Product Overview

The COTEK SD3500 is engineered to deliver a high-quality pure sine wave output with a THD of less than 3%, ensuring compatibility with all sensitive electronic devices. Unlike modified sine wave inverters, the SD3500 guarantees stable and interference-free power, making it ideal for medical equipment, industrial tools, and telecom systems.

One of the standout features of this inverter is its parallel redundancy capability. By connecting multiple SD3500 units, users can expand total power capacity up to 17.5KW, providing a scalable solution for high-power applications.

The built-in Automatic Transfer Switch (ATS) seamlessly transitions between the inverter and an external AC power source, ensuring continuous operation in mission-critical environments. The inverter also features an integrated AC circuit breaker, enhancing protection against unexpected power fluctuations.

Users have the flexibility to select from two output voltages—115V or 230V AC, making the SD3500 adaptable for various regional power standards. Additionally, the 50Hz/60Hz frequency selection allows for deployment across different applications worldwide.

To further enhance reliability, the SD3500 is equipped with comprehensive protection mechanisms, including reverse polarity protection, under/over-voltage protection, short-circuit protection, overload protection, and overheating protection. These features ensure the safety and longevity of both the inverter and connected devices.

For professional applications requiring remote monitoring, the SD3500 is equipped with an RS-232 communication interface, enabling users to monitor and control the inverter from a remote location. This functionality is particularly useful for telecom, industrial, and off-grid solar power systems.
