The models of the UPS-1000 series belong to the line-interactive uninterruptible power supplies with continuous operation and long reserve time.

Their operating principle is based on:

• The conversion of stored energy from external batteries into alternating current voltage of industrial frequency. The output voltage form is a pure sine wave.
• The main purpose is to power household and industrial equipment that is sensitive to the shape of the input voltage (boiler equipment, automation systems, etc.).
• The device is equipped with an automatic voltage regulator (AVR).
• The built-in stabilizer ensures proper load power supply during increased or decreased network voltage without switching to battery operation mode.

The device uses a multi-stage intelligent battery charging circuit that automatically selects the charging mode for the batteries.

Features:

• Galvanic isolation of the battery from the AC network.
• Protection against reverse polarity when connecting the battery.
• Battery protection from short circuits (fuse 90A).
• Intelligent multi-stage battery charger for connected external batteries.
• Selection of battery type (lithium LiFePO4, acid AGM or GEL).
• Adaptation of the charger to the battery type.
• Selection of the charging current for the battery from three fixed values, according to the manufacturer's recommendations.
• Low noise level (adaptive fan speed control).
