The UPS systems of the AEG HE line use IGBT technology with a high
changeover frequency in order to allow a low distortion of the current re-
injected into the supply line, as well as high quality and stability of the
output voltage. The components used assure high reliability, very high
efficiency and ease of maintenance.
3.1 TYPOLOGY
The UPS systems of the AEG HE line are on-line, double conversion;
the inverter included in the UPS always supplies energy to the load,
whether mains is available or not (according to the battery autonomy
time). This configuration guarantees the best service to the user, as it
supplies clean power uninterruptedly, ensuring voltage and frequency
stabilization at nominal value. Thanks to the double conversion, it makes
the load completely immune from micro-interruptions and from excessive
mains variations, and prevents damage to critical loads (Computer -
Instrumentation - Scientific equipment etc.).
OUTPUT VOLTAGE PRESENT
The line connected to the UPS output is energized even during mains
failure, therefore in compliance with the prescriptions of IEC EN62040-1-
2, the installer will have to identify the line or the plugs supplied by the
UPS making the user aware of this fact.
