1.3 Features

The rectifier uses the active Power Factor Compensation (PFC) technology, raising the power factor to 0.99

Wide AC input voltage range: 85V ~ 290V (NetSure 701 A51) or 85Vac ~ 300Vac (NetSure 501 A50 & NetSure

501 AA0)
The rectifier uses soft switching technology, raising the system efficiency to 89% (R48-1800)/ 90% (R48-3200)

Ultra-low radiation. With advanced EMC design, the rectifier meets international standards such as CE and

NEBS. Both the conducted and radiated interference reach Class B
The rectifier safety design complies with UL, CE and NEBS standards

High power density

Rectifiers are hot pluggable. It takes less than 1min to replace a rectifier

Two over-voltage protection methods are optional: hardware protection and software protection. The latter one

also has two optional modes: lock-out at the first over-voltage and lock-out at the second over-voltage
Perfect battery management: The management functions include the LLVD (optional), BLVD, temperature

compensation, auto voltage regulation, stepless current limiting, battery capacity calculation and on-line battery
test, etc
Up to 200 pieces of historical alarm records, and 10 sets of battery test data records

Network design: Providing multiple communication ports (such as RS232, modem, RJ45 and dry contacts),

which enables flexible networking and remote monitoring
Perfect lightning protection at AC side

Complete fault protection and fault alarm functions
