20-140 kVA Three Phase

The [e] series of UPS systems are genuine Double Conversion systems in accordance with VFISS111 (IEC 62040, Part 3) and continuously regulate supply voltage, protecting critical resources against mains disturbances. If a power failure occurs, supply to your sensitive systems continues without interruption from the battery for the defined battery operating period. Your equipment is also safely switched to mains supply via the internal electronic switching circuitry in case of overloads or system faults. Since these UPS systems generate virtually no mains repercussion, they are outstandingly suitable for operation in combination with standby generator sets, to permit bridging even of longer power failures.
