## Description

ZOWZEA AC Motor Variable Speed Controller & Fan Speed Regulator - 15A 110V - desertcart.com

Review: Works with my high output fan - My fan has only ON and OFF. Putting this in-line makes it a variable speed fan, with very fine control. I'm very happy with this. When my fan is ON, the force is too much for most uses. Now, I can adjust it to what I need.
Review: GREAT! - GREAT!

## Features

- This variable speed motor controller is perfect for bench testing, experimentation, industrial applications, and DIY projects, offering precise control over fan speed and voltage regulation.
- The maximum power of this voltage regulator is 4000W,with AC 120-220V input and adjustable voltage output (0-220V), Rated current is 9A, can withstand a maximum current of 18A.
- This motor speed controller is equipped with a new bi-directional high power SCR inside.You can easily control the speed of your motor to your desired level using the rheostat.
- The output voltage of the product is a virtual voltage when there is no load. When a load (20W or more) is connected, the actual output voltage value is shown on the display.
- Note: Max power limit is 1500W for inductive loads (fans, routers, soldering irons, small motors) and 4000W for resistive loads (kettles, stoves, tungsten lamps ect).

## Questions & Answers

**Q: Can this regulator be used with both ac and dc power sources?**
A: It is for AC power

**Q: Is this item fuse protected?**
A: We have not installed a separate fuse on the product's circuit board. Still, the product's switch is equipped with overload protection, and it is stable and reliable when the controller is operating at a rated current of 9a or less.

**Q: What is the maximum power for inductive loads, such as fans and nail driller, that can be connected to this controller?**
A: The maximum power of inductive load is 1500W，and it supports these devices you asked about.

**Q: What is the maximum current that this controller can handle?**
A: The maximum withstand current of the controller is 18A, if you want it to work continuously and stably, it is recommended to keep the current at 9A and below when using it.

Cheap, for sure. And sorta kinda actually does control motor speed more or less. Voltage display is showing pretty random values. Right now, I have a motor running, maybe, at about 50% of output speed and the display is showing 162V (plugged into a standard 110v outlet). If I change the motor speed? Display will jump around between 20V and 190V. But, yeah, it sorta kinda mostly does actually work. 1 star if you were expecting a solid variac style speed controller. I give it 4 stars because I got exactly what I expected; a shoddily made, works by coincidence, motor speed controller whose voltage display might as well be a random number.
