1. Introduction 1.1 System performance TM TM A MGE Galaxy 9000 uninterruptible power supply (UPS) delivers 3-phase power with the following characteristics: – stable voltage (±0.5 % under steady state conditions and +/-5% under transient conditions for load step changes of 25 to 100 % or of 100 to 25 %); – stable frequency (±0.05Hz without Mains 2); – or frequency synchronized with Mains 2 to 50/60 Hz ±2 Hz (value may be configured in 0.25 Hz steps); – free of micro-breaks and outages for the

Introduction Operation with Mains 1 down (figure 12) In the event of a Mains 1 failure or Mains 1 voltage outside specified tolerance of –10 % in amplitude (–15 % optionally), the rectifier-charger stops and the battery supplies the necessary backup power to the load via the inverter. The battery, float- connected between the rectifier-charger and the inverter, discharges during this operating mode. The green "load protected" light 5 on the control panel is on. The user is warned of battery o

Introduction Operation with Mains 1 restored (figure 13) When Mains 1 power is restored or its voltage returns to within specified tolerances, the system automatically returns to its normal operating mode described above (on the condition it did not reach the end of battery power). If the end of battery power was reached (with the resulting inverter shutdown), the RC restarts automatically, but the inverter must be restarted manually, either locally or remotely in systems equipped with a r

Introduction Installation with an engine generator set (figure 15) If a stand-by generator is included in the installation, it is generally started automatically in the event of a Mains failure and connected to the main low voltage switchboard. It is disconnected when Mains power is restored. With such a system, the required battery time may be reduced to the time necessary for starting and bringing on line the stand-by generator. The battery supplies power to the inverter during the tr

Introduction Frequency converters without redundancy – in the event of a shutdown, the load is no longer supplied with power; – in the event of a major transient overload (greater than 160 % of the rated load), the inverters will current limit to 160 % of their rated current for 1 second before stopping; – in the event of a small but extended overload (i.e. a continuous level of power exceeding the full rated load), the inverters will continue to supply power for a period depending on the ma
