Protect 1 LCD High efficiency transformerless UPS with 10 to 20 kVA and configurable phases: 3/3, 3/1, 1/1


Highly flexible and compact. Protect 1 LCD is a transformer-less UPS that combines high efficiency values with compact footprint and flexible configurations. Thanks to its full IGBT technology, Protect 1 LCD features low input THDi with almost unity input power factor.

The UPS is settable as 3/3, 3/1 or 1/1 and offers an adjustable range of recharging current up to 13 A. The system is an ideal power supply solution for small and medium critical applications when the power consumption, the footprint and the maintainability are key factors of choice.


Comprehensive UPS protection 打开

Online UPS topology, also known as double-conversion, provides reliable protection against all 9 kinds of power supply failures. It provides clean power thanks to connected loads that are constantly supplied from the battery.
