Transformer speed controller HRB HAVACO
HRB HAVACO transformer speed controllers are designed to change the speed of motors by changing the voltage. The regulators have a function to protect the transformer from overheating.
All regulators have a 230 VAC output for connecting actuators, heaters, relays, integrating the operation of accessories with the operation of the fan. More than one fan can be connected to one regulator, provided that the total current of all motors does not exceed the regulator's limit value.
