Looking for a Bogart TM-48VA adapter for the Bogart tri-metric 2020

[Prosolar]

Guys....

the header says it all. I'm looking for a TM-48VA adapter for the Trimeteric 2020. This is needed so the meter will work with 36 and 48 V systems.

Google turned up nothing, and nothing on eBay either.

There is nothing on the Bogart website.

thanks,

mike
