The voltage regulator specifications as following:
input AC：220v/380v - 120A ，

OUTPUT DC： 0-220v/380v.

then I just thinking to use the piggyback engine management analog signal output 0-5v to control the retarder load level. 

is it possible?

@toni is it working with the retarder brake?

Thanks !

I think i skip this product and try this... https://www.aliexpress.com/store/product/300A-closed-loop-voltage-negative-feedback-single-phase-AC-solid-state-voltage-regulator-module-220V-380V/1162433_32606038407.html?spm=2114.10010108.1000023.19.3aee3e7fhB3OmG

Its closed loop and negative feedback.

I read that somebody had already done this but some reason had not worked.
Can anybody see any reason why it not work?

Toni

My brake is reworked to 96v 40amp 

probably that was another thing why doesnt work corectly 

There was a guy that tested the open loop version with little success. 

The closed loop version may work better, but I don't know if it is fast enough. 

Toni,

I am sceptical, but it is always interesting to look at options.

It needs a 0-5V or PWM or similar control input, does it have one? Also, with some SCR controllers we see that they are not made for the speed we need. You want almost instantaneous response when you change the input when controlling eddy brakes. For most applications this is not necessary (heaters, light, even motors), so they are slow. It also needs to be able to drive an inductive load (like a motor), otherwise it will need additional components. It says in the text that it can drive "small motors", yet it is rated for 10,000W which for me would mean a BIG motor. So who knows what that means. 

But it is so cheap, please let use know the results if you test it. 

I think problema come with amperage. check the specs you need with that Eddy brake.

Sportdevice sell power supply ready to wire and run.

What are pins 1, 2 and 3 on the Semikron SKPC200-240 phase angle power control module used for  ?

I didn't  mean restrict it to a specific model , the Semikron SKPC200 was just used as an example. 

All l know is pins 5 and 6 on the Semikron SKPC200 module must be some form of high speed opto_couple as far as the rest of the components triac's , , SCR's , diodes , resistors and capacitors l have no idea.

Josp on you website you have drawn a symbol wiring diagram and shown how to connect yourdyno V3 and V4 you left out the snubber circuit out the picture ? Any reason why but yet further down that page you mention using a snubber filter with a different power control model ?

It is definitely doable. It is standard technology. But I would not go that way for only 1, then I would rather use components like Semikron or even SportDevices, which is plug and play. 

SportDevices by the way has a more powerful unit, slappynuts, you can contact them.

How hard would it be to build a  purpose built Semikron SKPC200 circuit board ? 

I got report from a guy that tested it and he could not make it work. He ordered the unit without feedback. Maybe the unit with feedback works. Anyone else has tested? 

Anyone test this yet? I am getting ready to pull the trigger on power supply for my 96v Telma. It looks like the sport device will limit my TQ to about 75% because of the amperage required. 

Hi,

I have ordered one of those for testing! BUT: Read the spec carefully, you need to multiply the max current by a factor 5 for inductive loads (like eddy brakes). I ordered the 150A version, price difference is not that big. 

It looks quite promising from the spec. You just need a diode bridge in addition, which would bring the total cost very low.
