Songyuan City APCUPS uninterruptible power supply (brand guarantees) APCUPSSURT6000XLICH APCUPSSURT6000XLICHUPS power use must have a strict scientific procedures: (1) UPS power supply places should be placed away from direct sunlight, and leave adequate ventilation space, while, prohibit the UPS output port connected with the inductive load. (2) When using UPS power supply, should be sure to follow the manufacturer's product specifications relevant provisions to ensure that the connection is live, neutral and ground to meet the requirements, users can not change their mutual order. For example, the United States Hills licensing UPS AC input power supply wiring and connection of the AC input socket opposite. APC also need attention such as phase sequence, otherwise the phase sequence error alarm occurs, other brands as well. 3) strictly in accordance with the right boot and shutdown sequence as to avoid sudden sudden load plus or minus loads, UPS power supply voltage output fluctuations, leaving the UPS power does not work properly. (4) prohibits the frequent closing and opening the UPS power supply, UPS power generally require close Wait at least 6 seconds to turn on UPS power supply, otherwise, UPS power supply may enter the "boot failure" of the state, that neither UPS power supply into electricity output, nor the state of the output of the inverter. (5) prohibits the use of overload, manufacturer recommends: maximum load of UPS start preferably within 80% of the control, if the overload to use, in the inverter state, often the breakdown of the inverter transistor. Proved: For most UPS power supply is concerned, its load control in 30% to 60% of rated output power range is the best way to work. (6) UPS power supply regularly carry out maintenance work: remove dust inside the machine, measuring the voltage of the battery pack, replace defective batteries, check the fan functioning and detect adjust UPS parameters. Maintenance Precautions UPS power float feature article. (1) float voltage battery float current should satisfy compensated battery self-discharge current and the need to maintain the oxygen cycle. Lead-acid battery float voltage according to the following empirical formula: float voltage = open circuit voltage + polarization voltage = (hydrometer +0.85) V + (0.10 ~ 0.18) V VRLA battery electrolyte specific gravity of 1.30g / cm3, ie open circuit voltage of 2.15V, so the single battery float voltage takes 2.25 ± 0.02V / a (25 ℃). Deviation (2) terminal voltage (static and dynamic deviation deviation) has two valve-regulated battery terminal voltage deviation, one is standing state voltage deviation, namely open-circuit voltage deviation, such deviation should not exceed 20mV; Second, the dynamic bias, namely floating state deviation, the deviation in the initial float into a larger operation, operation will gradually decrease after two to three months. This is because the initial operation oxygen cycle resulting composite state is not stable, with increasing operating time, oxygen circulation composite state will become more stable, the terminal voltage deviation decreases. Therefore, the terminal voltage deviation float operating conditions, greater than the static state. When the level changes, the deviation is changing, the higher the average float voltage deviation increases, whereas deviation decreases, but disproportionate. No direct relationship between the level of the remaining capacity of the battery terminal voltage of the battery float operating state, it is difficult to judge from the battery terminal voltage is high residual capacity, low voltage end of its remaining capacity is small.

Maintenance-free design: APC UPS Series VRLA batteries have good oxygen circulation composite capabilities. Oxygen generated during charging almost completely absorbed, without the need to add water when used, and without measuring the density of the electrolyte. High energy density: As a result of poor design and liquid tight assembly process, the volume of APC UPS Series VRLA battery specific energy and weight greatly increase the specific energy. Low self-discharge: APC UPS Series VRLA batteries due to the high purity of the raw materials and additives, self-discharge rate of the battery when not in use or in storage is greatly reduced, self-discharge rate of less than 3% / month deep discharge. Good recovery performance: APC UPS Series VRLA batteries using a special electrolyte formula, deep discharge after a good recovery.
