Model overview based on user reviews
The CyberPower CP900EPFCLCD 900 VA is an interactive UPS designed for both functionality and aesthetics. It features a clean sine wave output, making it suitable for sensitive equipment like modern automation systems and computers with active PFC. The UPS offers quiet operation, with the option to turn off the buzzer and display, making it ideal for quiet environments like bedrooms. It provides accurate voltage delivery and includes a display that shows essential metrics such as power, runtime, and voltages. The UPS has six Schuko-type sockets, all connected to the battery, and offers protection features like overload protection, noise filtering, and data line protection. While the switchover time to the battery is slightly longer than the stated 4 ms, this is common among many UPS models. The device is compact, with dimensions of 230x100x275 mm, and weighs 7.1 kg. It also includes USB and Ethernet protection, adding to its versatility. However, users may notice an initial odor, which dissipates after airing out. Overall, the CyberPower CP900EPFCLCD is a reliable and efficient UPS for various applications.
Pros
Cons
In the screenshot, there is a switch to battery. (Accordingly, the signal form from the mains before the spike, and what the UPS delivers from the battery afterward). It can be seen that the main switch happened in 17 ms, if not being too picky. Sometimes the switching process doesn't distort the form as much, but in terms of time, it's always roughly the same. On idle, without charging, it consumes about 4 W. Unfortunately, there was no way to test the stabilization. - Quiet, doesn't whistle with chokes, doesn't hum with the fan (hums from the batteries, but very quietly) - Doesn't heat up - Buzzer and display can be turned off. It's nice that it doesn't scream with super bright LEDs or boast in other ways. - Very clean sine wave output - Accurately shows voltage and delivers a precise 230V when powered by the battery, with the ability to choose stabilization accuracy from the network - Decent, although slightly awkwardly translated software. Includes various schedules, disconnection based on remaining charge, transition voltage and stabilization settings, can work as an electricity meter, etc. - The display also shows power, runtime, voltages - Well, USB ports, Ethernet protection, also a nice touch - The switchover time to the battery is not exactly 4 ms, but that's common with many UPS. - Initially, it emits a strong odor. It's not overwhelming, but you can't get used to it; you're always aware that there's a UPS in the room. It's better to leave it somewhere else to air out for a couple of days. Many UPS units have a similar smell. |
