Potentiometers

just wondering how I can up he resistance in a pot? I keep buying pots and everyone of them are between 90-96k I need at least 99 if not 100+.
Iv even gone and bought a Honeywell pot and that is only 96.9k. So can I ad a resister to up the rating whist still allowing it to dim to 0?

Thanks

For Dimmers that work on a 1 to 10 Volt signal:
Some of us added a 10k resistor in series with the dimmer pot. This allowed us to compensate for a pot which was greater than 90k but less than 100k. The 100k dimmer setting is what allows full power to the LEDs. The 10k series resistor will produce a 1volt dim signal when the dimmer pot is turned to minimum position.

The 3-in-1 dimming Meanwells dim wires will have 0.1 mA (one ten-thousandth of an Amp) current flowing thru them when a resistor (dim pot is connected to the blue and white wires).
Volts = Amps x Resistance
1 volt dimming signal comes form 0.1 mA (0.0001 Amps) flowing thru a 10k (10,000 Ohms)
10 volts = 0.1 mA x 100 Kohm.
And that's all I know about that.

Thanks, just saw the other post after I posted this, but is it any 10k resister?

Quarter watt (1/4w) would be fine. Not much power in those dim leads.

Thanks, so could be higher with no ill effect?

Higher wattage means bigger resistor. Why pay more for a fatter resistor when a skinny eighth watt resister would work just as well?

Correct, the wattage doesn't matter.

1/2 watt 10k for ELN-D/P models & 1/4 watt 10k for most other models.
