Siemens Digital Industry Brake Resistor JJY:023422620001 Manufacturer: Siemens Digital Industry Description: Brake resistor 25.00 Ohm, Type: JJY:023422620001 Type of accessory/replacement part: Brake resistor. Additional details: Brake resistor for power modules PM240-2 FSD P_MAX=22kW/12S/5% ED R=25 Ohm P_CONTINUOUS=1100W accessory for frequency converters. Brake resistor for the Power Module PM240-2 for the modular frequency converter SINAMICS G120. The brake resistors dissipate excess energy from the DC link. They are designed for use with Power Modules PM240-2 and PM240 (mounted next to the Power Modules), which have an integrated brake chopper and cannot feed generator energy back into the grid. For regenerative operation, such as decelerating a flywheel with a large moment of inertia, a brake resistor must be connected to convert the generated energy into heat. For Power Modules sizes FSD to FSGX, the brake resistors should be placed outside the control cabinet or outside the switchgear room to dissipate the generated waste heat away from the Power Modules. This reduces the cooling effort. Each brake resistor is equipped with a temperature switch. To avoid subsequent damage in the event of thermal overload of the brake resistor, the temperature switch should be monitored. The brake resistor is available for sizes FSA to FSC as well as for the Power Module PM240-2 (size FSC to FSF). For size FSGX, a pluggable braking module is optionally available.
