#1 VINCITORE

  • 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
