Transformer fan speed controller RV 1.5 WT (weekly timer)

The transformer fan speed controller RV 1.5WT is designed to change the motor rotation speed by changing the voltage. The controller has a transformer's overheating protection function. The steps have fixed voltages and are switchable with a rotary switch. A single-speed controller can control multiple motors if the total of all motors' power consumption does not exceed the maximum current. The transformer controller has an integrated weekly timer. It is possible to set two motor speeds, which will be turned on/off using the installed weekly timer contacts.
