A1: The module has an IP65 protection grade, making it highly dust-proof and waterproof for outdoor installations.
A2: It supports four installation methods: wall hanging, holding pole, steel belt holding pole, and landing installation.
A3: The unit relies on a natural cooling design, which dissipates heat through direct contact at the bottom of the metal shell.
A4: It includes input over-voltage protection, output short-circuit protection, over-current protection, over-temperature protection, and D-level lightning protection.
A5: It operates reliably within a temperature range of -40°C to +55°C, with the ability to boot normally at -40°C.
A6: The input voltage range is 127-400VDC / 90-290VAC, which ensures a stable and normal output within this range.
