High voltage low power regular UHU controller.
Hi,
I've just buldt three regular UHU controller and I use two of them for 24V motors and i want to use the third one for a 140V motor rated 1 A.
When i turn op the voltage to about 70V the snubber resistor on the output gives of quite a lot of smoke. With snubbere resistor i mean the 1k8 2W in series with a 100nf cap across the motor output terminals.
Can i remove this? what happens if i increas the resistor to 4k 4W?
I must say these controller are ingenious!! they are working great and it was actually quite easy to set the parameters. I was unable to get the system to oscillate so what i did was to use the go command and set the parameters so the overshoot became as small as possible. Is this the right way to do it?
best regards
chris
Re: High voltage low power regular UHU controller.
I used to improve the MG, TG, USG and MX series are high voltage resistors with axial leads. They are designed for high operating voltages (from units to tens of kilovolts) and are widely used as voltage dividers, absorbers in power plants, antenna equivalents, for spark extinguishing in high-voltage charging and discharge circuits, etc. Resistors of this type are resistant to significant short-term overloads ...
