MD-1000I / MD-2000I / MD-3000I System Function
MD Series 58
5.5 Inverter - Excessive Internal Temperature
Raised temperatures in the UPS automatically set off the bypass mode. The
UPS switches back over to normal operation, once the temperature has re-
turned to normal. If excessive termperatures occur while the energy supply is
abnormal, the audible alarm sounds and the LEDs indicate malfunction. The
UPS ceases to supply the equipment with power.
If a power outage exceeds the duration of the UPS' power supply, the UPS will
shut down to protect the battery from deeply discharging. When the mains
comes back on, the UPS kicks back on, energises connected equipment and
controls the recharging of the battery/battery string.
The UPS has many outstanding features:
– Absolutely no interruptions or change in signal if a primary power source
outage occurs
– Pure sine wave output. The quality of the output voltage is significantly bet-
ter than that of the mains input.
– Processor-controlled bypass
– Input Power Factor Correction (> 0.95).
– LCD status and operating display
– Excellent Power Factor of 0.8
– Powerful and extensive communication interfaces
– RS-232 is standard
– USB is standard
– Programmable switch contacts are standard.
– NOT-HALT EPO contact is standard.
