PWMDC voltage regulation,Adjustable duty cycle（0%-100%），Fully sealed finished product。

Take some time to see the instructions，Buy when it's right！

The chip output is in the form of negative on-off，Available forLEDDimming，It can also be used for DC motor speed regulation（Recently upgraded for motor speed regulation）。

PWMmodulation mode ，High power with constant current driveLEDNot applicable！

Function description:

1。MOSTube output type，Working for a long time, considering heat dissipation suggestions3Awithin（Real through current）；

2。Voltage range：DC3-14V（With anti reverse connection protection，The peak value of the output voltage is approximately equal to the input voltage）；

3。Shell size：49mm*28*20mm（Not including protective wire sleeves on both sides）；

4。PWMOscillation frequency approx10KHzabout；

5。Duty cycle（That is, the proportion of output high level in the whole cycle）by0%-100%Continuously adjustable；

6。Due to the upgrade, it is suitable for DC motor speed regulation，The positive and negative poles of the input terminal shall not be reversed；

Warning：Before power on, check whether the positive and negative wiring of the power supply is correct，Otherwise it will（Including but not limited to）Burn out the freewheeling diode at the power supply or output！！！
