This is a very smart small digital Programmable Dimmer with Memory and Timer.

The items below are settable by the user

1 - Minimum output voltage 2 - Maximum output voltage 3 - Dimmer's number of steps 4 - starter

For example you have a lamp that you want to be able to dim. you want to be able to change the voltage from 40v to 80v in 50 steps. So you set the Minimum voltage to 40 and the Maximum voltage to 80 and the number of steps to 50. so the dimmer will split the 40 to 80 volts to 50 steps and the display will go from 0 to 50.

Imagine you want to change the motor speed with this dimmer and you want the voltage to change from 60 to 100v but at 60v , the motor doesn't have enough power to start but if you help the shaft, it'll continue working. so you can set the starter to for example 2 seconds. that means when ever you start the dimmer , it will provide full voltage to the motor for 2 seconds only and then goes to the set value. that helps the motor to start and then keep running with the defined value.

There is also 3 memory switches on the board. by holding each switch for 2 seconds, the current dimmer value will be stored in that memory so later you can use the preset values by pressing the memory switches.

There is also a 0 - 99 minutes sleep timer with increment of 5 that can shut the system off after the set time is elapsed.

The board can work with 50/60hz. The voltage needs to be defined by customer.
