Feature: 1. The governor features advanced technology, high efficiency, large torque and small heat generation. 2. The circuit board uses high grade double sided PCB. 3. High quality 50V1000uF large capacitor, with obvious capacitance advantage compared to other 100-220uF governor. 4. Power tube uses the IRF3205 high-power tube, never worry that the module cannot drive your motor. (Parameter drain current Id max: 82A; voltage Vds max: 75V; on-state resistance, Rds (on): 0.013 ohm). 5. The terminal adopts 8500 high current terminals, 300V 20A.
