R48-1800A network Refurbished Equipment
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.
