How to select the UPS power supply
Multi machine power supplies are available for each other, and N is available in M (N, M for digital). The problem of parallel use of UPS will be involved in multi machine power supply. Because the UPS parallel power supply phase of each machine must agree on this point, the strategy is different, is common to a table clock or electric is synchronized, but when the "command" fault, transfer technology, operation command (set), great the differences between different products; another is a "foreign" recognition of UPS (electric or other UPS) phase function, but has a greater impact on the system reliability sampling scheme.
If a single power supply capacity, can choose the corresponding battery and host. Single power supply can be divided into hot standby power supply and online power supply. The former uses city power normally, and UPS is used in power failure; the latter uses UPS directly, and when UPS fails, it uses city power. The single power supply can also be divided into single and double batteries, the former will decrease the standby power supply during the battery maintenance, the latter will fall by half at most, and the battery maintenance can be divided into automatic and manual maintenance.
Only when the power supply scheme is determined can the UPS be selected, otherwise there is no way to start.UPS (Uninterruptible Power System/Uninterruptible Power Supply), namely, uninterruptible power supply, the battery is connected with the host, the host inverter module circuit of the direct current into power system equipment.UPS power supply, there can be a variety of power supply forms, type selection should be based on the need to select the corresponding model (type).First, the power supply capacity must be determined, i.e., how much power is available for the power plant?.
The various functions mentioned above can require UPS to have the corresponding "intelligence", and a considerable part can be achieved by the after-sale service of the manufacturer or by manual means. Only a comprehensive assessment of the use requirements can be used to determine the UPS model to be selected.
