12-48V 4 Port POE Power Module, 4-Port PoE Ethernet Power Injector, Gigabit Ethernet PoE Ethernet Desktop Switch for IP Camera, Compatible with International Security Standards

Simple and comfortable: This non-standard passive PoE injector is a simple and practical device that is supplied via Ethernet cable for PoE or non-PoE devices. The PoE injector is compatible with IEEE802.3af / at network devices. 【Standard POE Power Supply Units】 Use IEEE802.3af / with standard POE power supply devices such as DAHUA, and other brands of IP cameras or use IEEE802.3af / 802.3at standard Poe splitter for non-POE devices. 【Does not have the automatic detection function】 It does not have the automatic detection function. After connecting the network device, the powered device, or the Poe Splitter, you will have to force direct power to the network device, and the power powered device must support the Poe-Pin 4/. 5 (+), 7/8 (-) medium span. Safe to use: Made of plastic, strong and durable. It complies with international standards for safety products and is safe to use. Storage temperature and humidity: -20 ~ +85 °C, 10 ~ 95% RH. Working temperature: 0 ~ + 40 °C. Operating humidity: 20~90% RF, no condensation Command: Select depending on the power consumption of your device. To ensure stable operation, the total power consumption must be lower than the total power supply. The supply voltage should not exceed 48 V DC.
