1kva online UPS is a kind of the most widely used in the current UPS market by series power transmission. Its circuit is complex, high cost, with high quality power output. When the normal electricity, city power enters into the rectifier is rectified to be smooth and stable DC power, a part into the inverter, through the inverter energy conversion to become pure, no pollution of alternating current for load; another part of the charger of battery charging. When the city power failure, 1 kva online UPS automatically start the battery power supply, the battery internal power energy through the inverter energy conversion, make it become pure, non polluting AC power to maintain the load. 1kva online UPS can effectively solve the power interruption, the upwelling of the power supply, voltage sag, sustained overvoltage, sustained undervoltage, frequency offset, power supply *, switching transient, harmonic distortion nine power problems, its performance characteristics are as follows:
1.Whether there is no market power, all the power of the load is provided by the inverter, to ensure the quality of the power output.
2.Output voltage stability, frequency stability is high.
3.City electrical interruption, the output voltage is not affected, no conversion time.
4.Since all the load power is assumed by the inverter, the output of the 1 kva online UPS is limited to the load, but the UPS equipped with the output isolation transformer is not limited by the application, such as the cable Reed series products.
5.Due to load power rectifier also assume 100% general 1kva online UPS, input power factor is low, no loss of power, input current harmonic faults in large power grid pollution, but Sored by PFC power factor correction circuit of the 1 kva online UPS can be city electricity utilization rate increased to 96% and nonlinear loads due to power loss is reduced to the minimum, so the PFC power factor correction circuit of UPS power supply more energy efficient, this is reserve and interactive 1kva online UPS is unable to compare.
