Factory Making High Quality Original Rectifier/DC Power Supply

Product introduction:
Advanced modular designed mini system, can provide sufficient power to meet the requirements of the communication system. Rack-mounted, suitable for all kinds of exchange room, Server room, base stations, satellite communications, data communications, locomotives and utility power system etc.

Features:
•Circuit of the Rectifier modules have two parts, one is PFC adjust; the other is DC/DC transfomialion.AII technology make the wide input voltage range (8SV-290V).
•High efficiency rectifier modules used soft switch technology, while load rate10% then efficiency can be 91 %, 50% load rate the efficiency can be above 96%
•With step less current limiter technology, output current is continuously adjustable.
•Adopted step less temperature control speed, it can reduce power consumption and prolong the life of the fan.
•Sharing Load, Equalized-current imbalance 3%
•Optional Ethernet Interface through SNMP and TCP/IP
•Controller MCU
•Digital signal collection via internal RS485 bus; RS232 interface for remote operation
•Hot-swappable technology, plug and play, N +1 redundancy, extension slots.
•2U height, light weight, High power density.

Monitoring module :
Monitoring module monitors the working status of each rectifier module, has functions of collecting, displaying and setting the operation parameters of the system. It can also communicate with an external computer and form a local or remote centralized monitoring system.

Distribution unit:
•Shunt load with short-circuit and over current protection, shunt capacity can be adjusted according to user requirements:
•Battery Input should connect with an external fuse protector.
•Power off auto/manual, load off on/off control switch, etc;
•Battery current, the total load current can be detected;
•All DC outputs have fault detection function;
•LVDS2 function to protect load and battery;
•Capacity of MCB in each channel is 50A
Communication protocol:
•Safe operation: With the host computer own password and dual authentication, greatly protect system parameters safely.
•Parameter setting Is comprehensive, detailed: &lave module time setting, temperature compensation setting, output over/low voltage setting, boost charge time setting, over-voltage and recovery voltage setting, boost charge setting.
