Marsriva MR-UF800 800 VA
 | Outdated Product A relatively compact and inexpensive interactive uninterruptible power supply (UPS) with an approximate sine wave output, built-in batteries and stabilizer function. Positioned as a product in the basic price category of 2023, designed to create a temporary emergency power supply system for low-power household and professional equipment. The Marsriva MR-UF800 uninterruptible power supply is equipped with two standard EU Type F connectors (Euro socket), a full range of short circuit/overload protection, an audible alarm and an interference filter. The rated power of this model is 480 W, maximum 800 W. At a load of 50% of the rated power (240 W), it provides up to 5 minutes of stable operation and this time will be quite enough to complete the work correctly. Ideal for working with switching...computer power supplies, incl. with active/passive power factor correction. Will cope with the task of temporary emergency power supply of telecommunications equipment, small servers and workstations, a wide range of automation equipment, video surveillance systems, emergency LED lighting, etc. The UPS is equipped with one built-in lead-acid gel (AGM) battery with a voltage of 12 V and a capacity of 7 Ah. In addition to quickly switching to battery power (no more than 6 ms), this UPS can perform the functions of a voltage stabilizer (AVR, from 140 to 300 V).

Stable power supply
The Marsriva MR-UF800 is an interactive uninterruptible power supply with a peak power of 800 volt-amps and a rated power of 480 watts. It also acts as an AVR voltage stabilizer: it is capable of equalizing 145 - 290 V into a stable 220 V, similar to a sine wave (approximation). The UPS can charge its battery from the mains, even when completely turned off.
Long service
Inside is a high-quality 12 amp-hour lead-acid battery that does not lose its capacity even after numerous recharge cycles. Charges from zero to one hundred percent in about 6 hours. The transition from wall power to battery occurs in just 6 milliseconds. Equipped with two standard Schuko sockets for a European plug.
Status indication
If you connect too powerful devices to the UPS, it will automatically turn off and indicate the Overload light. A fuse reliably protects against short circuits. The sound signal during battery operation can be turned off by briefly pressing the power button. Four LEDs indicate the remaining charge level.
When connected to the network, it is silent, but when it operates on its own battery, it naturally emits a characteristic electrical buzzing. The voltage stabilizer kicks in when the voltage drops below 210.
The only downside is that it's impossible to completely disable the sound signal. Every time the power goes out, be prepared to run and press the button to stop the beeping) Or perhaps find a technician to somehow disable the sound signal.
