Here are some of the most frequently asked questions about MARSRIVA products and services.
Usually 1-3 years, the specific warranty period is subject to the purchase contract or provided by the seller.
Online UPS has communication interfaces and can be connected to computer and use software to monitor the working status of UPS. Line-interactive UPS can only use software if it has the communication function with a communication interface.
If the UPS has an abnormal issue or a fault code is displayed on the screen, please first check the troubleshooting table in the manual and try to solve the problem according to the processing steps. If the problem cannot be solved, please contact our after-sales team, as well as your seller and local supplier.
The service life of the UPS battery is generally 3-5 years, but it will also be affected by factors such as ambient temperature and the depth of charge and discharge cycles. If the battery has been used for a long time or has undergone a large number of charge and discharge cycles, its capacity will gradually decrease, and it may be necessary to replace the battery.
UPS will generate some noise during operation, mainly due to fan cooling and internal circuits. When UPS is running, the buzzer will also work, but most UPS have a mute function to disable the buzzer. In general, the noise of home UPS is relatively low and will not have much effect on normal use.
In general, you can choose a UPS based on the following points:
1. Power capacity: Choose a UPS with the rated power that is greater than the total load power you need to connect. In daily use, the optimal UPS load ratio is approximately 50%-70% of the rated power.
2. Output voltage: Please confirm the UPS output voltage you need. For example, Single-phase 220V, Single-phase 110V, Three-phase 400V(P-P)/230V(P-N), etc.
3. Output waveform: If your device requires pure sine wave power input, please choose a Line-interactive UPS with pure sine wave output or an Online UPS.
4. Loads type: If you need to power gaming computers, servers, and other devices that require high-quality power input and are sensitive to transfer time when UPS switch to battery mode, it is recommended to choose an Online UPS. If you need to power general office computers or ordinary household appliances, choose a Line-interactive UPS.
5. Backup time: UPS is divided into two types according to the battery configuration/connection: Standard UPS with built-in batteries and Long-backup UPS that requires external batteries.
Standard UPS generally able to provide backup time within 10min at half load and within 4min at full load. If your backup time requirement is greater than the ability of Standard UPS, it is recommended to purchase a Long-backup UPS and purchase batteries of appropriate capacity as needed.
First and foremost, the technical topology of them is different. In AC/Line mode, Line-interactive UPS uses bypass for output and has certain voltage stabilization and filtering functions. While Online UPS uses online double-conversion technology, there is a double conversion process of AC-DC and then DC-AC when working in AC/Line mode. It has stronger voltage stabilization and filtering capabilities, protects the loads from the interference of the utility, and outputs high-quality electricity.
Secondly, Line-interactive UPS is simple product and has no setting options, while Online UPS has more settable options to suit different usage requirements.
In conclusion, Online UPS works better and is more advanced, while Line-interactive is simple but economical.
UPS can provide uninterrupted power during mains failures, ensuring the normal operation of equipment and preventing data loss and business interruptions. At the same time, it can also play a role in stabilizing voltage and filtering when the mains power is supplied, ensuring that equipment receives a stable power source.
