Product Overview:

The COTEK SD1500 stands out with its pure sine wave output, ensuring that sensitive electronics receive clean and stable power, free from the distortions often associated with modified sine wave inverters. This feature is crucial for preventing potential damage to devices such as medical equipment, audio/video systems, and other sensitive electronics.

One of the standout features of the SD1500 is its parallel redundancy design. This allows users to connect multiple inverters in parallel, effectively expanding the power capacity to meet higher demands. This scalability ensures that as your power requirements grow, your inverter system can adapt accordingly without the need for a complete overhaul.

The built-in Automatic Transfer Switch (ATS) and AC circuit breaker enhance the inverter's functionality by allowing automatic switching between different power sources, such as battery and grid power. This ensures a continuous power supply, which is essential in applications where uptime is critical.

Flexibility is further emphasized with selectable output voltage and frequency settings. Users can adjust these parameters to match specific application needs, making the SD1500 suitable for a diverse range of environments and equipment requirements.

Safety has been a paramount consideration in the design of the SD1500. The inverter is equipped with comprehensive protection features, including safeguards against reverse polarity, under and over-voltage conditions, short circuits, overloads, and overheating. These protections not only ensure the longevity of the inverter but also protect connected devices from potential damage.

For users seeking advanced monitoring and control capabilities, the RS-232 communication interface provides a convenient solution. This feature allows for seamless integration with external systems, enabling real-time monitoring and adjustments to optimize performance.

The SD1500 is available in various models to accommodate different input voltage requirements, including 12V, 24V, and 48V DC inputs. This variety ensures compatibility with a wide range of power systems, from small-scale setups to more extensive installations.
