Hi all. Anyone have a CP100 MUC\6 unit gang charger? I'm looking for the output voltage and current rating on the plug in power supply\wall wart. I had a customer return some rentals the other day sans power supply. Parts ID won't or can't tell me what the part number is. Apparently a top government secret. As of now, customer will have to replace the entire charger at nearly $300.00 I'm sure I can find a generic replacement power supply for $20.00 but I need to know what voltage and current rating first.

Let me know if you can help out. Model # for WHOLE charger is NNTN4028BR.

Mucho Apreciatto.
