RA & nano box driver

[d0lph1n]

Is it possible to control the nano box driver with RA?

I'm interested in buying their 13up board.

I can't seem to find any specification on their website.

The owner says it's not possible and recommends Inventronics drivers instead.

He says to use a 25w Inventronics.

I think all inventronics accept both Analog or PWM signals.
Just look in the datasheet of the driver and look for the dimming signal.

I found this one:
http://www.ledgroupbuy.com/inventronics ... ver-700ma/

Wattage: 25W
Max output voltage: 12-36v
Input voltage range: 90 - 305 VAC, 47 to 63 Hz
Input current: 0.48 A @ 110 VAC, 0.23 A @ 220 VAC
Inrush current: 60A at 230VAC 25ºC Cold Start
Dimmable: 0-10v
Dimming range: 10-100%
Spec: EUC-025SxxxDS
LEDs: 4-10 XP/XM CREE LEDs in series at 700mA

It says they use analog signals.
You can use them. You will also need the PWM-to-Analog lead wire.

I couldn't find a digital driver. The P version provides constant current:

I ordered my LEDs from Dave. I used EUC -025S070DS - EUC Series 25 W 0.7 A 36 V Dimmable Outdoor Constant Current LED Driver.

I ordered 2 x boards. One for refugium (board2) and one for the main tank (board1), both 12 inch cubes.
I'm planning to run the boards with the same pair of drivers , a pair of relays and RA for dimming:

Daytime
driver1 + relay1 (off): board1 - blue ch
driver2 + relay2 (off):: board1 - white ch

Dusk
driver1 + relay1 (off): board1 - blue ch
driver2 + relay2 (on): board2 - blue ch

Night
driver 1 + relay1 (on): board2 - white ch
driver 2 + relay2 (on): board2 - blue ch

Dawn
driver1 + relay1 (off): board1 - blue ch
driver2 + relay2 (on): board2 - blue ch

Each mode will have different dimming stages.

For runnign 2 boards, Dave suggested a 2 x 40w driver, one fore bleu ch. (board1+2) and one for white ch. (board1+2) but I'm not sure I need that much power since I'll never run both boards (white&blue ch) in the same time. What do you guys suggest?

I ordered 2 x 25w EUC -025S070DS from futurelightingsolutions.
I'll order the PWM-to-Analog lead wire from roberto.
