概述
PM240-2动力模块的制动电阻，框架尺寸FSD
DC链路中的多余能量在制动电阻中消散。
The braking resistors are intended for use with PM240-2 Power
模块，具有集成制动斩波器，但可以 -
对供应系统没有再生能量。用于再生
operation, e.g. the braking of a rotating mass with high moment
of inertia, a braking resistor must be connected to convert the re-
sulting energy into heat.
制动电阻可以横向安装在旁边
PM240-2 Power Modules. The braking resistors for the Power
模块，Frame Size FSD到FSF，应放在外面
control cabinet or outside the switchgear room so that the heat
is dissipated away from the Power Modules. The level of air con-
ditioning required is therefore reduced.
Every braking resistor has a temperature switch (UL-listed). The
应评估温度开关以防止后果 -
tial damage if the braking resistor overheats.
