500W Submersible Aquarium Heater with Intelligent Frequency Conversion, Over-Temp Protection, and Auto Off

The 500W Intelligent Variable Frequency Aquarium Heater is a submersible heating solution designed for freshwater and saltwater aquariums ranging from 52 to 80 gallons. It operates on 110-120V power and features a precise temperature control range of 68-93°F (17-34°C) with an accuracy of ±0.1°F, utilizing a PID controller for stable temperature maintenance. The heater incorporates intelligent frequency conversion technology that automatically reduces power consumption as the water approaches the set temperature, operating at minimal power to maintain the desired environment, which promotes energy efficiency. Safety features include automatic power-off and over-temperature protection; the system will stop heating and flash indicator lights if it detects a lack of water or exceeds safe temperature limits, protecting aquatic life. The heating element is constructed from an explosion-proof quartz glass tube with a nickel-chromium heating wire for rapid, efficient heat transfer and durability in both freshwater and marine conditions. The external protective shell is made from high-temperature resistant ABS material to prevent burns and is equipped with strong suction cups for secure mounting to the tank wall or bottom. The unit is intended to be fully submerged during operation.
