Reliable DC Telecom Power Supply Of High Efficiency 2000W 48V
The innovative design makes great customer advantages of high
efficiency, reliable and cost-effective.
■ APPLICATIONS
● BTS, FIBER AND SWITCH TELECOM
Telecommunication carriers consume more and more energy, reducing
the power consumption is carriers’ overwhelming society duty, and
they have to cut TCO by power saving to face competition.
Medium efficiency and high efficiency modules are mixable to
maximize cost-saving and power system efficiency.
● NETWORK ACCESS
For medium and small power network access, because of giant
numbers, the cost-effective and higher efficiency module are key
components of power supply operation in indoor/outdoor harsh
environment with high reliability.
● DATA CENTER, POWERS SERVER AND COMPUTER
The high efficiency module is also designed for data center to
replace UPS power, comparing with UPS’s born disadvantage---low
efficiency, low reliability, high maintenance cost, the high
efficiency module suits for data center excellently.
● ELF PROTECTION AND RELIABILITY
DSP control with advanced software ensures the overall functions to
meet almost all requirements from customers.
The basic protection of input/output fuse, and input/output low
voltage/over voltage protection, also high level protection of
power de-rated when input low voltage and high temperature, and
temperature regulated fan speed, all these functions create high
reliability.
Hot-plug and easy maintenance
The monitor will automatically recognize new plug module and
communicate, and communication between modules via RS485 for load
sharing even when the monitor is fault.
The module is spring screw locked with its light weight and small
dimension, zero setting, the module replacement is non-tool and
very easy, the low technology worker is certificated.
