::::::::::::::::::::::::::::::::::::::::::::::::::: THE SM32 ADVANTAGE :::::::::::::::::::::::::::::::::::::::::::::::::::::::::
 
 

SM32 is suitable to power supply both single and multiple inverter systems parallel connected to a common DC link. The precharge of the leveling capacitors, which can be set via internal dip-switches, is performed by partializing the Mains voltage via an input thyristor bridge. A diagnostic circuit allows to set the delay time for the switching off of the power thyristor during a power dip.

 
 
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: FEATURES :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
 
 
  • Selection of the delay time for the thyristor switching off during a power dip
         (7 times, from 1.1 to 7.7 ms ± 10%) which can be selected via the dip-switches.
  • Selection of the undervoltage threshold according to the power supply
         voltage (3 voltages: <_370 VDC, <_ 300 VDC and <_ 80 VDC) which can be
         selected via the dip-switches
  • Selection of the precharge time for the leveling capacitors (5 times, from
         2 to 18 seconds ± 15%), which can be selected via the dip-switches
  • Selection of the power supply mains frequency: 50 or 60 Hz
  • Enabling, via the terminal strip, of the precharge delay.

    Inputs/Outputs
  • Relay outputs: 1 drive OK contact (normally open, closed after the precharge)
  • 2 digital outputs: MLP signal (sum of the precharge and of the set
         undervoltage threshold) and ML signal (Mains voltage monitoring).

    Environmental Conditions
  • Ambient temperature: from 0 to 55°C, if the temperature is higher than
         40°C, reduce the current by 1.25% every K.
  • Humidity: from 5% to 85%, 1 g/m3 up to 25 g/m3 without condensing or ice
         formation.
  • Altitude: up to 1000 meters on the sea level; if such value is exceeded, the
         current has to be reduced by 1.2% every 100-meter increase.
