We are offering true online small ups system. technology : intelligent ups, using igbt technology latest design : microcomputer-chip based switching frequency : high frequency, (greater than 17.5 khz.) to ensure low switching lossesspurity of sine-wave ultra-fast transient responsevery low noise wide input range : 350 v - 475 v ac (three phase) or 160 v - 270 v ac (single phase)45 - 60 hz accurate output : 415 v ac 1.0% (three phase) or230 v ac + 1.0 % (single phase) 50 hz + 0.1 % (crystal controlled) ratings : 1.0 - 60.0 kva output power factor : 0.8 lagging to unity transient response : for 100 % step load change output stays within + 5% and recovers within 12 cycle metering : on-board programmable lcd panel meter to display following parameters :output voltageinput voltagebattery voltagebattery currentoutput frequencyinput frequencyvarious conditionsparameter of ups powerordigital meter showing inputoutput volts through selection. wave form : pure sine wave distortion : total harmonic distortion less than 2% for linear load total harmonic distortion less than 5% for non-linear load overload rating : 100 % continuous 150% for 30 seconds operating temperature : 0 to 50o c, 95% r.h. (maximum)our ups has passess environmental - tests from defence laboratory of r&de (engineers), dighi, pune. inverter efficiency : better than 90% transfer time : zero genset compatibility :ups system is fully compatible to any type of genset protections :output over-voltageoutput overload. The same shall be effective only for the normal continuous operations.output short circuitbattery under-voltageforced air-cooling to protect electronic other components from overheating. indications :mainscharger oninverter onsystem over-loadbattery under-voltageoutput underover voltage alarms : mains fail (musical alarm)battery low warning (musical alarm) low noise : less than or equal to 45 db (a) (standard) at 1.0mtr. bypass arrangement :in-built solid-state static switch provided (for ups of 7.5 kva and above ratings)manual changeover switch provided (for 1.0 to 6.0 kva ups systems). battery charger :charger is designed on boosttrickle (cccv) principle to keep batteries in top condition.uses high frequency design to ensure long battery life. useful options : servo-voltage stabiliser for use in bypass modesynchronisedasynchronised inverter configurationcritical non-critical redundant upsdual-redundant (hot standbyload sharing) ups configurationscott - connected transformer for single phasing of input ac mains and steppingdown the mains voltage from 415 v to 270 v ac in bypass mode (recommended for 10.0 kva ups and above with 3- phase input)computer interface (rs-232) for automatic unattended shutdown of file- server & monitoring of battery status. Options available for novell- lannt-windowssco-unixlinux.remote control indications & alarms panel to control the ups functions from a distance.
