The inverter is a device used to protect electrical equipment against hazards (voltage drop, overvoltage, voltage peak, lack of voltage, frequency variation, electrical pollution, etc.). It's a box placed as an interface between the distribution network (EDF current) and the equipment to be protected (computer equipment, servers, agricultural machinery, industrial machinery, collection equipment, etc.). It is also composed of one or more batteries in order to give autonomy to the equipment to be protected in the event of an interruption of the distribution network.

SINUS ELEC is a RIELLO partner in the distribution of inverters for all ranges.

ONLINE

ONLINE (VFI) :

It is the most advanced technology. Applications connected to the UPS are permanently powered by the rectifier/inverter pair. This binomial also provides voltage and frequency regulation at the output of the device. The switchover to battery operation is instantaneous (0ms).  In case of rectifier/inverter failure and/or overload, the unit switches to automatic by-pass. In this case, the load is fed directly from the mains.

LINE INTERACTIVE

 

LINE INTERACTIVE (VI) :

OFF-LINE system + one AVR stabilizer. The Auto Voltage Regulator corrects voltage variations by bringing them within the tolerance of the UPS. When the voltage cannot be corrected by the AVR, the inverter takes over and ensures the continuity of the current from the battery. A delay of 2 to 10ms is possible. This solution is therefore independent of the input voltage.

OFF-LINE (VFD)

OFF LINE (VFD) :

In normal mode, the inverter is in passive standby. The inverter only operates when the energy is no longer distributed by the grid. During a power outage, there is a transfer time of 2 to 10ms. The delay comes from the time it takes for the direct current stored in the battery to be transformed into distributable alternating current. The output voltage is dependent on the mains voltage and frequency.
