SL Series High-Power Inverter/Chargers by COTEK

COTEK’s SL Series inverter/chargers are available in 2000W and 3000W models and feature a pure sine wave output suitable for sensitive electronics and critical loads. Each unit integrates an inverter, high-current battery charger, and a 50A rated bypass switch, allowing seamless operation in parallel with grid AC power. The SL Series supports power sharing, intelligent load management, and fast AC transfer, making it well suited for backup and hybrid power systems.

Equipped with a self-diagnostic microprocessor, the SL Series continuously monitors system status and displays fault conditions through visual and audible alarms. Advanced charging capabilities include four-stage battery charging consisting of bulk, absorption, float, and equalize modes with battery temperature compensation and optional remote configuration. Additional features include local and remote control, RS-232 communication, dry contact terminals, and loading- and temperature-controlled cooling. Comprehensive protection functions include DC input over- and under-voltage protection, AC input and output fault protection, short circuit protection, overload protection, and over-temperature protection, ensuring reliable operation in harsh environments. Certified to UL458, UL1741, and FCC standards, the SL Series is ideal for industrial backup power, mobile power systems, telecom, and off-grid energy applications.
