Acrel ARD2F Motor Protection Controller

Acrel's MOTOR PROTECTION CONTROLLER, model ARD2F, is a powerful device designed for motor control and protection. It features support for two power modules, AC 220V power module (AC85-265V/DC100-300V) default, AC 380V power module (AC/DC100-415V) optional, and rated operating currents of 0.1A-5000A. With 10 channels of passive dry contacts, MODBUS RTU communication, and PROFIBUS_DP communication, the ARD2F is the perfect solution for reliable motor protection. Additionally, it has an IP20 main body and an IP54 display module for added durability.
