LVDs are mixed blessings. Many folks don’t use them any more. Especially if you have a back up generator. If the LVD trips, then it generally requires a truck roll when the power comes back on because things in a larger NOC do not always gracefully recover from having their power interrupted without warning.

Some folks feed both the rectifier and batts through a circuit breaker. If you do that you need to make sure the breaker can handle the max output of the rectifer or more. When there has been an extended power outage the batts will max out the rectifier current. From: Scott Vander Dussen Sent: Friday, March 4, 2016 1:26 PM To: [email protected] Subject: [AFMUG] Eltek Rectifier Huh? Trying to figure these things out! I purchased and built an Eltek rectifier product using these products: CG1S-AUN-VC COMPACT POWER SHELF / REAR WIRE 200AMP MAX 48V UNIVERSAL OUTPUT POLARITY BC2000-A01-10VC 48V, SYSTEM CONTROLLER W/ ETHERNET, NEXTGENERATION, W/ CLEI V0750A-VC RECTIFIER, 840W, 53.5V, 15A, FAN COOLED (BOTTOM TO TOP) -INPUT: 90-264VAC It seems like this just takes AC power and gives me 48v DC out. I was expecting it would also attach to a battery array and provide charging of those batteries plus use their power source if grid power was lost. Am I totally wrong on that? I don’t see any method of connecting batteries to this power shelf :/ Noob out, Scott
