DROK DC Motor Controller
Product Parameters:
1. Power supply voltage: 9V-36V（please note that the power must not be reverse connected or more than 37V, or may burn the module, it is recommended that the power input in series 20A fuse.）
2. Drives without heat sink rated current 12A, rated current 12A ~ 15A needs simple cooling, 15A ~ 20A needs thick heat sink. (simple cooling - such as put a 1mm thick thermal insulation silicone pad under the module, and then 5mm copper column to the module fixed to the wall)
3. Control signal interface (orange) can provide 5V power supply, microcontroller no need additional power supply, the maximum supply current is 0.5A.
4. Control signal high level voltage: 2.0V ~ 5.5V, compatible with 3.3V and 5V TTL level;
  Control signal low level voltage: 0V ~ 0.8V, 0V when floating;Â
  Control signal voltage is 5V, the control signal current is 50uA.
5. PWM effective range: 0.1% ~ 100.0%;
  PWM signal frequency range: 0 ~ 100KHz (recommend 20KHz);
  PWM minimum effective pulse width: 200ns.
6. Operating temperature -25 ℃ -80 ℃.
7. Mounting hole diameter: 3mm
