I am looking to reduce the current cost of our Electrical LV Panel and one thing that is adding excess cost is Power supply unit. We have 4 units whose details are mentioned below. Location - India; All are single phase 50Hz units.

Device ID |
Requirement |
Device Description |
Total Load |
| PS1 | Powering UPS | Power Supply 100 VAC -240VAC I/P, 24VDC 20A O/P | 15A |
| PS3 | Powering 24VDC Components like Microcontrollers, Sensors | this is a UPS with battery backup option. 2 numbers of 12V VRLA batteries are Placed in series. Input voltage to ups is 24VDC I/P from PS1., 24VDC O/P, 20A 480W. | 15A |
| PS4 | Powering 24VDC LED and ADC component of Microcontroller | 24VDC-DC Converter 14.6A O/P. The Input is given from the above PS3 UPS for this | 10A |
| PS2 | Powering 24VDC Fans | Switching Power Supply 350.4W 24V 14.6A Redundant Function. | 10A |
Total Max Load from UPS is 30A.
The idea here is to convert All these requirement needs to be into a single UPS with Battery backup option, 230VAC Input to 24VDC Fixed O/P, 40A, UPS with Battery backup option
The Battery Back-up needs to 65AH 12vdc, 2 Batteries in series.
Now the Question here
1) What are the Pros and cons of using this setup from a technical Point of view
i have mentioned some of it below
|
Advantages |
Disadvantages |
| 1) Cost Reduction when explored with alternate manufacturers 2) Reduction in Device Dimension and hence Space Reduction inside the Panel | 1) Individual maintenance and diagnostics of each part of the UPS cannot be done. Any Problem with the UPS will result in complete power shutdown and Business interruption 3) Part replacement will be expensive 4) Separate Fan Power control is not Possible |
2) Has anyone come across the above type of UPS, if so need little details about it.
3) Any links on Mechanical and technical aspects will be appreciated.
PS: i have googled and sent some queries to UPS manufacturers.
