Power inverter technology design advantages


DA Series Inverter and UPS inverter laptop battery conversion of comparison:

Telecom used the so-called inverter biggest feature is one DC power supply voltage is 48V, but by the power supply voltage of 48V converted the UPS inverter actually does not apply to communications systems.

First: DA Series Hp laptop battery of inverter input noise smaller. UPS work with the battery pack are used alone, did not consider the parallel battery use, so the UPS, there is no taking into account the communication system by the most sophisticated anti-irrigation input noise, the input noise greatly. If the UPS battery pack with its shared communication system, it will interfere with and affect call quality.

Second: DA series inverter with a specially designed DC snubber circuit. UPS generally only communicate snubber circuit design, that is, when the boot to prevent COMMUNICATION impact UPS, but in terms of communications systems is not enough, and Compaq Presario 2100 battery (compaq 2100 battery) are dangerous. Communications room because of the latitude cpx pack used, their capacity is generally more than thousands of AH, when the DC switch instant, batteries have a very easy to damage the surge of UPS components, battery life is also easy to wear and tear, it must be in battery pack and inverter plus a buffer between the start circuit to address the issue.

Third: DA Series Inverter UPS capacity than double the increase of the inverter. When the general UPS’s load at startup, in order to prevent computer capacitive loading effect of the cold boot startup date that Hp 319411-001 battery moment (about 10ms period) will have a tremendous load current, so boot jumper to bypass municipal electric supply. However DA Series inverter is not, when the load restart or cold boot, all cold boot the impact of the burden by the inverter, so DA Series Inverter UPS capacity factor of the inverter are the reasons for double In this. DA series inverter with Hp F4812A battery polarity protection. Battery capacity of the engine room are very great, if modified by the UPS inverter when the battery accidentally reverse connected, the UPS will not only damage will be to do permanent damage to the battery. However DA Series battery polarity protection, when an error occurs will not be able to start, to avoid the aforementioned problems.

Some users think the UPS with 48V inverter, in the normal situation, the machine’s power supply by the electricity rather than batteries, so it seems to reduce the burden on the Hp F4809A battery. In fact, for the communications room of the latitude c610 pack used, their capacity for thousands of AH in general more than usual by the communication switching power supply (the capacity of several hundred amperes) on the battery pack to float. So there is no need to worry about DA Series inverter battery pack will increase the heavy burden. Moreover, because of the industrial power network interference, distortion, mutation greatly, for peacetime use of electric-powered city forms of UPS inverter, its load will interfere with the inevitable impact of the good work load. At the same time, because of rectifier harmonic currents generated, the grid will result in anti-irrigation pollution, because the city of a sudden disruption in electricity, Hp F4098A battery supply current from zero to the great mutation will cause an instant latitude c640 voltage drop, while the DA series of communications-specific inverter with its job completely unrelated to the city of electricity, the electric city of interference does not affect the computer load. DA Series inverter inverter damage only in the use of bypass system to the city electricity supply load. Therefore the use of inverter usual job of the city is also the electric isolation, purification.
