Siemens G120P-PM230 Power Modules
0.37 kW to 90 kW
PM230 Power Modules are designed for applications involving pumps, fans and compressors with a quadratic characteristic. They do not have an integrated braking chopper (single-quadrant applications).
The PM230 Power Module only generates low line harmonics and apparent power losses. In addition to the energy-related advantages, the environmental stress is also reduced.
- Line harmonics are reduced significantly.
- The limit values of EN 61000‑3‑12 are complied with for RSCE > 250.
RSCE is the short-circuit power ratio Ssc line/Sconverter acc. to EN 61000‑3‑12 and is identical to RSC acc. to IEC 60146‑1‑1 in the case of three-phase devices.
- Additional components such as line reactors are not required and it is not permissible to use them. As a consequence, low envelope dimensions are obtained for space-saving designs.
- The active power component is very high, i.e. the devices consume less current from the supply for the same drive power. As a consequence, smaller supply cables can be used.
Frame sizes FSA to FSF of the PM230 Power Module in degree of protection IP55 are available with integrated line filter class A for installations acc. to Category C2 and in accordance with EN 61800‑3. The PM230 Power Modules with integrated filter class B that are available as an alternative also comply with the conducted interference requirements for Category C1 in accordance with EN 61800‑3.
