INV — industrial single-phase and three-phase inverters
Country: France · Model: INV
The INV inverters convert the DC voltage of a station battery into single-phase or three-phase AC with THD below 2 %. They power critical loads at substations, in telecom and in production where a DC bus already exists.

Description
The IGBT power stage works with high-frequency PWM, so the output filter is compact and the voltage waveform is close to a pure sine wave. The inverter withstands an overload of 150 % for 1 min and 110 % for 2 h, which is enough for starting motors and energizing transformers. The built-in static bypass transfers the load to the backup mains on overload or fault, and the manual bypass lets the inverter be serviced without de-energizing. In line-interactive mode efficiency exceeds 98 %, and in online mode it is above 93 %. The smallest 300 VA model is powered from 48 V DC, delivers a sine wave and mounts in a 19-inch rack.
How to choose
The rating is determined by the power of the critical consumers, taking inrush currents into account, and the input voltage by the station battery. Line-interactive mode is chosen when losses matter, and online mode when the load must not see any switching. If the station battery still has to be charged, an RCRFn rectifier-charger for 24, 48, 110 or 220 V DC is installed as a pair to the INV.

FAQ
What overload does the INV inverter withstand?
150 % for 1 min and 110 % for 2 h, which covers the inrush currents of most loads.
What is the efficiency of the industrial INV inverter?
More than 98 % in line-interactive mode and more than 93 % in online mode.
Is there a 48 V INV inverter for a rack?
Yes, the 300 VA model is powered from 48 V DC, delivers a sine wave and is installed in a 19-inch rack.
Why does an industrial inverter need a static bypass?
It instantly transfers the load to the mains on overload or inverter failure, and the manual bypass is needed for servicing without de-energizing.
What is the output voltage distortion of the INV inverter?
Output THD is below 2 %, so the inverter powers measuring circuits and relay protection electronics.
