COTEK SP Series Pure Sine Wave Inverters

COTEK’s SP Series pure sine wave inverters provide low-distortion AC output suitable for sensitive loads such as computers, communication equipment, medical devices, and precision electronics. The series includes SP-1000, SP-1500, SP-2000, SP-3000, and SP-4000 models, supporting 12VDC, 24VDC, and 48VDC input configurations with selectable AC output voltages and frequencies via DIP switches. High conversion efficiency, typically exceeding 90%, helps reduce heat generation and maximize battery runtime.

Designed for reliability in harsh environments, the SP Series features fully isolated input and output, temperature- and load-controlled cooling fans, and comprehensive protections including reverse polarity, under-voltage, over-voltage, overload, short circuit, and over-temperature protection. Additional features include remote ON/OFF control, optional remote controllers, dry contact terminals for status monitoring, and power-saving modes for low-load operation. With certifications including UL, CE, FCC, and E-mark (model dependent), the SP Series is well suited for applications such as vehicles, marine systems, off-grid solar installations, portable power equipment, and industrial power solutions.
