The IS series is a range of off-grid inverters designed to convert DC voltage into a sinusoidal output voltage of 230 V AC / 50 Hz. A wide range of input voltages allows the inverters to be flexibly adapted to various power supply systems and energy sources. The units are housed in a 2U-high 19” rack-mount enclosure, suitable for installation in telecoms and power distribution cabinets. All connections, indicator lights and safety devices are located on the front panel, which significantly simplifies installation, operation and maintenance. IS inverter versions are also available with an additional 230 V AC input (by-pass), enabling the automatic supply of mains voltage to the output in the event of a loss of DC voltage at the input, thereby increasing the continuity and reliability of the power supply.
