The Huawei R4850G2 is a very capable 48V Telecommunications grade power supply available brand-new at cheap surplus prices (normally under $100 USD). Rated at 3000W, it can deliver a considerable 56.1A when powered from a suitable 200-240V rated AC source. .
I was first made aware of the R4850G2 by YouTuber Schematix. He presented a 17 minute video on the power supply at Cheap 3Kw PSU for. .
The power supply is designed to be inserted into a slot/backplane and hence all connections to the power supply is by means of a edge connector. Inclusion of Pre-charge pins allow multiple units to be paralleled and hot swapped. Huawei go someway in. .
The CAN interface operates at 125kbps with extended 29 bit identifiers. On power up, the unit will send out unsolicited packets and this can. .
As indicated earlier, I had also purchased a mating connector for the PSU from ebay. Below are the pictures on arrival. On the bottom of the connector is the part number. It appears to. [pdf]
