Introducing the COTEK CX1215 Advanced Battery Charger, a state-of-the-art solution designed to efficiently charge and maintain your batteries. With its advanced 3-stage charging process, universal AC input, and compatibility with various battery types, the CX1215 ensures optimal performance and longevity for your power systems.

Key Features:

• Universal AC Input with Active Power Factor Correction (PFC): Accepts a wide AC voltage range (90–264VAC) with active PFC, ensuring efficient energy consumption and compatibility with global power standards.
• 3-Stage Charging Capability (IUOU): Utilizes Bulk, Absorption, and Float stages to ensure batteries are charged safely and efficiently, enhancing battery life and performance.
• Compatibility with Multiple Battery Types: Designed to work seamlessly with Lead Acid, Li-ion, Gel, and AGM batteries, providing versatility across various applications.
• Built-in Battery Rescue Function: Automatically initiates a reconditioning process every 14 days to prevent battery fatigue and sulfation, maintaining optimal battery health.
• Support for Remote Controller CR-1 (Optional): Offers the convenience of remote monitoring and control, allowing users to manage the charging process from a distance.

Advanced 3-Stage Charging Process:

1. Bulk Stage (Constant Current): Begins by charging the battery at a constant current until it reaches the set charging voltage, rapidly restoring battery capacity.
2. Absorption Stage (Constant Voltage): Maintains the set voltage while reducing the charging current, ensuring the battery is fully charged without overcharging.
3. Float Stage: Keeps the battery at 100% charge by applying a lower voltage, allowing the charger to remain connected indefinitely without harming the battery.

Safety and Protection:

The CX1215 is equipped with multiple protection features to ensure safe operation:

• Short Circuit Protection: Reduces current to prevent damage in the event of a short circuit.
• Over Voltage Protection: Shuts down the output if the voltage exceeds safe levels, with automatic recovery after resetting AC power.
• Over Temperature Protection: Monitors internal temperatures and reduces output or shuts down if necessary to prevent overheating.

Additional Features:

• Voltage and Temperature Compensation: Adjusts charging parameters based on temperature variations to ensure optimal charging in diverse environments.
• 2-Stage Fan Speed Control (Sleep Mode): Dynamically adjusts fan speed based on load and temperature, reducing noise and energy consumption.
• Output Power OK and Alarm Signals: Provides status indicators and alerts for easy monitoring and troubleshooting.
