Please show the back side of the product in the image. So that we ( buyers ) can check power connector type / back cooling fan /and 110V,220V switch

Thanks for your suggestion. We will upload the rear panel image A.S.A.P. Please check the ‘Attachment’ & the following is F.Y.I. :- The Power Connector is a regular 3 Pin (Computer type) Connector. The Colling Fan sits inside the unit & only the Air Vents are cut into the rear panel. To avoid problems (& burn outs) due to mistakes (in our country) we have removed the 110/220V switch itself from the rear panel. However if you want, we can wire it out permanently for 110V & provide you. If you insist we can also provide a switch for this at additional cost.

What is the warranty of this power supply

1 year warranty against manufacturing defects. V A R TECH has a service center with engineers for after sales support throughout the life of the product.

Can I have data on voltage/ampere storage?

This is a regular power supply. Whatever you intend to do, you can do it using a Programmable Power Supply or any Power Supply with a PC Interface.

Does it support both 110V and 220V input voltages?

There is no 110/220V switch. But we will check Tomorrow physically if it is possible to wire it up for you & let you know.
