Analysis of the CBR QTM 1500T 4F LCUC UPS for basic protection
This uninterruptible power supply system of the line-interactive type is designed to protect devices in home and work environments. With a power rating of 1500 VA and 900 W, it integrates key functions such as stabilizing the mains voltage and providing brief energy backup. Its design prioritizes functionality and a compact size. 🔌
Main features and operation
The unit corrects minor variations in electrical voltage using its stepped AVR technology, which avoids using the battery for these adjustments and preserves it. It has four connectors that filter surges and a USB port that allows PC software to monitor its operational status. An LED screen informs the user about the operating mode and the remaining charge level.
Key specifications:- Capacity: 1500 VA / 900 W to protect sensitive equipment.
- Stabilization: Automatic AVR that adjusts voltage without resorting to the battery.
- Connectivity: Four outlets with surge filtering and a management USB port.
- Interface: LED screen that displays operation and load data.
It is an economical option to back up equipment against brief power supply failures.
Practical results and autonomy
When testing the device, it is verified that it effectively handles voltage corrections, switching between the taps of its transformer quickly and without interrupting the output power. However, the battery runtime is modest. With a demand close to its nominal 900 W, autonomy is reduced to just a few minutes, enough to save documents and shut down the system orderly, but not to continue operating for an extended period. The transition to battery mode is smooth and keeps the most sensitive devices running.
Points to consider in the tests:- Corrects mains fluctuations quickly and without interruptions.
- Battery duration with high load is short, only minutes.
- The switch to backup is instantaneous and stable for connected hardware.
Conclusion on recommended use
This UPS fulfills its essential purpose: providing an energy buffer and stabilizing voltage. It is ideal for protecting a desktop computer, a monitor, and some peripherals, offering a safety margin against momentary power outages. It is not designed for servers or critical applications that need to operate for extended periods. Its main advantage is the affordable cost, positioning it as a practical solution where a more complex or higher-power system is not required. If you expect it to keep a gaming PC with two screens on during a storm, know that the session will turn into a very brief race against time. ⚡
