The 48V 20A model charger operates from mains AC 200-260V as input, supplying up to 20A charging output suitable for nominal 48V LiFePO4 battery banks. The charger's built-in protection technology provides protection against Over Voltage and Over Current output, Short Circuit and Reverse Polarity making it very safe to use.

Designed for LiFePO4 batteries

Achieve 100% SOC

Built-in protection system

Fast charging

Built in Protection System

AMPTRON® Lithium Iron Phosphate (LiFePO4) battery chargers have a built-in Protection System to prevent damage to the charger from almost any external accidental occurrence that would normally cause damage. The internal Protection System will automatically disconnect to prevent damage to the charger, and will automatically reconnect when the error condition has been resolved.

Protection System Features:
  • Over Voltage Protection - When the charger output voltage exceeds the maximum charging voltage, the charger enters a standby state. It will restore to normal working conditions automatically after troubleshooting.
  • Over Current Protection - When the charger output current exceeds the maximum charging current, the charger enters a standby state. It will restore to normal working conditions automatically after troubleshooting.
  • Short Circuit Protection - When the charger detects a short circuit at output terminals, the charger enters a short-circuit protection state. It will restore to normal working conditions automatically after troubleshooting. 
  • Reverse Polarity Protection - When the charger detects that the polarity at the output terminals are reversed, the charger enters a reverse polarity protection state. It will restore to normal working conditions automatically after troubleshooting.
This Protection System is designed to last throughout the life of the charger and provide reliable charging for thousands of cycles.
