Salicru Electronics 4KW heavy duty Online UPS with new cells 90d RTB warranty
Used heavy duty 4KW UPS We have tested these and installed new batteries (16x 12v 7AH type). It is fully working and ready for work on arrival. Let us know your requirements and we can quote.
You could extend the capacity of the battery pack by adding an external bank. The UPS is a pure sine wave, full time double conversion unit. It has low parasitic drain of around 200W when standing idle. It has industrial sized heatsinks and fans.
The transformer windings are a thing of beauty. It will also be resistant to inrush spikes because of the large EM bufferinging in the transformers. We have two units, the price is per unit.
The units are fully working but report a fault "no bypass present" as the bypass module is not installed. The UPS works perfectly providing power when on mains and also from battery when mains power is interrupted. We have performed long duration tests. We do not know the access code for the maintainance menus, so it is likely this error will always be reported, but the UPS does not beep, it just has the red alert light lit.
We have compensated for this in the price. The original documentation rates the runtime at 20 minutes, but we have used a different cell configuration (16x 7ah cells, rather than 32x 5ah cells) to save cost so this will be inaccurate. In our extended duration tests we ran for up to 48 minutes at full load with a larger than normal cell bank. This type of unit is from the old guard UPS design, where it is easy to spot/trace and fix problems due to board layout.
Design consideration was given to performance and longevity rather than power density (size). Under normal circumstances orders before 3PM are dispatched on the day of order. Large units / quantities may roll over to being dispatched the next day.
We try to meet all customer deadlines. All of our consignments are sent fully insured on a 24 hour service with our carriers. We cover all problems that occur in transit.
We have the packing materials to make sure that there are no problems in transit. Our warehouse is based in the UK.
