Altitude affects the reliable operation of UPS power supply. With the increase in altitude, high altitude and cold weather pose challenges to the use and maintenance of UPS power supply. The insulation performance of UPS power supply becomes worse, and the effect of air-cooled heat dissipation becomes worse. What are the effects of using UPS power in high altitude areas?

What should I pay attention to when using UPS power supply in high altitude areas?

Generally, the working environment of UPS power supply parameters will show a description of the altitude: "Altitude <1000m (the power is reduced by 1% for every additional 100m) up to 4000m". Why does the change of altitude affect the performance of UPS power supply?

When using UPS in high altitude areas, we must consider the problem of equipment derating. During the operation of electronic equipment, the temperature maintenance of UPS power equipment is an important factor related to smooth operation. After the altitude exceeds 1000 meters, the impact on UPS has three aspects:

1. The air pressure decreases and the capacitor is slightly deformed, which causes the capacity change and affects the output power of the UPS uninterruptible power supply;

2. The altitude is too high, the air density drops, the same fan speed, but insufficient ventilation, resulting in insufficient heat dissipation capacity, then full load will appear thermal overload, the power device will stop running due to too hot, affecting the load protect.

3. In high-altitude areas, because of the low absolute humidity, large temperature difference, and strong solar radiation, it will accelerate the aging of UPS equipment materials, thereby affecting the performance of electrical equipment.

With the increase in altitude of UPS power supply in plateau areas, the power and backup time of UPS power supply will decrease. When we use UPS power supply in plateau areas, we should pay attention to the choice of brand when choosing UPS power supply. Some uninterruptible power supplies are not supported for use in plateau areas.

Electronic components are affected by high altitude factors, and there are common technical characteristics for derating. We don't need to consider this issue in the range of altitudes less than 1000 meters. For every 1000 meters above sea level, we should consider the 10% derating of the equipment.

All electrical and electronic equipment is generally matched according to about 80% of the operating power consumption when the equipment is running. Therefore, in the early stage of equipment selection, we should reasonably calculate the actual power consumption of the equipment to match the corresponding Golden Samurai UPS. The model of the battery for the power supply.

Altitude varies greatly. When selecting and using UPS power supplies, the altitude factor should be fully considered. When applied to high altitude areas, the following considerations should be taken:

①Select or customize UPS power products with large safety gaps to avoid internal ignition failures in the circuit.

②Under environmental conditions higher than the normal operating altitude, the UPS power supply should be derated to prevent UPS over-temperature protection.

In summary, altitude does have an impact on the use of UPS equipment. If you have a project that needs to use UPS power in high altitude areas, you must consider whether the selected brand can meet the requirements for use.
