Sine wave UPS 500 + 40Ah (300/500W) 3SR500WA40

Uninterruptible power supply for home and business

The sinusUPS 500 with a 40Ah battery is a reliable solution providing continuous power in the event of a power failure. Thanks to the use of pure sine wave technology, the device is ideal for powering sensitive electronic equipment such as central heating boilers, circulation pumps, computers or automatic gates. The built-in 40Ah AGM battery guarantees sufficient backup time, protecting against data loss and downtime.

Universal application and functionality

This device combines the functions of a DC/AC converter, UPS switch, voltage stabilizer and battery charger. Thanks to this, it not only protects against voltage drops, but also stabilizes it and takes care of proper battery charging. A color display provides information about the most important operating parameters, such as battery level, input and output voltage and load. The "line-interactive" type power supply can also reverse the voltage polarity at the output during switching to battery power – important in some installations.

Safety and reliability in every detail

The design of the sinusUPS 500 power supply has been designed with user safety in mind. It has a number of protections against overload, short circuit, over- and undervoltage and battery discharge. The device housing allows for both wall and floor mounting – adapting to the individual needs of the user. The high efficiency of the device (over 92%) translates into minimal energy losses during operation. The use of an AGM battery ensures long life and maintenance-free operation. Thanks to the pure sine wave, the power supply can be used for inductive devices such as pumps or motors – where standard UPS power supplies may fail.
