Notes:
1. Optional configuration: Temperature sensor and its cables, battery rack and battery cables
2. Controller automatic power-off: If a battery low voltage disconnection (BLVD) occurs, the controller will fully disconnect from the
battery. At this moment, the controller is power-off, communication is failure, and the dry contact alarm is invalid. This control mode
can effectively protect the battery against overdischarge due to BLVD.
3. Weight: Packaging included, rectifier and controller excluded
1.2 Features
 The rectifier uses the active Power Factor Compensation (PFC) technology, raising the power factor to 0.99.
 Wide AC input voltage range: 85Vac ~ 300Vac.
 The rectifier uses soft switching technology, efficiency up to 96%.
 Ultra-low radiation. With advanced EMC design, the rectifier meets international standards such as CE, NEBS
and YD/T983 standards. Both the conducted and radiated interference in an optimal state can reach Class B.
 The design of rectifier safety 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.
 Improved 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.
 M221S and M222S support historical alarm record up to 200 pcs and historical record up to 1000 pcs. And
M820B/M830B supports historical alarm record up to 3000 pcs and historical record up to 60000 pcs.
 10 sets of battery test data records.
 Network design: Providing multiple communication ports (such as RS232, Modem, Ethernet and dry contacts),
which enables flexible networking and remote monitoring. M820B/M830B support the USB communication
interface.
 Improved lightning protection at AC side and DC side.
 Complete fault protection and fault alarm functions.
 NetSure 531 A41-S1 and NetSure 531 A41-S2 adopt the control mode of “Controller automatic power-off”, This
way effectively prevents the storage battery from deeply discharging after system battery protection drops out
and hence prevents the unattended outdoors and indoors server rooms from the damage due to the deep
discharge.
