| Proper use and maintenance of UPS's Ten Secrets |
| Time：2018-10-03 Source： Views：2944 |
Shenzhen Shante UPS power supply is a famous brand of UPS power supply, namely uninterruptible power supply. It is a constant voltage and constant frequency uninterruptible power supply with energy storage device and inverter as the main component. Santak UPS power plays an important role in protecting your data and machine equipment from damage. Therefore, it is very important to correctly use and maintain Santak UPS. Many users are limited to the precautions in the product manual. In fact, it is necessary to run through the whole life cycle of UPS to maintain and use UPS reasonably. In order to ensure its normal operation and prolong its service life, attention should be paid to the following aspects in the use and maintenance:
1. choose reasonable installation position.
A good installation position is very important, place the UPS must have good ventilation effect, to be away from water, flammable gases and corrosives, the ambient temperature should be kept between 0 ~40 ~C, if it is disassembled and used at low temperature, there may be condensation of water droplets. Once the ambient temperature exceeds 25 degrees, the life of the battery will be reduced by half by 10 degrees. At present, the batteries used by UPS are generally maintenance free lead-acid batteries, and the design life is generally 7 years.
Sand UPS power supply should not be side-put, should maintain the intake and outlet air holes unobstructed; load and UPS power supply connection, the load must be closed, then wiring, and then turn on the load one by one, strictly prohibit the electric, copying machine and other inductive loads into UPS, in order to avoid damage. When UPS is connected to a special socket with an overcurrent protection device, the power socket used should be connected to the protective ground end; the UPS output may be energized regardless of whether the input power cord is inserted into a commercial socket or not. In order for UPS to have no output, the switch must be switched off and the supply of electricity will be cancelled.
2. first time charging skills
After purchasing the new UPS power, connect the UPS to the grid and charge it for at least 12 hours to ensure that the battery is fully charged. Otherwise, the actual capacity of the battery will be much lower than the nominal capacity of the battery. If UPS power is not used for a long time. Should start 24 hours every 2-3 months, let it charge and discharge, and let the UPS power supply in inverter working state for 2-3 minutes, to ensure the normal life of the battery. Once the UPS power supply is connected to the power supply, the battery group will be charged and the inverter will be turned on by pressing the boot button for more than 1 second.
3. UPS should not be idle for a long time.
Excessive discharge and long-term open circuit idle of the battery can increase the internal resistance of the battery and deteriorate its charge and discharge performance. For the long-term unused Shante UPS power supply, before restarting, let UPS power supply charge 12 hours after the recharge circuit in the machine, for the backup UPS power supply, it is best to keep the UPS power supply in inverter state every month for 2-3 minutes to activate the battery. In addition, it is necessary to strictly control the charging current of the battery must not exceed the maximum allowable charging current of the battery. Because excessive charging current will lead to shortened service life of batteries.
4. when using UPS, boot and shutdown sequence should be understood.
The correct turn-on sequence should be to turn on the UPS to power it first, and then turn on each load, so as to avoid the damage caused by the instantaneous current impact on the UPS startup, turn off the reverse sequence should be the first to turn off the load and finally turn off the UPS. When the power supply is interrupted by UPS, you should save your data and data as soon as possible and then turn off the computer. Otherwise, using UPS power supply to work may lead to excessive discharge of UPS, thus shortening the service life of UPS.
5. avoid overload as far as possible. Use Santak UPS
When using UPS, we should also calculate the load size, to avoid overload or too small, too large load will make the UPS long-term work in overload state and shorten the service life of UPS; if the load is too small, the working circuit of UPS works in abnormal state for a long time, which is also harmful to UPS. Reasonable loads should be controlled between 50% and 80%. Practice has proved that the output load control of UPS is about 60%, and the reliability is the best. When the UPS overloads or inverter failures occur, it will switch to bypass mode. At this time, the UPS does not have the backup function, and the power used by the load is supplied directly through the power system.
6. AC regulator can be selected for use.
After using the UPS power supply, there is no need to add AC voltage stabilizer. If it must be added, it should be in the front of the UPS, that is, the city electricity first through the AC regulator, then through the UPS, and then to the load.
7. battery equalization charging skills
Valve-regulated lead-acid batteries (VRLAs) currently used in many UPS power supplies have been called maintenance-free batteries from the start, giving users a misconception that they seem to be both durable and completely maintenance-free. Under such a misleading situation, many users have not maintained and managed the batteries since they were installed. Batteries in UPS power supply should be charged equally when they encounter the following conditions: excessive discharge causes the terminal voltage to be lower than the battery specified calibration voltage. For small sealed lead-acid batteries of 12V, the discharge voltage is 10.5V; for 24V, the final discharge voltage is 21V; for 96V, the discharge voltage is 85V. The battery is not charged in time after discharge, and the battery is not used for a long time. Battery interruption, continuous floating battery, nearly half of the capacity of the battery.
8. try not to use diesel generators.
UPS is not suitable for diesel generator power supply, because its frequency is often unstable and unstable, which affects the normal operation of UPS.
