COTEK SPT Series Inverter with Transfer Switch

COTEK’s SPT Series pure sine wave inverters feature a built-in transfer switch and AC circuit breaker, allowing automatic and fast switching between inverter operation and utility or generator power. Available in 1200W, 2000W, and 3000W models, the SPT Series supports 12VDC and 24VDC battery systems and provides low-distortion AC output suitable for sensitive electronics and critical loads. High surge tolerance and efficiency levels up to 92% ensure dependable operation under demanding conditions.

Designed for intelligent system integration, the SPT Series supports MODBUS (RS-485) and RVC protocol communication, optional remote controllers, and dry contact terminals for system monitoring and control. Additional features include input and output isolation, MOSFET-based reverse polarity protection, selectable output voltage and frequency via DIP switches, and power-saving modes for reduced idle consumption. Comprehensive protection functions include over-voltage, under-voltage, overload, short circuit, over-temperature, and AC input fault protection, helping ensure long-term reliability. Certified to UL458 and applicable EMC standards depending on model, the SPT Series is well suited for mobile power systems, industrial backup power, telecom, marine, and off-grid energy applications.
