2. System Features
2.1 High Performance Index
◆ Latest HF Rectifier and PFC Technology. Input Power Factor 0.99, THDI≤3%, compatible with 208/220/230/240Vac,50/60Hz Grid
supply system. ◆ Wide Input Range from 110-300Vac in 100% load(When Load is below 50%, Input Lower Limit can lower than 110Vac)which can
reduce the battery usage and maximize battery life-time.
◆ Latest 3-Level-Inverter technology to meet the critical loads. Output PF=1, Overall efficiency up to 95% (98.5% under ECO mode)
◆ Powerful overload ability with output short circuit protection: 1-3 KVA: 120% overloads for 1 minute.150% for 60ms transfer to bypass
and alarm.
6-10KVA: Online mode: 102-110%:30 minutes; 110-130% :10 minutes; 130-150 %:30s; ≥150%:500ms
6-10KVA: Battery mode: 102-110% :10 minutes, 110-130% :1 minute; 130-150 %: 10s; ≥150% 500ms
◆ Can be connected with all kinds of generators to save customers costs.
◆ Intelligent charger system, charging current from1-12A adjustable, adopting constant charging, float charging and equalized charging
methods, which could meet various requirements from different Lithium-ion battery pack and greatly expand batteries’ life-time
◆ Powerful battery anti-reverse connected alarm and protection. When battery is unconnected, UPS will alarm with DC unconnected.
When the DC polarities reversely connected, UPS will not be turned on and shows DC failure, only when correcting polarities then UPS will
be back to work normally.
◆ Battery configuration: for 6-10kva, battery quantity could be transfer into 16/18/20pcs without changing any spares;
◆ Powerful battery test function, users can do or cancel the battery test on LCD screen directly.
◆ Intelligent Short Circuit Protection. When short circuit lasts less than 3s, UPS will restart to inverter mode automatically after short-circuit
removal. If the short circuit lasts over 3s, UPS will lock the inverter for protection.
◆ Remote EPO mode available.
◆ 2.4-inch Large Color Dot-matrix LCD+LED Screen with multi-functional keyboard to check UPS and lithium-ion system parameters, such
as work status, temperature control and fault histories, self-diagnosis periodically discharge settings, etc.;
◆ Battery Self-testing can be done on the LCD directly. Battery Capacity, UPS working mode (Online or ECO first) can be set on the
screen. All history faults and statistics can be seen on the screen to help user analyze the working summary of the UPS.
◆ Multi-page history record can be tracked on LCD highly improved the efficiency for site engineers to check the UPS and lithium-ion
battery running days and cumulative running status of UPS
◆ Intelligent Ventilation design greatly reduces noise.
◆ Standard 19” Rack-mount design, compared to traditional VRLA battery pack, BH-N UPS system can be compatible with standard
communication cabinet and greatly save spaces.
◆ Highly integrated PCBA board and wiring design makes the system convenient in maintenance and greatly saves service time.
