Performance features

Ø  Have DC/DC insulating boosterfunction

Ø  Output voltage suspended from the ground

Ø  LCD+LED display -新葡京官方网址271111

Ø  -澳门新葡京娱乐50522.com-0805o.comAdjustable output voltage based on transmissiondistance and the load, continuous adjustment at between 210V and 400V

Ø  Input over voltage and under voltageauto protection function, with a protection time of no more than 20ms; afterfault clearance, automatically restore power supply

Ø  Output over voltage protection function,with a protection time of no more than 20ms; after fault clearance,automatically restore power supply

Ø  Output over voltage protection function,with a protection time of no more than 20ms; after fault clearance,automatically restore power supply

Ø  Open circuit protection: transmissionreturn circuit (positive or negative) is partially or completely destroyed, thesystem will cut off high voltage output at local side, with a protection timeof no more than 20ms; after fault clearance, automatically restore power supply

Ø  Short circuit protection: in case ofshort circuit of positive and negative, the system will cut off high voltageoutput at local side, with a protection time of more than 20ms; after faultclearance, automatically restore power supply

Ø  Electrical leakage protection: Outputover voltage protection function for no more than 20ms; after fault clearance,automatically restore power supply

Ø  Heavy current invasion connectionprotection: when the system detects the connection of mains supply and remotetransmission line, it will cut off high voltage output of local side, with aprotection time of no more than 20ms; after fault clearance, automaticallyrestore power supply

Ø  Fault insulation: various main modulesof single box or the complete system paralleled by poly boxes have faultinsulation function. In case of failure in one of the modules or box equipment,automatically quit running system, without influencing the normal operation ofother equipment

Ø  -澳门新葡京集团774220KA Lightning protection:have lightning protection and anti-surge function for output end, lightningprotection of no less than 20 KA

Ø  Fan fault alarm: in case of fan fault ofcertain rectifier module, system will shut down the output to the correspondentmodule; such module light on, and LCD shows fan fault of the correspondentmodule

Ø  Alarm: in case system protection, haveacoustic and light alarm and check the protection condition and alarming timeat LCD

Redundancy:dominant power is made of multiple power module, with N+1 redundancy design,with hot plug and current sharing function
