Hi the Gang,



Two months ago I was searching connectors for a power supply from Emerson R48-3200 (48 volts 3200 watts) Someone from this group indicated me JONHON in china, it was exactly this manufacturer! Thank you for this nice input, I've ordered few of these connectors and powered up this power supply today. Now I need to find the operational manual and if it exists the service manual. At least the op manual to be able to configure this ps. I believe there is a digital bus to be able to configure the parameters and to ger the status and alarms. I've contacted Emerson but no answer from them. Could someone help me again?



Many thanks in advance. All the bests. pf

Google turns up several hits for Emerson products that incorporate the R48-3200 (p/n 1R483200) rectifier:

This catalogue has several references to the rectifier and compatible controllers (eg M500D, M501D, M800D):

FWIW, the "RELATED DOCUMENTATION" page in the following document lists several document numbers:

Hi Franc, & the Gang,

Thank you for your reply, yes I've all these I found on yahoo search, but no more. Someone from Emerson Network Power told me that these power supply products are managed by Emerson Systems Group, he gave me a generix email address but they aren't responding. Emerson Network Power told me they cannot help more, they don't have these informations.

Communication with SCU is by CAN bus.

In the good old days, you just plugged the damn thing in.

Hi RL,

Yes there is a SCU to control this ps, I would like to find the manual to build a home made SCU. I've just tested the ps connected to a dynamic load, I could run it at

45.7 Amps / 54 Volts during half an hour. My dynamic load is limited above 2kw, I couldn't test it up to 3.2kw... ;-( The ps is almost fresh, and in pulse mode at 2.4kw the output remain stable like a rock! Now my only problem is I cannot change the output voltage down to 48V and visualize the alarms.

It's a rectifier for 48V: default would be full current into the battery system, to allow charging to achieve a 'float' voltage of roughly 54V. It's strange, though, that this default doesn't time-out on a communications fault, or some other fail-safe. Perhaps that is unnecessary.

Most 48V system hardware will like 54V, this being within their normal operating compliance range. Some even allow operation to a 60V system float level (an economy of scale).
