DBH-1A Motor Driver Board Module Dual-Channel  H Bridge PWM Speed Control Module With Heat Sinkfor Coreless Motor

<ul><li>Upgraded product comes with heat sink to improve the reliability and current detection circuit to realize a perfect PID closed- design</li><li>This board has a high speed switch. General coreless motors need 60kHz PWM frequency and this board is designed with a 200kHz switch</li><li>Suitable for all kinds of toy car motors, semi-conductor refrigeration control, DC motors, electromagnetic deflection coil control</li><li>This board can withstand high current overload and has brake function which can stop motor quickly</li></ul>

Brand

Specification: Description: This driver board is specially designed for coreless motor and will work great with coreless motors. It support forward &amp; reverse motor control and PWM speed control. This board uses MOSFET with extremely low internal resistance, with dead band control that minimizes the MOSFET switch losses and improves the utilization rate of power supply. MOSFET driver chip has built-in hardware brake function and energy feedback function. It is a choice for ordinary DC motor and coreless motor, etc. Features: Upgraded product comes with heat sink to improve the reliability and current detection circuit to realize a perfect PID closed- design. This board has a high speed switch. General coreless motors need 60kHz PWM frequency and this board is designed with a 200kHz switch. Suitable for all kinds of toy car motors, semi-conductor refrigeration control, DC motors, electromagnetic deflection coil control. This board can withstand high current overload and has brake function which can stop motor quickly. Single power source input voltage range of this board is 3 to 15V, if you use a power source less than 12V, this board is very useful. It can still work even the voltage of a 12V battery is as low as 3V. MOSFET is able to endure current shock with 0.003ohm resistance, which can quickly open the MOSFET channel and improve motor acceleration curvature, and also can quickly brake motor. It can make the car start up quickly and brake quickly. Specification: Model: DBH-12V Rated Voltage: 5-12 V/DC14.6V Maximum Quiescent Current: &lt;30mA±5mA Operation Current: 0A-30A per channel Maximum Internal Resistance per channel: 12m Ohm Impedance Load: 200kHz PWM Control Duty Cycle: 0%~98% Recommended Frequency: 1, Normal motor: 16 KHZ 2, Coreless motor: 80 KHZ 3, Semi-conductor Refrigeration: 500hz~80kHz Input Voltage : 1, Lower Voltage :0 to 5V 2, Higher Voltage :2.5-13 V board is compatible with typical 3.3 V, 5 V, 12 V Sampled Output Current: Sampled output power current for single chip micro controllers sampling to do current-limiting processing. CT Output VoltageV=CurrentA x 0.155 Size:7.2 x 5.7 x 2cm / 2.83 x 2.24 x 0.78" Package Includes: 1 x Motor Driver Module Note: 1. Input PWM duty cycle cannot be more than 98%, or the board won't work stably or even be damaged. 2. Select PWM frequency according to load type, please use recommended frequency. 3.Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
