LED-Warrior10-01MOD

LED Dimmer - Instructions

LW10-01MOD is a dimmer controller for LED

applications. It generates a PWM signal to either control

a LED driver or to directly supply constant voltage LED

modules.

The LED brightness can be controlled by a potentiometer,

two buttons, or a single button. For button control a

power-on value may be set if the LED should always

switch on to a certain brightness level when power is

applied. A minimum brightness can also be programmed.

No mains/line power!

The LW10-01MOD is not designed to be connected to

mains/line power. The specified voltages have to be

observed.

Power supply

The LW10-01MOD can be used with 5.5 V to 40 V DC voltage. AC does not work. It is important that

the power supply does not require a minimum load for proper function, otherwise low dimming levels

and off mode can cause problems. The LW10-01MOD uses up to 25 mA for its own supply. Current

consumption goes down to about 6 mA when the LEDs are off.

Positive power supply is connect to "Vin", negative to "Gnd".

Compatible LEDs

LED strips, modules, lamps for use with a constant voltage can be directly driven by LW10-01MOD.

A maximum current of 4 A can be sinked by the module. The supply voltage must be compatible with

the LEDs.

Not compatible are LEDs that require a constant current for operation. To use those a constant current

driver with a PWM control input is required.

Connecting LEDs

The LED unit's anode end (positive) has to be connected to the suppy voltage, the cathode end

(negative) goes to the "Out" connector of the LW10-01MOD.

Dimming with potentiometer Potentiometer with 1 kΩ to 200kΩ may be used with LW10-01MOD. The two end terminals of the potentiometer are connected to "+5V" and "Gnd", the center tap to "Pot". Alternatively a potentiometer with 5 mm pin spacing can be soldered direct into the module. The brightness of the LED is set directly by the potentiometer position. Dimming with buttons The potentiometer function has to be disabled by connecting "Pot" and "Gnd" to allow button dimming.
