EVS Powers
1 / 5
Evs-00w is a high-power AC / DC (or DC / DC) power supply with a single output. Engineered with the latest circuit design, it features a compact structure and reliable performance.
The entire unit guarantees high stability precision and exceptional output efficiency. It offers a wide range of input voltages, built-in input over-voltage protection, output short-circuit protection, over-current protection, and over-temperature protection.
For thermal management, the cooling system utilizes natural heat dissipation. The power supply is designed in strict compliance with safety regulations and meets all safety standards for information technology equipment.
Key Features: Equipped with D-level lightning protection, a dust-proof and waterproof design (IP65 rated), and direct contact heat dissipation at the bottom. The metal shell and cable connector are secured with anti-off screws. It supports four installation methods: wall hanging, holding pole, steel belt holding pole, and landing installation.
