Can These Power Supplies Handle a 30/60V, 120A Load Continuously?

AI Thread Summary
The discussion centers on the suitability of two power supply models for a continuous load of 30/60V DC at 120A. The first model offers an output of 0-30V at 220A, which may be unreliable for the lower end of the required voltage range. The second model, with an output of 80V and a maximum current of 170A, exceeds the specified voltage for the panel switchgear. Concerns are raised about the compatibility of both models with a standard 415V three-phase supply without needing a voltage transformer. Overall, a power supply rated at 48V is recommended for better alignment with the load requirements.

Hi guys, I have few questions here regarding power supplies.
I have two models of power supplies and from the data sheet of the power supplies.
and I would like to enquiry on one of the model.
If i have to feed the load(Panel switchgear) fully 30/60V DC, 120Amp continuously for several hours.

The first model input has two selectable switching range,

range 1 (180-235Vac), 200, 208Vac (three phase)
range 2 (360-440Vac) 400, 416Vac (three phase)

second model has input rating of,

208Vac (three phase)

------------------------------------------------------------------------------------------
then the first model output rating is,

0-30V, 220A

and second model output rating is

80Vdc, 170A Max,

current during max voltage is 62.5A white
voltage during max current is 29.4V

---------------------------------------------------------------------------------------------

Can these power supplies fit the load fully (panel switch gear) of 30/60 V , 120 A for several hours, and could it be able to fit with standard 3 phase 415V supply from Main switch board without the need of any voltage transformer.

I am confused and sorry if the questions are silly.

Welcome tp PF.
Is the 30/60V = 30V to 60V, the range of acceptable voltage to the panel ?
The first supply 30V output is right on the lower side of the required voltage range. It may be unreliable.
The second supply output is 80V. That is higher than specified for the “(panel switch gear) of 30/60 V”.
You might do better looking for a supply with an output rated at the standard 48V.

Why are you even considering this second model, when your requirement is for 415V operation?
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
