Analysis of AB frequency converter

The integrated PID controller can automatically adjust the output frequency and process variables

Three programmable jump frequency bands prevent the frequency converter from continuously operating at resonant frequencies and avoid mechanical damage

◆ Optional fan/pump curves provide voltage drop modes for centrifugal fan and pump loads

The sleep function of ◆ automatically shuts down the machine when the system demand drops to a predetermined standard; Automatically start the machine when system demand increases

◆ For some unmanned operating environments, when the system is powered off and then restored, the frequency converter will automatically restart and operate

◆ Specific inputs such as Freeze/Fire and Purge can be directly connected to emergency systems such as fire protection

RS485 communication integrated into the frequency converter

◆ The built-in Modbus RTU and Johnson Metasys N2 protocol are optional parameters, without the need for additional software and hardware support to drive the Serial Interface (DSI) communication module and accessories

◆ Using DriveExplorer and DriveTools can be easily used for programming, monitoring, and controlling frequency converters

◆ The complete set of frequency converters meets UL standards, enhancing installation flexibility and allowing the frequency converter to be directly installed in the switchgear

The complete set of frequency converter circuit breakers and contactor bypass equipment can be started by combining operator panels, controllers, communication, and pre assembled power options with simple assembly

◆ The complete set of inverter bypass contactors provides three pairs of contactor contacts. When the inverter is in bypass mode, it can test the function of the inverter and isolate the inverter

Installation of AB frequency converter

1. Clear labeling of terminal blocks and appropriate layout can directly wire power and control systems that require small wire bending degrees;

2. Compact panel assembly design, saving valuable panel space;

3 packaging options;

4. Integrated electromagnetic compatibility (EMC) solution, allowing out of the box features;
