Santak UPS

Instructions for using Santak UPS power supply (Part 1)

The use of Santak UPS power supply should first meet the requirements of input characteristics, followed by the requirements of output characteristics, and finally, the most important thing to pay attention to is correct operation. The correct use and maintenance of UPS have a significant impact on its service life. Under the premise of proper use and maintenance, the service life of a UPS is generally 5-10 years or longer. If used and maintained improperly, it may not be usable for several years. Especially the battery pack requires regular maintenance. Some units keep UPS personnel in storage for 2-3 years or even longer, and when they are released for use, they find that the batteries cannot be discharged with load, which not only brings inconvenience to use, but also increases unnecessary economic losses. Moreover, the price of batteries generally accounts for 1/3 of the overall price. If it is a long delay UPS, the price of the battery pack can exceed the “bare machine” price.

The use of Santak UPS:

1. Meet the requirements of input characteristics

It is best not to use UPS input network side in conjunction with other nonlinear high-power loads (such as large motors, neon lights, elevators, etc.). If the quality of the UPS input voltage is too poor, it may cause rectifier protection, control system misoperation, and in severe cases, UPS fault load power outage. For large and medium-sized UPS, if the power supply conditions are limited and the grid quality is poor, an isolation transformer can be installed on the input side of the UPS to ensure that the input voltage is within the specified range.

2. Meet the requirements of output characteristics

UPS is best operated within the optimal load range, with a load of 60% to 80% of the nominal capacity. When the load is too light, the efficiency of UPS decreases and the distortion rate of input voltage and current increases. When the load is too heavy, it is easy for the UPS to frequently switch to the bypass. If it is necessary to carry loads with high surge currents, the UPS should be downgraded for use. The nominal power capacity of UPS is closely related to the power factor of the load. Generally, the rated capacity of UPS is calibrated under the condition of linear load and power factor of 0.8. The load types connected to UPS have certain design requirements, so it is best to keep the load types within this range. Under normal mains power conditions, backup small capacity UPS operates on bypass power output and can only rely on input fuses for protection. If users do not pay attention to this point and overload during use, although the UPS can continue to work when the mains power is supplied, when the mains power is abnormally switched to battery power for inverter operation, the UPS will shut down due to overload protection, which can cause damage to the UPS and cause certain losses to users in severe cases. Therefore, special attention should be paid not to overload when using backup UPS. It is best not to connect UPS output terminals to other electrical devices without authorization, except for dedicated loads.
