Qoltec Uninterruptible power supply Pure Sine Wave UPS | 500VA | 350W | constant phase | Grey

A reliable source of energy

The Pure Sine Wave uninterruptible power supply is of the highest class and made of high-quality materials. It is reliable when it detects a power outage, it automatically switches to battery mode, thus not allowing a power drop in the connected devices, allowing them to continue working. A characteristic feature of the power supply is the production of an alternating voltage at the output with a purely sinusoidal waveform, that is, the same as in an electrical socket.

Compatible with any type of power supply

Qoltec's uninterruptible power supply combines multiple features to guarantee uninterruptible power to furnaces, CO pumps and other home appliances that require continuous power. In addition, it offers:
- constant phase,
- long backup period,
- line - interactive - when there is a power outage, the power supply switches to battery mode,
- high charging current,
- pure sine wave - that is the basis of safety and guarantee of compatibility with any type of power supply,
- modular CPU - controlled circuit,
- AVR function (automatic voltage regulator),
- protection against overload, short circuit, voltage drop, battery overcharging and discharging, overheating and reverse battery connection,
- powerful high - power transformer and specially designed heavy-duty circuit,,
- double conversion - stable power supply is provided,
- 3-stage charging current selection,
- efficient heat dissipation,
- two output sockets.

Phase always in a fixed place

The big advantage of the Pure Sine Wave power supply is the constant phase, this means that regardless of the method of power supply, whether it is from a battery or an outlet, the phase is always in the same place.

Functional LED display

The built-in LED display guarantees free management of the device operation. It keeps you informed about the device's status and parameters such as : battery capacity, load, overload, battery status, mains access and input/output voltage, making it easy, fast and reliable to work with the device. The LED display and built-in audible alarm inform you of :
- low battery voltage,
- battery discharge,
- 120% overload,
- 120% overload.

Protections

The power supply has been designed in accordance with all required standards and quality control system. Equipped with a number of protections, it guarantees full protection of connected devices. By following the instructions in our manual, you can enjoy trouble-free operation for many years.
