4 - CHARACTERISTICS

High levels of supply stability

The system provides a filtered, stable and reliable voltage (On Line double conversion VFI technology in

accordance with European standard IEC62040-3) with filters for suppressing atmospheric and mains borne

disturbances.

The On Line technology provides the maximum protection for the connected loads. The double conversion

stage filters and stabilises the input voltage, and then reproduces it free of any disturbances such as

overvoltages, variations in frequency and voltage, noise, etc.

The IEC62040-3 standard defines this technology as VFI (Voltage and Frequency Independent), meaning that

the output voltage and frequency are completely independent of any variations or disturbances caused to the

incoming mains supply.

High degree of protection against current surges (6KV in accordance with EN61000-4-5)

The GREEN POINT range has been tested by subjecting them to massive overvoltage and current surges on

the input. The current surge used has a leading edge of 1.2 microseconds and a trailing edge of 50

microseconds, with the maximum energy of 300 Joules. The standard (EN61000-4-5) states that these current

surges can reach up 6kV.

High levels of reliability and redundancy

Modular power supply: parallel connection

Maximum reliability and availability from the power supply, with the possibility to connect up to 8 systems in

parallel, used to provide either redundancy (N+1) or total power. The range has been specifically designed to

enable the user to install them in parallel with other systems of the same type, during the first installation or at a

later date (retrofit).
