This is a look at another Chinese industrial control component.

At first glance this phase angle power controller has a strong case resemblance to the common 12V chassis power supplies. But this is a beefy triac based mains power controller for things like lamps, heaters or some motors.
It has a few notable features:-
Nice case, beefy triac (one of the biggest of its type if it's original), extra circuitry to give greater stability and output symmetry at lower levels and a bit of effort to ensure that tracks are robust enough to handle fault conditions.
It does have two slight issues. A glass fuse instead of a ceramic one and a seemingly excessive resistor value in the snubber network. 4700 ohms as opposed tot he more common 100 or even 47 ohms.

CAN I CONTROL INPUT OF A 6KV TRANSFORMER WITH THIS CONTROLER? CAN U SUGGEST AN IDEA
I'm using this very thing to automatically limit a boiler power (from home assistant with esphome) so that it matches pv solar. I considered using a digital potentiometer but there were complications, mainly too much heat dissipation, and maybe live mains on the microcontroller so I ended up using a servo. After 1.5 years of continuous adjustment the pot gave up so I replaced the whole thing wih something very similar but this time detachable thus easily replaceable potentiometer. There are better sollution but this works for me. Needs active cooling.
Is that speed controller suitable for a wood lathe (universal 220V motor) for example? I would like to bypass the 4 speeds pulleys and belt system but my concern is that it could stall under load at slow speeds.
Im in a rabbit hole trying to turn the speed of my die grinder down. I used to be into electronics when i was young, this is very cool. I may try this one out.
Be careful with these boxes, the connectors appears to be swapped on different units, I'm still not entirely sure which way round mine is supposed to go. Although thinking about it, if it is AC, it doesn't matter which side the load goes on?

Hi do you think this regulator can be used to regulate the primary of a Micro wave transformer ?
Or it Can burn the MOT ?
Thanks 👍
Good Day. Any Chance of a Vid on a Simple DC Motor Speed Controller, with Specs and Circuit, SCR and Triac, for a light Motor Car or Vehicle? Much Appreciation. Wayne. Alberton. Johannesburg. South Africa.
hey bigclive! is there any way you can explain a typical ebike/escooter controller? i know the jist of it, but not being an electrical engineer there are parts that i cant understand, like for example, a 36v nominal controller, when i open it up i see capacitors for 63v, does that mean that its out putting 63v to the motor? and some times i see what looks like a little transformer? is that changing the dc supply to ac in the controller for the 3phase bldc motor? if you could do a video that explains how it works that would be very educational to alot of us that tinker in the ebike hobby, thanks for reading this!
could this control the speed of a swamp cooler motor
Just bought one today from Amazon…I need for my meat grinder machine to slow down the speed when I'm making sausage next month before Christmas 😏
Hi there can’t you make video how to use this product wired to a 3000w brushless motor with 3 phase wires and 5 pin hall sensor wire would like to know in Which of the wire is best to wired it from
This is why if I'm drawing out a circuit with a bridge rectifier, and it's not immediately obvious how it's being used, I do not draw it as just a "box" like you did. I draw out the full "diode diamond" instead, because that often makes it much easier to see what's going on if people are using a bridge rectifier in an unconventional way (i.e. not actually as a rectifier), which does happen surprisingly often I've found.
