Advanced DSP Control DC Telecom Power Supply With 48V / 900W Rectifier Module
Description:
The innovative design of this module makes of it a highly efficient, reliable and cost effective solution for our customers.Due to the compact design and the small size 48V/900W rectifier module is suitable for any operation environment with low cost.
Application:
The 48V/900W rectifier module is specially designed for micro/pico wireless coverage, it's highly reliable and cost-effective for giant number sites.
For small power network access, the rectifier module adopts to indoor/outdoor harsh environment, high reliability, low maintenance cost.
- SELF PROTECTION AND RELIABILITY
DSP control with advanced software ensures the overall functions to meet almost all requirements from customers.
The module has a high reliability protection functions: basic functions as output/input protection, over / low input voltage , over/low output voltage protection, over temperature protection as well as high level protection functions as low voltage derating , High temperature derating,fan temperature- control and speed regulation etc.
- HOT-PLUG AND EASY MAINTENANCE
The monitor will automatically recognized the new plugged module and establish communication, communication between modules via RS485 for load sharing even when the monitor is in default phase.
Fixed by captive screws , small size, light, easy to maintain
