1kw-4.5kw 3-phase inverters/ups

Product Description

(1) The inverter is designed by our company independently; it’s controlled by CPU, high quality, low cost and the pure sine wave intelligent inverter. (2) The inverter can be used for any loads (including fan, refrigerator, air-condition, water pump electromotor etc). it has solved the square wave, quasi sinusoid output inverter’s disadvantages of doing harm to some loads. Notice: before you use your equipments, you must confirm it’s 1 phase 3 wires (1 is earth) or 3 phases 5 wires (1 is earth). Otherwise it will damage your equipments. (3) Full automatic intelligent switching. (4) Output short circuit protection (when the inverter is working on battery mode): when there is short circuit, the inverter will indicate it and the machine will shut down automatically. (5) Overload protection: when there is overload, the machine will prompt you and protect the inverter from being damaged automatically. Over100%-120%, inverter shuts down about 30s later, over 120%, inverter shuts down at once. (6) Battery protection: single battery voltage is 10V (limited only in the maintenance free). (7) Disturbing power protection: surge protection. (8) City power over-high protection is 480V AC. City power over-low protection is 300V AC or over-high 480VAC. (9) When the city power R-phase is normal, the battery can charge automatically. can use a DB9 cable connecting with your equipments. It need a 6V to15V DC voltage keeping more then 3 seconds.
