New power supply modules SINAMICS G120 PM240-2 by Siemens

siemens logo1In November Siemens presented new power supply modules SINAMICS G120 PM240-2 for frame sizes FSD and FSE with the power range up to 55 kW.

New power supply modules PM240-2 with the frame sizes FSD and FSE replace previous generation of power supply modules PM240 2 for frame sizes FSD and FSE. Besides, they extend application field of SINAMICS G120 converters including electric power supply voltage 220V (3AC 220V) and 500 – 690V. New power supply modules provide high specific power for each frame size with smaller housing dimensions; they can be installed side-by-side without power reduction. For example, frame size FSD of new PM240-2 modules is 1/4 narrower than mounting dimensions PM240, and they include more wide power range – up to 37 kW, instead of 30 kW by PM240 of the corresponding frame size FSD.

Main characteristics:

  • Voltage, power: 3AC 200 - 240 V up to 30 kW, 3AC 380 - 480 V up to 55 kW, 3AC 500 - 690 V up to 55 kW
  • Protection: IP20/UL;
  • High specific power;
  • Side-by-side installation without reducing power: reducing costs due to the space saving in the control cabinet;
  • Optimized connection on the side of the line, motor and breaking resistor;
  • Optimized ventilating unit;
  • Built-in surge protector, class А;
  • Optimized properties of the closed-loop control system: increased reliability and resistance;
  • Safety functions: for converters with frame sizes FSD-E function STO (up to SIL3/PLe) can be activated through the terminals;
  • Improved environmental conditions: higher protection level allows avoiding failures, caused by pollution;
  • Longer length of motor cables: shielded cables - 200m, unshielded cables - 300m
