Delta Amplon RT 6kVA UPS Review

Delta Amplon RT 6kVA UPS is the right solution for power failures and disturbances. The company uses double conversion on-line technology to deliver the high performance and protect IT systems, network equipment, Voice over Internet Protocol (VoIP), telecommunications, and light industrial applications.

Build and Features: It comes in a tower or rack configuration with an LCD display. The metal body is solid, built to offer complete protection from damages. With an optimized 2U form factor in a solid enclosure, it can be installed in a standard 19-inch rack space easily.

The LCD screen displays the UPS capacity and battery status by simply using the buttons placed beneath. Press the ‘On’ button to activate the display and then press ‘Up’ and ‘Down’ buttons to move forward or backward. You get to know about the UPS total back up time (shows “Remaining time” in minutes that depends on the load it has and batteries’ charging status), batteries capacity in voltage(V) and percentage(%). The display also shows input, output, bypass voltage in V and Hz as well as the standalone load on the UPS in kilovolt-ampere (kVA) and percentage.

Amplon RT UPS comes with 16 batteries of 18 AH, each battery has 6 cells, which are fixed in a parallel connection. It employs the double-conversion on-line technology which ensures better filtering and more stable voltage to the load.

Delta UPS comes with InfraSuite PDU (Power Distribution Unit) to offer optimal power management, which provides complete power protection and distribute the power to equipment. This can be added to single of three phase input voltage.

Performance: Delta Amplon RT is a genuine parallel-redundant UPS that offers worry-free protection to your systems. It’s capable of delivering high power density and input power factor, and low current harmonics. With an output power factor of 0.9, the Amplon RT UPS was able to handle the load of more than 100% (6kVA or 5400 watts) of its capacity. We connected 12 PCs and four servers, which loaded the UPS to 80% of its rated capacity. The UPS handled it pretty well and was easily able to provide battery backup for 7 minutes and 18 seconds. In fact, the UPS even held steady when we connected a load that was 124% of its rated capacity.

The UPS is well-designed and keeps the float voltage to 2.26 Volts per cell, which is well-within the limits. The UPS has a fairly wide operating voltage range and doesn’t switch to battery so long as the voltage remains between 155 to 306 Volts. It’s output voltage also remains rock-steady at 231 volts irrespective of the input voltage.

The UPS falls into economical range as it costs Rs 14.25 per VA. Additionally, you can add charger board to reduce the recharging time as well as include external batteries to extend the backup time. The system supports up to 200 AH battery, in which till 42 AH, it can handle the load alone, but beyond this you need include additional charging board.
