Keep-Alive for G Scale

(1/1)

Cal Trask:
What keep-alives are compatible with LM-3S-G modules?   Any brands recommended over others?

KPack:
This is a question that I don't have the answer to.  I'm very unfamiliar with G-scale or what sort of keep-alives are even available for large scale.  Whatever you use should be capable of handling the power that a LM-3SG can deliver.  The specs for the LM-3SG are available on the LM-3SG instruction sheet, available from Ring Engineering's website.

So you don't have to go find them, here they are (though I do recommend looking through it anyways)

Specifications
Maximum Power Input Voltage: 24 Volts
Maximum Motor Stall Current: 8 Amps
Maximum Output Current on a Single Output: 1.2 Amps.
Maximum Output Current on all Outputs Combined: 1.2 Amps.
Audio Output Power: 13 Watts into a 4 ohm load. 7.4 Watts into an 8 ohm load

Cal Trask:
I sent an email to RailPro Support asking if the item attached to the LM-3S-G was a keep-alive and got this response:

"It is a capacitor not necessarily a keep alive.  It does provide a small amount hold up time (in case of wheels not contacting track properly) but has other purposes too."

So I guess I will give it a shot without adding a separate keep-alive for now.
