The Cotek SR1000 Pure Sine Wave Inverter is engineered to provide uninterrupted power to critical systems, making it an ideal choice for telecommunications, data centers, industrial control systems, and other applications where power quality is paramount. Its pure sine wave output ensures that even the most sensitive equipment operates smoothly, without the risk of damage or interference commonly associated with modified sine wave inverters.

Designed with versatility in mind, the SR1000 offers selectable on-line and off-line modes, allowing users to tailor the inverter's operation to their specific needs. The built-in AC transfer switch ensures a rapid and seamless transition between AC input power and inverter power, maintaining continuous operation of connected devices during power interruptions.

The user-friendly LCD module provides clear and concise information, enabling users to monitor system performance at a glance. Additionally, the inverter's RS-232 communication port facilitates remote management and control, making it easy to integrate into existing monitoring systems.

Safety is a top priority with the SR1000. The inverter is equipped with comprehensive protection features, including input over-voltage and under-voltage protection, reverse polarity protection via internal fuses, output short circuit and overload protection, and over-temperature shutdown to prevent overheating. These safeguards work together to protect both the inverter and connected equipment from potential damage.

The SR1000's robust design is complemented by its efficient cooling system, which includes temperature-controlled fans that adjust their speed based on the inverter's operating temperature and load conditions. This intelligent cooling mechanism helps maintain optimal performance while minimizing noise and extending the lifespan of the inverter.

For added convenience, the inverter features dry contact terminals for system alarms, allowing integration with external alarm systems to provide immediate notification of any fault conditions. The inclusion of both hard-wire and dual AC outlet output connections offers flexibility in how the inverter is deployed within various setups.
