If you're starting from scratch- go with the Coralux Storm X and take advantage of it's 12 bit dimming performance. The 10V Analog/ 5V PWM convertor was a stop gap measure, intended for use by people who had already purchased an APEX, but wanted to use it to control the new Meanwell LDD.

That chip looks like a winner to me. You could integrate that regulator and it's support components into an LDD-H PcB and maybe only add $5 cost to each LDD-H PcB.
I only added the SCW to my designs, to make them easier to build. I have no problem soldering little components myself, but others that use my PcB designs might find the added SMT soldering a bit difficult. The SCW provides the same "PlugNPlay" ease of use as the LDD-H or LDD-L.
Jeez I don't have enough posts to reply to a PM lol. Anyways I'll be working on my post count!

Ended up going with the Storm-X from Coralux. Ben was excellent to work with and even did some custom programming for me.
I am also in the market for some four-up boards if anyone has any.

Where at? If I can get em half the cost I may be more inclined to use them instead of going my way.
i was wondering if i could incorporate a 12VDC Coil DPDT Miniature PC Relay to control a circulation pump. i have seen the guys building ROV's using bilge pumps as thrusters.
it would be cool to do a tidal sim

what i really need is a 6up with a motor controller in place of one of the driver's. like in the link above or a better Design only needs 12v 2 amp ,
that would give me all i need for my build
4 ldd 700/1000 for display tank 1 ldd 300 for moon and 1 motor control reversible.
I've been looking at the stormX controller too, pretty cool
all i want to control is sunrise/set, moon phase, tidal sim ,temp controlled fan
tidal sim to just push water ramped up dwn not change lvl in tank,want to be clear about that.

The LDD actually needs significantly less than 5mA - the actual current draw was in the microamps range. The current draw was detailed in a post many pages ago :rolleye1: but suffice to say, the Mega will have no problems driving 25 LDD's.
Although, letoan will need to use something in addition to a Mega to be able to find 25 PWM control signals.
Digital I/O Pins 54 (of which 15 provide PWM output)
The problem would be: you will have to write application by yourself.
As far as I know there is no existing application to control so many devices.
Post #790, O2 measured it at on average 5mA maximum, the whole discussion starts several pages prior to that.
Letoan could use a couple of 16 channel servo control chips like the one used on the Storm X board. course those could be ran off of an Arduino Uno, unless you need the extra power of the Mega for the sketch and whatever else you'll be running with it.
