Setting up the 10x80W Dimmable T5 with EVG AP2F Card

[planetg]

Matthias/Mike

Below is a diagram of how I will be wiring my EVG card to the ATI Powermodul 10x80W T5

I understand that I can chain 2 ballasts to each of the ballast output, giving me a total of 4 ballasts on one card.

Question is can I link the control line to Ballast 1 as shown above but connecting the power supply of the Ballast 1 to a socket?

This way I will need to manage the zero voltage off separately but I will have the dimming controls. Am I right?

Btw, I'm using the Vossloh 2x80W Dimmable Ballasts.

Please advice

Firast comment is that you are overloading the EVG card! I think we already discussed this.

hi mike,

matthias was telling me that I could load 2 ballasts to each channel?

am i wrong or is he referring to loading 2 single tube ballast?

cheers

From the details you gave before the loading you were talking about exceeded what the EVG card is rated at.

hi mike,

you are referring to the relays on the main power right?
what happens if i don't use the EVG for switching on/off main but to control the 1-10V? will that be a possibility?

cheers

This is ok.
One channel of the EVG-AP can drive up to 2 ballasts.
Please refer to the datasheet of your ballast - the inrush current in sum must not exceed 100A per channel!

"Question is can I link the control line to Ballast 1 as shown above but connecting the power supply of the Ballast 1 to a socket?

yes - you are right
or just use a second EVG-AP

Matthias,

On the datasheet and the actual ballast itself, I do not see "in-rush current" specs.
However there's a current specs that says 0.74A. Are we able to deduce based on this?

Beginning to learn a lot from this! haha

Cheers

 

[Matthias Gross]

0.74A is the current during normal operation - not the IRC.
Some manufacturers don't mention the IRC. Maybe you must contact them for this information.
Osram has this information in the datasheet.
There is the IRC between appr. 35A (single 24W ballast) and 60A (double 80W ballast)

 

[planetg]

Matthias,

If the IRC is 60A for 2x80W, that means we cannot run 2 of such ballasts on 1 channel of EVG card.

Which means only 2 of such ballasts can be used per EVG card. Am I right?

Cheers

Matthias,

Does that mean I will need 3 EVG cards to support 5 double-80W ballasts?

Or alternatively wire the power to a socket but use 1 EVG to control the 1-10V?

Cheers
