Active power filter
The active power filter is a rack LED type, with an LED on the front panel indicating the module status, installed in the cabinet, and used for centralized monitoring through the monitoring of the cabinet; According to the capacity of power modules, there are four models: 50A, 75A, 100A, and 150A. This manual only provides necessary information for user installation and use. If you need more detailed information, please consult the corresponding supplier. The specific selection table is as follows:
Model | Capacity | Size (W * D * H) | Weight |
APF-50A-4L | 50A | 350x465x88mm | 14kg |
APF-75A-4L | 75A | 500x523x160mm | 25kg |
APF-100A-4L | 100A | 500x578x200mm | 35kg |
APF-150A-4L | 150A | 500x603x220mm | 45kg |
connection terminal
The wiring terminals of the module are located at the rear of the module and are divided into power terminals, CT (current transformer) terminals, and communication terminals. Please refer to Figure 3-3 for details.
