Im dealing with a TELECT DUAL FEED 6/6 CIRCUIT BREAKER PANEL 23" PDU [https://telexpresslive.com/009-6212-2100-200a-dual-feed-6-6-circuit-breaker-panel-23-white/] which runs via 2AWG power cables to a large inhouse Valere Rectifier (Flatpacks). And then 10 AWG cables run power to the equipment in the cabinet. (routers) The Telect PDU is loaded with four 60 amp breakers PER SIDE. I can see the A and B feeds of this rectifier are consuming the following DC amps, which I determined by using a clip on multimeter with 400amp option on the 2AWG power cables that run from the Valere to the Telect. (4 cables total)
I checked this against 2 cabinets, which was necessary to make sure the DC amp metrics are consistent:
Cabinet 1 - (4 cables)
17.2 on black left, -17.9 on red left. -11.3 on red right, 15.0 on black right.
Cabinet 2- (4 cables)
17.0 black left, -16.5 on red left, -12.3 on red right, and 14.8 on black right.
We buy a lot of TDK LAMBDA HFE250048 power modules from Digikey, which fit into a 1U rectifier. We load these up in customer cabinets who don’t have a huge inhouse Valere rectifier like we do. The power modules by TDK Lambda hfe250048 are going into a 1U Rectifier Shelf. 1U is just to tell you that it only takes up one unit of rackmount realestate. The part number of this shelf im calling a 1U rectifier, though unimportant, is hfe2500s1u.
My question is… I gave metrics of DC AMPS above per CABINET. And I need the equivalent AC power required for the 1U rectifier we will be using for that cabinet to produce the DC feeds. Can someone help me with this translation?? I’m not going to have a Valere to work with eventually, and I need to hook these cabinets up to TDK Lambda rectifiers, not the Valere.
My reason for making this thread is 1) How many HFE250048 power modules [https://www.digikey.com/product-detail/en/tdk-lambda-americas-inc/HFE250048/285-2166-ND/2810343] do I need to meet the needs of my DC amp metrics above? 2) Whats the proper way to communicate total DC Amps of a cabinet? I don’t think left red left black right red right black is very practical…
Finally, if helpful, I will share a verbatim request given to me, which is the reason I started this thread.
Could you provide the power consumption of (1) cabinet of routers in the lab (Both the A and B feeds). There should be an ampmeter to measure the DC amps. Could you provide that information, as well as the equivalent AC power required for the 1U rectifier we will be using for that cabinet to produce the DC feeds?
