The product can convert DC 12V into AC 220V, And USB output is DC 5V.Rated output power of the product is 150W, which can be widely used in all kinds of electrical equipment, such as mobile phone, TV set fanner, digital equipmnt.Extended time of soft-start,solve the problem of hine can't got damage from short circuit start . Better to prevent instantaneous large-current and enhance loading capacity.RED and GREEN double working. Green light turn on when normal operation,RED light turn on when protection function start or hine failure.Storage battery will recovering to normal value and offer 3 times for re-start after LVP started.It will stop working after 3 times. First check the problem of frequent LVP and re-start the inverter .(To avoid storage battery working life reduced by repeated Low-voltage )Storage battery will recovering to normal value and offer 3 times for re-start after OVP started.It will stop working after 3 times. First please check the problem of frequent OVP and re-start the inverter .(To avoid storage battery working life reduced by repeated over-voltage )Description:3 times for restoration when overload protection,and power shut offafter 3 times. Protecting battery and enhance loading capacityconcurrently.To avoid short circuit illusion, and strengthening theload capacity,Inverter will stop working when short circuit protectionstarted and offered 3 times. Model can recover normal work under longtime and frequent short circuit.Can load 150W resistive load and 150W inductive load easily,load properties unlimited of 150W power.Allintelligent SCM solutions, stable, output voltage frequency error issmall, with super loading capacity and protection features.
