Mecer 850VA Line Interactive UPS can charge up to 90% in battery capacity within a 4-6 hour period. This Mecer 850VA Line Interactive UPS provides built-in protection against Power overloads, discharge and overcharging of the device.

The Mecer 850VA Line Interactive UPS is an 850VA Line Interactive UPS designed to provide reliable power protection for your electronic devices. With a power capacity of 850VA or 480W, the Mecer 850VA Line Interactive UPS offers sufficient backup power to keep your equipment running during power outages or fluctuations. The Mecer 850VA Line Interactive UPS features a 220VAC input voltage and provides a stable 230VAC ± 10% output voltage.

The Mecer 850VA Line Interactive UPS is similar in operation to a standby UPS, but with the addition of a multi-tap variable-voltage autotransformer. This is a special type of transformer that can add or subtract powered coils of wire, thereby increasing or decreasing the magnetic field and the output voltage of the transformer. This may also be performed by a buck–boost transformer which is distinct from an autotransformer, since the former may be wired to provide galvanic isolation.

This type of Mecer 850VA Line Interactive UPS is able to tolerate continuous undervoltage brownouts and overvoltage surges without consuming the limited reserve battery power. Mecer 850VA Line Interactive UPS instead compensates by automatically selecting different power taps on the autotransformer. Depending on the design, changing the autotransformer tap can cause a very brief output power disruption, which may cause Mecer 850VA Line Interactive UPS equipped with a power-loss alarm to “chirp” for a moment.

This has become popular even in the cheapest UPSs because it takes advantage of source, and the battery is the secondary. When the line power is operating, the inverter/converter charges the battery; when the power fails, it operates in reverse.
