When the UPS load belt with more cases, in the absence of electricity when his duration will be short
But if a UPS in the case of electricity, there will be no load too much, and over load, can not work properly?
Each device has a rated power, if played this power, will certainly damage the equipment, UPS is the same.
The proposed load is less than 80% of the UPS capacity, because some load will have a high starting current, the load is too large will lead to UPS downtime risk, after the UPS problem can directly consult the Shanghai Wu Mai Electronic Technology
Under normal circumstances, we are equipped with UPS power supply, first of all, if the load power, select the UPS must be greater than the load power 20% -30%, if it is emotional load, it needs more, if the overload operation, UPS will be protected.
If the UPS power supply capacity is nKVA, the output power factor is cosφ (conventional 0.7 or 0.8, depending on the load)
1. Then the UPS full load load is: n * 1000 * cosφ (W)
2. General UPS with 30% -70% of the load is reasonable, then the actual load with n * 1000 * cosφ * 0.7 (W) more appropriate.
3.UPS power load is too large will alarm, the use of the instructions will generally have a detailed description of different types of different brands of UPS overload capacity is not the same. Backup or online interactive UPS load is too large will alarm, and in the specified time automatically shut down the UPS output; online UPS load is too large will alarm, and in the specified time jump bypass, by the electricity directly for the Load power supply (if the load is short-circuit directly off the output, do not jump bypass).
