This product is a general Poe separator for network camerasIt has the characteristics of small size, high efficiency, stable operation and long transmission distance. It has overload protection, output short-circuit protection and other functions.
Product Description:
1. Dv-pd-1210 is an IEEE802 compliant3af standard, 28*82mm size, line length 205mmHigh performance Poe products with photoelectric isolation. The output power is to meet the power consumption demand of more than 90% of the camera in the market.
2. Adopt sd4952b chip, with standard isolation transformer 38~57v, and a variety of protection circuits!
3. Poe protocol: ieee8023af
4. Compatible with non-standard 48V power supply (only through 45+, 78 -)
5. Poe power: 13.5w (12v/1.1a)
6. Isolation voltage: 1500V
7. Poe transmission: (1, 2) + / (3, 6) - and (4, 5) + / (7, 8) - adaptive
8. Crystal head output: data (1, 2) + / (3, 6), positive power supply (4, 5) negative power supply (7, 8).
