48 VDC 12.5A 600W Regulated Power Supply
can a power distribution block be used to run multiple components off of one power supply?

Does anybody have any idea as to why the unit would power up, led and fan comes on, then units led dims down and also no output voltage, yet the fan stays running? This has happened on 2 units in a row.

Would there be any way to use a 12v trigger with this power supply?
Unfortunately you would need to build a full relayed circuit with this power supply in order to use a triggered input.

Possible to do remote turn on/off
Is it possible to hook up a remote turn on/off to this power supply? If so, how?
Unfortunately this does not have any kind of trigger or remote turn on feature like an automotive amplifier. The only way would be an in line switch on the power cord.

Can you hook up (2) of those in parallel?
I'm looking to build 2x250W IRS2092 based Class-D amplifier (p.n. 320-313# and trying to achieve the lowest distortion possible at 4 Ohm using B-G RD50 Planar Transducer. I would like the power supply to cover the worst case peak current of 16A #8A per channel; 250W/ch; Re=4Ohm# and still have some headroom left over.Is it possible to connect #2# of those power supplies in parallel to double the current capacity? I that case I'll need #4) power supplies total. I'll be isolating the metal cases from one another.Thanks,Will
You may well be able to parallel two of these supplies but you'll have to use some isolation diodes between them to keep the two supplies from looking like loads to each other. Here's what I mean. Some types of switching power supplies are sensitive to what they see on their output as they "start up". Also, some supplies start up a little faster than others. At times, the slower supply might interpret the voltage that just showed up on its output terminals (from the faster supply) as an overload condition, causing the supply's internal protection to shut the supply down. Thus, it never starts. Adding the isolation diodes (I use a big full wave bridge mounted on a heatsink) allows both supplies to start normally. Well, it should, anyway. With this kind of voltage and current available, proceed cautiously. You don't want to smoke anything. You may also want to add a load resistor across the output to draw 50 milliAmps or so. This lets the output of the supply "see" a ground reference and helps with stability. I don't guarantee this will work with this particular supply, but I've used it successfully in the past, so it's worth a try.

Can you put a step-down transformer on the output?....
...To lower the voltage to a usable level with the sure 6x100w Class-D Amplifier board, or would the added Inductance mess with the clean output?and yes I know there'd be power loss. Ohm law.... really important ;)
Unfortunately this is not possible because this is a switching power supply.
