    Converting 0-10 volts to PWM

    Has anyone used this circuit board for convertind Apex 0-10 volt control signals to pulse width modulation (PWM); e.g., for LED control?

    I'm curious also if anyone has used this board. I looked at it but ended up going with this instead as others have used it successfully.

    Interested in this as well. I'd like to control a Fluval Planted 2.0.

    Just ordered a Steve's LED Board to use between Apex and my Rapid LED's with Meanwell LDD drivers

    recklessop,
    Please keep us all posted on what you receive, how you mount and install it and how well it works for you.

    I have a prototype PCB coming back for converting APEX 0-10V to 3.3V PWM for controlling the Ocean Revive T247 light. I will post more about it after testing.

    The steve's LED board that I ordered has been in use for 7 months or so and is working great.

    I have the APEX programmed to fade in and out depending on the time of day as well as doing clouds and storms and all that stuff.... works well.

    One more option ... Try with this one: https://www.amazon.com/gp/product/B010LTA6J4
    I just bought it to control a DSunY Led Lamp (PWM, 4 channel, 20V).

    Are you just turning on and off with a plug timer or relay? I got wm fading but won't shut all the way off.... Also where did you find the codes for the clouds and storms?

    Everyone utilizing a PWM converter is doing so with Lighting control in mind. has anyone considered using PWM for computer cooling fan control? With limited space I am trying to using cooling fans over the sump as opposed to a noisy bulky chiller sitting in my family room and ideally would like to try to utilize the PWM speed control to limit the fans based on temp. has this ever been done before?

    I bought DSunY 3x LED Aquarium Light 360W Saltwater Lamp WIFI

    Will like to know how did you connect and program the apex controller to your DsunY Led Lamp?

    I updated the dead link in the first post in this thread with a valid one.
    I'm not a Neptune support rep. Please do not send me PMs with technical questions or requesting assistance - use the forums for Apex help. PM me ONLY if the matter is of a private or personal nature. Thanks.

    This is old I know but I just connected some DIY LED's using Steve's LED's pwm converter. I can power up the lights ok but I'm not sure I understand how to actually engage with dimming. The Varspd1 - 4 didn't seem to do anything and via the fusion portal I found the wizard which appears to put a percentage which I'm assuming is pwm power level, but my lights never dimmed. Trying to see maybe what I did wrong or how does one use a slider to adjust power levels, do any advanced control like sunrise, sunset, or changes by time.
