 Posted: Thu Jul 04, 2013 1:47 pm Post subject: Low voltage indicator with dual alternators |
 |
|
I'm going to have a 60a primary and a 20a secondary alternator with B&C LR3C and LS1A voltage regulators respectively.
If in the event of a primary alternator failure, and I switch to the secondary, will the primary low voltage warning light (LR3C, pin 5) remain illuminated? Or will switching off that alternator open the low voltage circuit?

Wow! The TCW product seems perfect for the GRT issue. Was unaware of it. Thanks.
I'm not sure I have the ba...., I mean constitution to taxi about with the doors open. But I'm going to think about it.
I certainly leave them open in brisk winds and such. I've also cracked it and held on to it during taxi but I'd never have a passenger do that. But wide open 'eh?
At home, my field is rough and I'm having trouble imagining them bouncing around. On hard top... I can see it but...
Do you limit your door open ops in any way?

Our IBBS product line provides back-up power to devices like efis equipment as well as GPS and comm systems. One of the added benefits is that during engine cranking the auto transfer circuitry knows to keep the connected load from dropping out and resetting. Connecting our IBBS product to the GRT system is very straight forward and 1/2 the weight of adding another similar sized lead acid battery.
Also, if you don't need the full feature of back-up power and just want to resolve the issues with system resets during engine cranking, our IPS systems provide consistent, stable voltage to the connected load(s) with a maintenance free solution.
All the details are on our web site and can be seen at our booth at Oshkosh.
