Mecer 2400VA, 1400W, 24V DC-AC Inverter (Modified Sine Wave) LCD Display Cables to connect the unit to a battery are included. A 220V power cable is included to recharge the battery while the power is on. May be used as an inverter (to power 220V devices such as TVs from a battery) or a UPS (runs the device from the standard 220V power while the battery charges) *EXTERNAL BATTERIES REQUIRED* MODEL: Mecer IVR-2400LBK CAPACITY: 2.4KVA/ 1440W Power Factor: 0.6 Intput voltage range: 90-280VAC LINE MODE Output voltage: Bypass mode: 0utput voltage same as input voltage AVR mode:Output voltage = Input voltage*1.2 @ Input voltage < 200VAC Output Frequency: Same as input BATTERY MODE Output voltage: 230Vac 10% Transfer Time: 20ms typical Waveform: Modified Sine-wave OVERLOAD CAPABILITY Bypass Mode (in VA and Watts): Load >110%15% , alarm 5 mins then fault Load >130% 15%, fault immediately. AVR Mode (in VA and Watts)@ Input voltage > 170VAC: Load >100%15%, go to bypass mode AVR Mode(in VA and Watts)@ Input voltage < 170VAC: Load >60%15%, go to bypass mode Battery Mode (in W): 1) Load>110% 15%, overload alarm for 15s, and then will switch to fault mode for 10s, Then unit will re-start

times. 2) Load>120% 15% , fault & cut off O/P immediately. SHORT CIRCUIT PROTECTION Line Mode: Breaker Battery Mode: Current limit +Firmware Protection BATTERY Battery Voltage: 24VDC Acceptable Battery Type: Rechargeable lead-acid battery, Deep discharge battery Polarity Reserve Protection: Yes Charger available I/P range: 90~280V CHARGER Constant Current Charger Voltage:28.6VDC 2% Floating Charge Voltage: 27.4VDC 2% Maximum Charge Current: 10A or 20A DC Start Voltage: >22VDC PHYSICAL Dimension, D X W X H (mm): 350 x 90 x 300 Net Weight (kgs): 5.5 Warranty:1 year
