xcluma 4000W 220V Ac Scr Voltage Regulator Dimmer Electric Motor Speed Controller

This is a SCR (Silicon Controlled Rectifier). It should be great for resistive type load.In my opinion, this is not good for inductive type load. SCR type voltage regulator are not mainly used to control the induction motor in a reliable manner. The main thing I wanted was to reduce the speed of my Kenstar room water-cooler further than what's provided by the lowest setting on the speed control knob. It uses a 1-phase 230V 50Hz 1.0A 107W 1/7HP motor. The main issue is whenever I reduce the voltage using this SCR regulator the motor does reduce it's speed accordingly and it's great but unfortunately it starts to heat up very high very soon. This is the reason I can't use it with my cooler because I think it will reduce the life of the motor.But I am keeping this great product nonetheless because it will be used for some other resistive type load. I am happy I have this one anyway.Thanks for this. Chinese hardware is great and very affordable with good quality. I wish India could be like that some day.

The item was found slightly deformed. But Working fine.Overall satisfactory.

very useful. Value for money

this is not good for inductive type load. induction motor not reducing it speed (RPM) The main thing I wanted was to reduce the speed of my coconut scraper motor to avivod injure to hand , it running full speed as it was , I tried it with a 100 w lamp also, it not dimming the light also , overall this item don't have any return policy on it but replace is there which i no need this kind of item anymore, overall straight away to scrap bin,

At the lowest range, it's output is roughly 90 volts. As you rotate the knob, it very quickly reaches 200V (within 1/3rd of its rotating range). So basically, I'm guessing most buyers will be using it at it's lowest range - see accompanying pictures.I've put this device inside a 4x modular gang box which I had to modify slightly to accommodate this. This way I can plug in any device that I need to slow down - typically my angle grinder and my drill machine.By the way, the connection terminals are Live-Neutral-Neutral-Live (the two on the left are input), and Earthing you connect to the screw on metal housing. I've given it 3-stars because I found it's ability to control voltage not very good - your choice is limited to low or very high.

Perfect solution for my project

Good

Quality of this voltage regulator is good. Just remember don't load up to 4000W otherwise it will burn. Also don't make a short circuit even for few milliseconds otherwise it will burn.
