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

In summary, the conversation discusses two models of power supplies and their input and output ratings. The first model has two selectable switching ranges and an output rating of 0-30V, 220A, while the second model has an input rating of 208Vac and an output rating of 80Vdc, 170A maximum. The question is whether these power supplies are suitable for a load of 30/60V, 120A for several hours and if they can be used with a standard 3 phase 415V supply without a voltage transformer. The expert suggests that the first model may be unreliable due to its output being on the lower end of the required voltage range, while the second model's output is too high for

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?
 

1. What is a three phase power supply?

A three phase power supply is a type of electrical power system that uses three alternating current (AC) voltage sources that are out of phase with one another. This allows for a more efficient and balanced distribution of power compared to a single phase power supply.

2. How does a three phase power supply work?

A three phase power supply works by using three separate conductors, each with its own alternating current (AC) voltage source. These sources are out of phase with one another, meaning they do not peak and valley at the same time. This creates a more stable and efficient flow of power.

3. What are the advantages of using a three phase power supply?

One advantage of using a three phase power supply is that it allows for a more balanced distribution of power. This leads to a more stable and efficient flow of electricity, which can be beneficial for industrial and commercial applications. It also allows for higher power transmission with lower voltage, reducing the need for thicker and more expensive wiring.

4. What are the common applications of three phase power supplies?

Three phase power supplies are commonly used in industrial and commercial settings, such as manufacturing facilities, data centers, and large office buildings. They are also used in large appliances and equipment, such as air conditioners and refrigerators.

5. Are there any safety concerns with three phase power supplies?

Like any electrical system, there are potential safety concerns with three phase power supplies. It is important to follow proper safety protocols and use caution when working with or around these systems. It is also recommended to have a professional electrician install and maintain a three phase power supply.
