Cotek Pure Sine Wave Charger-Converter Combos

1. Pure Sine Wave Inverter:

   • High-Quality Current Conversion: The integrated inverter produces a pure sine wave, similar to that of domestic power grids, enabling safe powering of sensitive devices such as computers, electronics, refrigerators, and other household appliances.
   • Protection for Sensitive Devices: Unlike modified sine wave inverters, pure sine waves prevent potential damage to sensitive electrical devices.

2. Integrated Battery Charger:

   • Optimized Battery Charging: The built-in charger can efficiently recharge various types of batteries (lead-acid, AGM, lithium). It optimizes the charging process according to the battery type, extending their lifespan.
   • Multi-Stage Charging: Most Cotek chargers use a 3 or 4-stage charging strategy (Bulk, Absorption, Float, and sometimes Equalization) to ensure fast and complete recharging while protecting the battery from overcharging.
   • Network and Generator Compatibility: The charger can be powered by external sources such as shore power, a generator, or solar panels.

3. Automatic Transfer Function:

   • Automatic Switching Between Power Sources: The Cotek combo automatically switches between the external power source (shore, generator) and the inverter, ensuring your devices remain powered without interruption. This feature is crucial in marine and off-grid environments.

4. Energy Efficiency and Smart Management:

   • Smart Energy Management: Cotek combos are designed to optimize energy consumption, reducing losses and increasing the overall system efficiency. Some models are equipped with energy-saving functions or standby modes to reduce consumption when demand is low.
   • High Efficiency: These combos are designed to minimize energy loss during conversion, with an efficiency rating of up to 90% or more, depending on the model.

5. Robust and Reliable Design:

   • Durable Design: Cotek products are built to withstand tough environments such as marine or off-grid applications, where moisture, heat, and vibrations can affect performance.
   • Integrated Safety Features: Protection against overloading, overheating, short circuits, excessive discharge, and battery overcharging ensures safe operation and long lifespan.
