These frequency controllers can be used to be able to run a 380V Mill or lathe using a 230V mains connection. Further one has full control over the frequency so especially with lathes its great to be able to set the rpm with just a dial of the potentiometer, instead of having to change gears. We offer a range of controllers between 750Watts and 2,2KW
When using a VFD in combination with for example a lathe, if you wish to slow down the main spindel at a fast rate. Then this brake resistor is required. It turns the mechanical energy into heat. Also for safety we recommend it. Some motors can take 10-20 seconds to slow down. If anything happens, you are always too late then. With the brake resistor its decreased to about 1 second...
