A stack of these just arrived, cheap.
TDK-Lambda PFE1000F-48/T AC to DC PSU
Output 48Vdc (38.4 - 57.6V) 21A so a kW each
Very flexible world-compatible input, 85-265Vac 47 - 63Hz
About 6" x 4" x 1/2" thick, all sealed up, and conduction cooling, so silent, no fan!
So far I'm thinking I scored gold. . .
But total noob here on the AC side, please help me be safe with this stuff.
Especially since no Earth Ground available when mobile.
Obviously at the low end (Japan / US household circuits) will not put out full power, so planning to parallel to get about 3kW in total, each unit can be powered by a separate circuit or generator.
Just can't find the paralleling appnote referenced from the data sheet 8-( Other models just say make sure no connections to ground, and get Volts output tweaked the same at 70% of load. Obviously will ensure the chassis / heat sink isn't exposed, but apparently the case is isolated from the internal circuitry - to be verified.
Anyone know a good way to non-destructively attach wires to those little posts?
Also any ideas on what the circled abbreviations mean?
