Input voltage: DC 12V-40V, power: 0.01-400W, current: rated current 8A, large through current 10A, quiescent current 0.02A (standby state), frequency: 13khz, PWM pulse width speed regulation range: 10%-100%.
Equipped with 10A fuse, with power supply reverse connection, control voltage overvoltage protection function, equipped with high-quality potentiometer, suitable for DC motor speed control.
50V1000uF large capacitor, compared with other types of speed regulators, the capacitance value of 100-220uF has obvious advantages.
If you need the forward and reverse function, you can connect the positive and negative switch by yourself.
The power tube uses IRF3205, which is a big cow, and there is absolutely no need to worry about not being able to drive your motor. (Maximum value of parameter drain current Id: 82A; maximum voltage Vds: 75V; on-state resistance, Rds(on): 0.013ohm).

I moduli NGEN hanno una tecnologia di governatore del motore PWM altamente avanzata, ad alta efficienza che supporta grandi torque ranges while generating low amoreunt of heat.
La scheda del circuito utilizza un design di grado militare e componenti selezionati con stampa a bassa temperatura e caratteristiche di sicurezza come polarità inversa, protezione da sovraccarico e protezione da 10 A.
✅ Integrates a 50 V 1000 µF large capacitor. Compared con altri tipi di governatori che utilizzano mostly 100-220µF capacitance it has obvious vantages.
✅ Il tubo di alimentazione utilizza il MOSFET ad alta corrente IRF3205 che offre ottime caratteristiche di potenza (fino a 82 A di scarico, tensione VDS 75 V e resistenza allo stato 0,013 Ohm) per controllare qualsiasi motore DC.
I terminali della tavola utilizzano terminali ad alta corrente KF8500, adatti per 300 V20 A
