NU33 100-600KVA K-Series

All units adopt modular design, these include power module, bypass module, monitor module, power distribution module (Only for single cabinet). Power module, bypass module, monitor module, centralized module are hot swappable. Wide input voltage range, line voltage range is 138-485V (phase voltage 80-280V), UPS should derate when input voltage is below 305V. Inside of the cabinet, there are multiple and redundant communication bus to control the system, if one communication bus fails, it will not affect the running of system. Remove one of the power modules, control or monitor modules will not affect the single running UPS or parallel running UPS.
High input power factor, it is up to 0.99. Three level topology design, efficiency is up to 96%. THDi<3% (100% non-linear load), THDi<5% (50% non-linear load) Dormancy   mode can be set, when load rate is very low, some power modules don’t work and transfer to dormancy mode, and the power module in dormancy mode will replace the working module regularly, in this way, it can balance the running time of the power modules and extend the lifetime of UPS. Support parallel expanded operation: maximum is 6 units (YMK3300-800/1000, maximum is 4 units). Support sharing batteries for the UPS in parallel.
Batteries number of each group can be selected from 30 pieces to 50 pieces, Large charging current can meet the requirement of longtime backup,3 intelligent charging methods.
Output power factor is 1.0, UPS can supply power to 100% unbalance load, High adaptability for load, it can connect full inductive load or capacitive load, 7 inches colorful touch screen is standard equipment, Support recording and exporting historic logs and fault logs, Support RS485, SNMP, dry contact card, support BMS, Support upgrade via USB.
