偶得100%新1臺，輸入DC40-80V，輸出交流電壓220V，輸出頻率50Hz/60Hz可選，功率3000VA。尺寸：536x348x222毫米，重量約17公斤。
Maximum input current (3 KVA)       < 86A at Sout = 3 KVA at Uin min
                                                                  < 138A during t ≥5 sec at 100% overload and 48V input voltage
Nominal value of output current                               13A at Uout nominal = 230V
Short circuit output current                                       > 36A peak during min. 5 sec

上電了就是不輸出-----，求高手教教我。
