NG Pro Power Server

Performance. This UPS performs slightly better than the TVS in the minimum output voltage to the load. This is 196 voltage as against 189 given by the TVS. Other performance parameters are good, although the maximum output voltage could be a bit lower below 245 V instead of the 249 that it shows. The switchover voltages cover a wide range, which means it doesn’t switchover to battery that easily. The backup time is the same as that of the TVS. Float voltage is also healthy. 

Features. This UPS loses some points to the TVS in features, where you have to shell out an extra Rs 2000 if you need the control software with it. Overall, it’s a very compact UPS for a 1 kVA model. Plus, it qualified at 95 percent of its rated load.
