Description

High Voltage 220V, 85 - 300Vac, 45? - 65Hz Emerson Telecom Power Supplies,? R48-1800A


R48-1800A system features

The rectifier module uses active power factor compensation technology, power factor value of 0.99.
? Wide AC input voltage of the normal operating range to 85V ~~ 300V.

? The rectifier module the comprehensive soft switch technology, rated up to 91% efficiency. The system efficiency up to 88%. Rectifier module ultra low radiation. Rectifier module is able to meet the advanced EMC design, CE, NEBS, YD/T983 domestic and international standard requirements. The rectifier conduction and radiation can reach Classl B requirements.

? Rectifier module safety design meets UL, CE, NEBS standards.

? Rectifier module hot swap technology, plug-and-play with no damage, replacement time less than 1min.

? Rectifier module output overvoltage hardware protection and output overvoltage software protection. Software overvoltage protection, there are two options: one-off pressure lock mode, secondary overvoltage locked mode.

? Perfect battery management. Low battery voltage protection function and load power to achieve temperature compensation, automatic voltage regulator, stepless current limit, the battery capacity is calculated online battery test function.

? Historical alarm records can record 200; 10 group battery test data can be recorded.

? Network design, multiple communication interface provides one RS232 interface, Modem, dry contact, flexible networking, remote monitoring, unattended.
