Ups uninterruptible power supply how to maintain?
5. Do not place the UPS in moisture and heat, do not be exposed to sunlight.
Shenzhen Renda Energy Technology Co., Ltd. is one of the independent companies focused on uninterruptible power supply (UPS) R & D, production and sales. It is committed to providing customers with perfect power supply solutions. Products include the backup machine 500VA to 200KVA high power and machine series, power UPS, power inverter, communication UPS, communication inverter, iron lithium battery UPS, etc., products used in power, communications, government, education, finance, Enterprises and other industries.
4. Should try to avoid frequent start and shut down UPS. Frequent opening and closing operation may lead to UPS failure to start, the correct operation is: when the UPS off, wait at least 6 seconds before restarting.
3. For UPS, do not connect loads such as fluorescent lamps. Otherwise, due to UPS technical performance indicators are not applicable, may cause damage to the UPS itself.
2. Because when the electricity is interrupted, the UPS output to rely on the battery power supply to support, so the correct use, maintenance of the battery pack is very important, with particular attention to the following matters:
Can not make the battery in the UPS over-discharge and open idle. Otherwise, will be in the battery cathode "sulfated" to increase the battery resistance, damage the battery charge and discharge characteristics.
UPS before use or battery after each discharge, the general need to charge the battery 10 to 12 hours, the charging time is not enough to make the battery in an inadequate state. At this time the actual capacity of the battery is much lower than the nominal capacity of the battery.
When the UPS is not used for a long time, it should be switched on for some time. For the backup UPS recommended every 1 month, so that UPS work in the inverter working state at least 2 to 3 minutes in order to activate the battery to extend the battery life.
When charging, should try to avoid over-current and over-voltage charging, the use of constant current charging better.
1. When using the UPS should pay attention to the UPS parameters, such as the input voltage range, output waveform, output power, the longest power supply time, conversion time, and battery brand, machine noise, volume, weight and other parameters. All kinds of UPS should not be fully loaded work, should retain more than 20% of the power margin, the best load control in the UPS rated output power between 40% to 60%. For example, if only one ordinary computer to use, a 500W or so about the UPS is enough.
