches, since an entirely different semiconductor architecture makes them more power efficient.

In use, they behave like a low-rated, high-current resistor that conducts all excess current from the generator to ground. As a result, the voltage drop is very low (less than +/- 0.2V @ 35A) and the power loss is drastically reduced. This has a direct effect on lower heating of the device and a long lifespan of the controller.

MOSFET technology has been continuously improved in recent years due to its wide application in consumer and industrial electronics. Semiconductor integration technology offers higher charging capacity in a small space with excellent efficiency. In addition, they allow for faster switching, greater reliability, and better control under heavy loads.

Rectifier diode performance is another important factor when it comes to power dissipation. Since all the output current flows through them, they must offer great robustness and stability, as well as efficient current control. Our MOSFET regulators use high current rectifier diodes with extremely low voltage drop, which help prevent overheating and meet the requirements mentioned above.

The internal DRIVER has been completely redesigned to meet the requirements of the MOSFET transistor. The battery voltage is constantly monitored so that the output current adapts to different consumption situations. The new electronic control eliminates the use of the ignition line, reduces the number of connections and simplifies the cable topology. It also has low power consumption in standby mode, resulting in very little battery drain when the vehicle is not in use.

This new technology allows the regulator's output power to be increased up to 50A while maintaining excellent voltage regulation. Additional benefits such as heat reduction, high efficiency and advanced electronic control make this new controller the first choice for monitoring your vehicle's battery cycle.
