Comprehensive protection: antireverse connection, undervoltage, overvoltage, overpower, overtemperature, and overcurrent safeguards protect the system and battery bank from fault conditions, reducing the risk of damage and downtime. Efficient heat dissipation: a thickened heatsink and two way ventilation enable effective heat removal during continuous operation. Intelligent fan control: smart temperature and current based fan control starts and stops automatically to balance cooling and noise. Accurate LCD display: clear readout of input voltage, output voltage, temperature, current, power, and capacity for quick status checks. Robust and compatible design: suitable for common DC power setups including solar charge controllers, battery inverters, and portable power stations; compact footprint with sturdy construction. Clear value: provides integrated protection, cooling, and monitoring in a single module to help extend system life and uptime. Use scenarios Off grid solar systems with battery banks needing safe charging, monitoring, and protection. UPS or edge data equipment requiring real time status and fault protection. RV, marine, or remote sites where space is limited and loads vary.
