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, environmental stressing is also reduced.

• Line harmonics are reduced significantly.
  • The limit values of EN 61000‑3‑2, EN 61000‑3‑12 or IEC 61000‑3‑4 are maintained for R_SCE > 250.
    R_SCE is the short-circuit power ratio S_sc line/S_inverter acc. to EN 61000‑3‑2, EN 61000‑3‑12 or EN 61000‑3‑4 and is identical to R_SC 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/UL Type 12 are available with integrated line filter class A for Category C2 installations 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.

Frame sizes FSA to FSF of the PM230 Power Module in degree of protection IP20 are available with integrated line filter class A for Category C2 installations in accordance with EN 61800‑3, or without an integrated line filter.

Frame sizes FSA to FSC of the PM230 Power Module in degree of protection IP20 Push Through variant are available with integrated line filter class A for Category C2 installations in accordance with EN 61800‑3, or without an integrated line filter.

In order to maintain EMC categories C2 (line filter A) or C1 table 14 (line filter B, conducted), the permissible shielded cable length between the inverter and motor is limited to max. 25 m (82 ft).

The permissible cable lengths between inverter and motor are limited. Longer cables can be used if output reactors are connected for PM230 (see load-side power components).

The line system configurations that are supported are symmetrical systems with grounded neutral point.

PM230 Power Modules do not support Control Units with Safety Integrated. Safety functions can be implemented by means of external switching devices.

Note:

Shield plates and shield connection kits are available. These can be used in the wiring installation for the Control Units and Power Modules to ensure that it complies with EMC guidelines.
