If a mains failure continues beyond the backup time of the UPS, the UPS shuts
down to avoid a total discharge of the accumulators. As soon as the mains
power supply returns, the UPS automatically turns on again, supplies electricity
to the appliance and controls the charging of the battery bank.
Prominent performance features of the MTD series are:
– Short switching period to backup mode in the event of a failure of the pri-
mary power supply.
– Real sinus-wave voltage on UPS output, low distortion factor.
– Powerful communication interface (RS232-interface).
