A microprocessor-based automatic transfer controller designed for medium and low-voltage power systems. It integrates programmable control, current measurement, voltage-sensing wire-break detection, sequential load switching, intelligent load shedding, an LCD display, and Modbus RTU communication over RS485.<\/p>\n

The module accurately monitors the three-phase voltages of both incoming power supplies. It detects overvoltage, over\/undervoltage, over\/underfrequency, phase loss and reverse phase sequence, and provides volt-free contact outputs for switch control. It supports both open and closed-transition transfer, with a closed-transition overlap time of less than 100 ms.<\/p>\n

Enhanced source sensing.<\/strong> Measures three-phase voltage and current from both incoming sources.<\/p>\n

Coordinated switching.<\/strong> Supports sequential load switching and intelligent load shedding \u2014 disconnecting non-critical loads to ensure uninterrupted power supply to critical loads.<\/p>\n

Configured transfer.<\/strong> Transfer inhibit, open or closed transition, and selectable auto\/manual restoration support site-specific operation.<\/p>\n

Event traceability.<\/strong> Stores up to 200 timestamped event records (actuation, operation, warning, fault event) for switching review and fault analysis.<\/p>\n

Local and remote operation.<\/strong> 4.3-inch LCD, front-panel controls and Modbus RTU communication support operation and maintenance.<\/p>\n

Naming system.<\/strong> SQIC \u2013 3000 \u2013 S \u2013 CM: 3000 = to control 3 breakers (2000 = to control 2 breakers); S = synch. transfer, close transition; O = open transition; CM = current measurement (blank = without current measurement). Product type: SeQuence Intelligent Controller (SQIC).<\/p>\n
