Overview
The ABB ACS355-03U-38A0-4+J402+J404+N827 is a compact, cabinet-mounted industrial variable frequency drive (VFD) designed for precise machinery control and solar pump applications. Rated at 20 HP (15 kW) with a 38 A output current, this 3-phase drive operates efficiently within a 380–480VAC input range, delivering stable power delivery for industrial and renewable energy systems. The drive features a basic operator panel with a speed potentiometer, start/stop pushbuttons, and forward/reverse switches for intuitive local control. With IP20 protection and a robust R4 frame, it meets UL TYPE OPEN standards for open-type installations in indoor environments. Weighing just 9.7 lbs (4.4 kg) and measuring 9.61" x 10.24" x 6.65" (244 x 260 x 169 mm), the ACS355 is ideal for space-constrained control panels and enclosures. Its 3-phase input and output ensure balanced power distribution, while the compact design simplifies integration into existing motor control systems. Manufactured by ABB, a global leader in low-voltage drives, this drive combines proven reliability with energy-efficient operation for demanding applications including pumps, fans, conveyors, and solar water pumping systems. The drive supports standard motor control protocols and is compatible with ABB’s extensive ecosystem of accessories and software tools.

FENA-21
The FENA 21 DualPort module supports Three protocols Modbus-TCP, EtherNet/IP, and the PROFInet IO RT network. The Modbus-TCP protocol is simply the Modbus protocol used on top of Ethernet-TCP/IP. Modbus-TCP is an open Industrial Ethernet network which has been specified by the Modbus-IDA User Organization. EtherNet/IP is based on the Common Industrial Protocol (CIP), which is also the framework for both the ControlNet and DeviceNet network protocols. PROFInet IO RT is an open network based on the PI Organization standard.
