reliability and quality control SMTPCB patch technology delivers a product qualification rate, contributing to dependable performance in the field. Stable, longlasting operation The program algorithm is designed to optimize the fan and photovoltaic panel battery system for maximum stability and longevity. Consistent power for loads Load output features a stabilized voltage, so the device maintains rated power even when battery feed conditions vary. Robust protection and durability The shell is well sealed, and the internal PCB is coated with three antipaint layers, providing moistureproof, dustproof, and antistatic protection. Use scenarios Outdoor solarpowered ventilation Ideal for remote or outdoor equipment where a fan is powered by a solar panel and battery, requiring reliable cooling with stable voltage. Offgrid power applications Suitable for installations where a solar charge source powers a load that must receive a steady voltage, such as sensor nodes, lighting, or small appliances. Harsh environment deployments Designed for environments with moisture, dust, or static exposure, ensuring continued performance in agricultural, industrial, or field research settings.
