Transformer speed controllers RT ..EX
Transformer speed controllers RT ..EX are designed to change motor rotation speed by changing the voltage. All controllers have an overheating protection function. The steps are fixed voltages and switchable with a rotary switch. A single speed controller can control multiple motors if the total of all motor power consumption does not exceed the maximum controller current.
