Power Guard 2000

This controller board is a versatile and essential PCB designed specifically for managing and controlling UPS (Uninterruptible Power Supply) systems. It is engineered to monitor both voltage and current, ensuring precise power regulation. The board enables the safe transfer of power to the inverter section when all operating conditions are optimal.

Key features include:

Voltage and Current Monitoring: Continuously measures input voltage and current to ensure safe operation.
Temperature Control and Safety Relays: Actively monitors temperature and controls safety relays to prevent potential hazards.
Smart Power Management: Automatically directs current to the inverter section when conditions are safe and takes appropriate actions in case of any faults.
Data Output: Provides detailed real-time metrics, such as input voltage, input current, input wattage, output voltage, output current, and output wattage, which are displayed on an I2C-connected LCD.
Peripheral Support: Includes connections for cooling fans and communication modules to enhance functionality and integration.
Open Source Design: Fully open-source, making it easy for developers to customize and integrate into UPS projects with enhanced safety features.

This PCB significantly simplifies the process of building a reliable and efficient UPS system, combining advanced monitoring, control, and safety mechanisms into a single, user-friendly solution.
