5-level Step Transformer Sentera STR 1,5 A
Anyone who owns a duct fan knows how annoying the rewiring can be to change its' performance. Dimmers, however, often cause unwanted buzzing noise. Step transformers such as the Sentera step transformer regulate the speed of the motors without additional hum.
The Sentera STR 1.5 A regulates the speed of voltage-controllable motors by changing the output voltage. Grow fans, fans and pumps can therefore be manually controlled by means of a regulated output voltage at 5 different levels.
It is important to know the maximum supply current of the devices to be connected. Can only be used indoors.
This 5-stage transformer is ideal for controlling the performance of S & P Silent fans.
