## Description

1803BK 1803B Low Voltage DC Motor Speed Controller 🌠 PWM DC motor speed controller, with switch function, with start-up LED light. 🌠 Input voltage: DC 2.2V-15V; output voltage: 1.8V-15V. 🌠 Maximum continuous output current: 2A. 🌠 Maximum output power: 30W. 🌠 Do not directly connect the DC power supply of the DC motor speed controller to household 220V AC power. 🌠 The product has its own 2A self-recovery fuse, which will automatically disconnect when the current is too high, and will automatically recover after the fuse cools down. 🌠 Please use an appropriately rated fuse (rated slightly higher than your expected maximum current) to ensure safe operation. packing list 2 X 1803BK 1803B Low Voltage DC Motor Speed Controller

Review: Inexpensive power regulator that works - Prior experiences with Bojack products have been excellent and this is no exception. It is not a potentiometer but an easy to use power regulator that works very well with a Practical design for hobbyists.

## Questions & Answers

**Q: Does this draw any power when switched off?**
A: I guess it will draw few mA for 555 timer.

**Q: does this controller work in forward/reverse mode?**
A: no, not specifically.  For most types of DC motors, you could use an appropriately rated switch (DPDT rated for more than the amperage of the motor) to reverse polarity, and thus direction easily enough...

**Q: will this work on a car heater fan?**
A: No. It is not meant for that.

**Q: will this work as a dimmer for LEDs?**
A: If your leds are 12V DC led strip up to 5 amps,  then yes you can use it as a dimmer. In fact, there is a LED on the board for indication and its brightness shows the PWM duty cycle.

### ⭐⭐⭐⭐⭐ Inexpensive power regulator that works
*by A***N on December 16, 2025*

Prior experiences with Bojack products have been excellent and this is no exception. It is not a potentiometer but an easy to use power regulator that works very well with a Practical design for hobbyists.

### ⭐⭐⭐⭐⭐ Works finr
*by D***L on January 5, 2026*

Works just fine

### ⭐⭐⭐⭐⭐ It wasn't the same size as the one I was replacing but it does control the fan speed.
*by J***G on November 7, 2025*

I burned out the factory one in a 12 v fan. This resurrected the fan but did not fit in the old cigarette lighter plug so I had to McGyver a small box to enclose it. The fan works again though.
