Question to all MEP 004A 005A owners in reference to the AVR 11

[peapvp]

Hi folks,

I am currently working on / repairing the 5th or 6th Exciter / AVR A11

Since these units are coming of age, a failure of A11 is preprogrammed.

Because of the low resistance of 2 to 4 Ohm of the exciter coil, these AVR’s cannot be easily replaced with low cost AVR’s which cannot be automatically excited.

I am about to design a replacement Exciter / AVR in the middle $ 300 to $ 400 range which will be a direct replacement with Amphenol receptacles like the current A11 and automatic excitation during start through S9 speed switch.

However, the original A11 was designed and as a consequence, became that elaborate, to allow paralleling.

My question to you, the owner is:

How important is the paralleling option?

The price target of $ 350.00 is based on a exciter / AVR without paralleling possibility.

Please comment and we are open to your suggestions
Thanks

Peter

Would not be any issue with this owner of a 005

Same here.... ZERO need or desire to ever parallel it. ( not that I have anything to parallel it with anyway... )

 

[Guyfang]

You know how I feel about it. Most people cant spell paralleling, let alone use it.

 

[Ray70]

I once tried Parallelling two Hydrollic cilinders into the same circit.... Damn what a speling dizaster I ended up with that day!
Gotta do what you can to keep sane these days and a little humor goes along way!

I am dyslexic. Every morning I get up and light a candle for my Spell Check.

Have a 004. Ill never parallel. Would love a spare drop in

 

[jamawieb]

I think it would be a great idea. I've never seen 1 person ask about paralleling the larger sets.

Methinks they parallel 'cause hauling a few little gensets is easier in a tactical situation than one big one to make the required kW.

That, and the loss or failure of one of several doesn't spell disaster.
