Siemens G120 Variable Frequency Drive Power Unit, Siemens G120 Variable Frequency Drive, Siemens G120, the new PM240-2 power module utilizes a new hardware platform. This enables increased power density and the use of a new cooling solution (through-the-wall technology); this is particularly true for high requirements in control cabinet cooling. Additionally, the PM240-2 power module is suitable for type applications. When combined with a fail-safe control unit, it can achieve a Safety Integrated drive solution. The PM240-2 power module is available for products with seat numbers FSA to FSF, with or without an A-grade integrated input filter (small filter, suitable for 200 V and 400 V line voltages). The power module with an integrated A-grade input filter is suitable for connection to a TN power supply system. Power modules without an integrated input filter can be connected to a grounded TN/TT power supply system or an ungrounded IT power supply system. There are limitations on the length of large cables between the variable frequency drive and the motor. If cables longer than the limit are required, output reactors can be connected. Siemens G120 Variable Frequency Drive Power Unit, Siemens G120 Variable Frequency Drive, Siemens G120Through-the-wall installation typeThrough-the-wall products allow the heat sink of the power module to pass through the rear panel of the control cabinet. Applications that reduce the heat generation inside the control cabinet to a minimum should use through-the-wall products. Shielding panels and shielding connection kits can be used. When installing the control unit and power module wiring, these products can be utilized to ensure compliance with EMC standards. For more information on shielding connection kits and shielding panels for control units and power modules, please refer to...Power Module PM240, equipped with a braking chopper (for four-quadrant applications), is suitable for numerous applications in the general mechanical manufacturing field. For power modules with the base number FSGX, an optional plug-in braking module can be ordered. There is a limit on the length of the large cable between the variable frequency drive and the motor (regarding the allowable large cable length. If cables longer than the limit are required, an output reactor can be connected. Additionally, an input reactor can also be ordered, which will reduce power line harmonics and voltage/current spikes. The Power Module PM240 is suitable for integrated applications. When combined with a failsafe control unit, it enables a Safety Integrated drive solution. The Power Module PM240 with a base number of FSGX (i.e., power above 160 kW) is only suitable for basic functions (STO, SS1, and SBC).
Power modules without integrated input line filters can be connected to a grounded TN/TT power supply system or to an ungrounded IT power supply system.
The PM250 power module is suitable for a wide range of applications in general mechanical engineering. This module can directly回馈 braking energy back to the power supply system (quadrant applications, no need for a braking chopper).
The power module PM250 incorporates the globally recognized Efficient Infeed Technology. This design endows the module with regenerative capability, allowing it to return energy generated during electrical braking to the power supply system rather than dissipating it as heat in a braking resistor. This not only saves space in the switchgear but also eliminates the need for selecting braking resistors and wiring. Moreover, it reduces the heat generated within the switchgear.
The PM250 power module offers both specifications with an integrated A-grade input filter and specifications without the integrated component. For the PM250 power module with an integrated A-grade filter and an FSC form factor, to achieve B-grade immunity, a B-grade filter option must be installed at the bottom. Additionally, the PM250 power module is suitable for integrated applications. When combined with a fail-safe control unit, it can achieve a Safety Integrated drive solution. The PM250 power module with an integrated A-grade input filter is suitable for connection to a TN power supply system.
In summary, power modules without integrated line filters can be connected to a grounded TN/TT power supply system, or to an ungrounded IT power supply system.
