Description

Stepless speed controller STL6 - 0.5 to 6.0 amps

This thyristor controller is an electronic speed controller for single-phase AC fans via phase control. The speed can be adjusted with the rotary potentiometer on the front. The ITR requires a mains voltage of 110 to 240 VAC, at 50-60 Hz. The maximum current is 6 A. There is also a choice of kick start or soft start and the minimum speed can be adjusted via an internal trimmer. The infinitely variable speed regulator has an on/off switch that allows you to leave it set at the set speed. The unit has protection class IP54 and is suitable for surface mounting.

How can I control AC fans?

With the stepless speed controller ITR-9 you can control the speed of single-phase AC fans. The speed is controlled by changing the motor voltage via phase angle control - Triac technology. The desired speed can be set with a rotary knob on the unit. You can, for example, connect several fans without any problems (as long as the total current remains within the Imax of the unit). The microprocessor also ensures that the phase angle is cut at the zero crossing of the supplied sinusoidal signal. This ensures a smooth and stable signal, even after switching the controller off and on. This significantly extends the life of the motor or fan.

Easy to configure

This electronic speed controller does not need to be configured. Once connected, the speed controller is immediately ready for use! If necessary, the minimum motor voltage can be adjusted via an internal trimmer. Kickstart or softstart acceleration can be selected via a jumper.

What does kick start mean?

With some motors it is recommended to run them regularly at full speed. For this purpose, you can select the kickstart mode with a jumper. The first 8 to 10 seconds after switching on the unit, the motor runs at full speed, then it runs at the set speed.

What does soft start mean?

In some cases, e.g. under heavy load, it is advisable to accelerate the motor slowly. To do this, you can select the soft start mode with a jumper. The motor runs for 8 to 10 seconds until it reaches the desired speed.

Minimum speed adjustable

An engine does not like to run too slowly. Then it heats up and possibly makes noise. It also shortens the life span. It is therefore advisable to set the minimum speed with the built-in trimmer.

What is meant by an unregulated output?

The unregulated output (230 VAC) is active when the motor is activated. It can be used to control an external operation indicator light, a damper, etc. For example, if the fan is deactivated, the damper is closed. When the fan is active, the flap is open.
