BRAND:MODEL: SP1000 power 1KVA600W built-in 12V9AH lead-acid maintenance-free battery one year, the rest three years. DC VOLTAGE DC 24V input voltage 140-280VAC (wide voltage range) output voltage 210-230VAC (high precision voltage)  SHANPU SP1000 backup uninterruptible power supply are designed and manufactured with international technology, it has the advantages of high efficiency, beautiful appearance, advanced and reliable performance and so on. The microcomputer digitally controlled uninterrupted 220-volt AC power supply system is a high quality electronic product specially designed for users of computer systems and precision electronic instruments. In addition to ensuring a stable AC output, it can also be used to generate electricity immediately in the event of a sudden power failure in the AC market or when the instantaneous voltage is too high or too low to continue to supply the load, the transient high-voltage spikes and high-frequency noise signals on the power line are effectively suppressed and purified to the lowest level, so that the stored data and software programs in the computer system are not affected, to ensure the normal operation of computer systems and precision electronic instruments. Product features: SANKPH MT1000 UPS has super voltage-stabilizing function, suitable for people in areas with unstable voltage. Using Motorola CPU control; higher precision; input three-stage voltage-stabilized range 140-280VAC; 9AH Battery 1 Section; Standby Time 15 minutes (single PC) ; switching time ≤8ms; overload, overload, short circuit, shutdown automatic charging; temperature 0 °c-40 °c; Led and sound and light alarm. Product features: perfect and elegant design, adapt to a variety of high-end office areas improve the battery over-discharge protection function, so that users have no worries intelligent automatic sound and light warning function, so that users can safely and efficiently use the advanced automatic constant voltage, constant current charging function, can extend the battery life automatic frequency regulation, automatic short-circuit protection, output overload automatic protection using the United States high-standard UPS electronic integrated circuits and application of microcomputer control technology, when the city power outage directly start UPS, convenient for users to use the city power input high and low voltage automatic protection, while providing continuous stable power supply for users load using the original high-quality maintenance-free valve Lead acid battery, the electric power is durable and stable, and the operation reliability of UPS is improved effectively. Unattended function, battery under-voltage automatic shut-down protection, power back to normal automatic start.
