In these environments, many devices, such as servers, manufacturing machinery, medical instruments, and communications equipment, are highly sensitive to power outages. This type of system provides stable three-phase power and balances the load across each phase to ensure voltage stability, preventing equipment damage due to power fluctuations or interruptions.
For mobile applications, such as outdoor activities, emergency vehicles, or temporary construction sites, mobile three-phase UPS systems are especially important because they provide power in the event of a lack of stable grid power. This capability ensures that critical equipment can operate safely in any location, maintaining operational continuity and efficiency, and preventing data loss or production interruptions due to power outages.
The new NTN-5K from MEAN WELL, distributed in Spain and Portugal by Electrónica OLFER, is a 5000W sine wave inverter for off-grid applications. It boasts high reliability and features an integrated AC charger and UPS (UPS) function. Battery backup is also included. It is ideal for homes, offices, vehicles, boats, remote mountainous areas, and other off-grid outdoor applications.
In addition to single-phase use, three NTN-5K units can be combined to provide a four-wire, three-phase AC output (3Ø4W). This configuration can be applied to four-wire, three-phase equipment (L1/L2/L3/N) or used to connect separate phase voltages (L1/L2/L3-N) to single-phase equipment.
The differences for each phase are configured using DIP switch SW1, as described in the following table:
Additionally, for applications using 110Vac/220Vac three-wire single-phase systems, you can also use the following wiring method and DIP switch configurations. However, please note that if you are connecting AC power supplies, they must be independent. Otherwise, an internal short circuit may occur.
