4. Delivers a maximum output of 36V and 3.5A per channel; offers robust driving capability compatible with a wide range of light source board specifications.
5. Supports remote firmware upgrades, enabling feature updates and bug fixes without the need for on-site visits or device disassembly.
6. Features an RS-485 communication interface and supports the Modbus fieldbus protocol.
Introduction
This grow light controller is designed to drive LED grow light panels. It integrates six-channel constant-current driving, brightness adjustment, four-channel temperature monitoring, fan cooling control, RS-485 communication, and remote firmware upgrade capabilities. It can simultaneously drive six channels of LED light panels with different wavelengths and enables stepless light intensity adjustment by varying the drive current. Equipped with a standard RS-485 interface and supporting the Modbus fieldbus protocol, the controller allows for functions such as light switching, fan speed control, and temperature reading via Modbus commands. It also supports remote online firmware upgrades, enabling feature updates and bug fixes without the need for disassembly or on-site visits. This highly integrated, remotely manageable driver-controller is designed for smart plant lighting systems and is primarily used in applications requiring controlled lighting, such as plant factories, vertical farming, greenhouse supplemental lighting, tissue culture, and life science experiments.
