Introductions: The series is a uninterruptible power supply system that is an advanced on-line sine wave, with a maintenance bypass switch, with parallel redundant function, which can provide precision equipment with reliable and superior AC power supply. It applys to computer equipment, communication systems and industrial automation devices, etc. Because of its on-line design, unlike the backup-type UPS, its input voltage is constantly adjusted, filtering. When the mains supply is interrupted, it can supply uninterrupted power supply from emergency battery. In the case of overload or inverter failure, UPS will switch to bypass automatically, which is supplied by mains system. If the overload condition is removed, UPS will automatically switch back to inverter power supply status. Features: 1. All Digital Design 2. With reverse detection of AC zero line and positive line 3. Green environment protection type 4. With DC cool-start function 5. With battery input under-voltage, high-voltage alarm, protection function 6. Design for human-operation 7. With communication and minitoring function 8. Strong protection function (output hight-low voltage protection, output short-circuit protection, overload protection, over-temperature protection) 9. With fans to control Technical Parameter: Technical DataADA-10K ADA-10KS ADA-3C10K Rated output capacity 10KVA/8KW AC Input Rated Voltage 220Vac 380VAC Rated Frequency 50Hz Voltage Range 120 275VAC±5 Frequency Range （45 55）±0.5Hz Voltage of Bypass 80VAC×(1±5%)～285VAC×(1±5%) Battery Input Battery Pack Voltage 192VDC Battery Capacity×Quantity 12VDC×16 AC Output Voltage 220Vac±3% (inverter output) Frequency 46-54Hzz （AC input is normal） 50Hz±1% (AC input is abnormal) Dynamic Voltage Transients <5% Dynamic Transient Recovery Time < 60ms Wave Sine wave THD <3% (linear load) Sine wave THD <8% (non-linear load) Power Factor 0.8 Overload Ability 105-125% the switch to bypass after 1 minute Communication and Monitoring RS232 (can be transferred to 485), Stem node, Smart slot (can extend SNMP, SMS and other monitoring methods) Protection DC input over-voltage, under-voltage, overload, over-temperature, short-circuit, output over-voltage, under-voltage Transmission Meet the standard of YD/T983-1998 A Radiation Meet the standard of YD/T983-1998 A Conducted Immunity Meet the standard of YD/T983-1998 A Insulation Resistance > 2MΩ（500VDC） Insulation Strength 2121VDC （AC Input to ground, AC Output to ground, DC Input to DC Output）, no flashover in 1mins Working Environment Temperature －10 +40 Humidity 0 95%, Non-condensing Altitude ≤1500m, meet the derating requirements of GB3859.2-93 Storage Environment Inverter Temperature -40 +65 Humidity 0% 95%，Non-condensing Dimension (W×D×H) (mm) Towertype 248×620×500 248×460×500 248×460×500 Rack-mounted 432×500×192 Weight (Kg) Towertype 67.5 20 27 Rack-mounted 22
