Product Description:



This inverter is a DC-TO-AC inverter with auto line-to-battery transfer and integrated charging system, serving as an extended run UPS, a stand alone power source or an automotive inverter.


Inverter supplies power from AC power and DC source. When AC cable is connected to a wall socket, utility power goes to connected equipment(s) and /or charges the battery set via charging system. In UPS mode, Inverter automatically converts battery energy into AC power for backing up the connected devices.


· Automatic line-to-battery switchover


· Selectable input voltage ranges


· High efficient DC-to-AC conversion, minimizing energy loss


· Rack tower design for flexible placement


· Built-in enhanced charger


· Intelligent 2-stage charger control for efficient charging and preventing overcharge


· Provides overload protection


· Auto restart while AC recovery


· Multi-function LED indications and buzzer alarms

Q:What type of low voltage transformer should be adopted for safety lighting power supply?
Isolated transformer, once 380V or 220V, two voltage, 36V, 24V, 12V, several categories, do not allow the use of autotransformer.
Q:How is the lighting power of the 380V transformer calculated?
Special transformer power transformer (electric furnace transformer, rectifier transformer, power frequency test transformer, voltage regulator, transformer, audio, mine variable frequency transformers, high frequency transformer, transformer, instrument transformer, impact power transformer, reactor, mutual inductor etc.) circuit with T symbol number. For example: T01, T201 etc.
Q:Power and lighting transformers, lighting quality will be affected much?
First look at this light. 24V100W, this specification is common in the headlights of large trucks, filled with inert gas, known as the small sun. Its power comes from a generator or battery, and is lit by alternating current or direct current.
Q:Why should lighting transformers be used in factories and mines?
But in many cases, such as mines and machinery, the voltage is too high and unsafe. The lighting transformer is then used to reduce the voltage to the so-called "safety voltage""
Q:Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.
The self winding transformer is connected by all its windings, and depends on the position of the sliding contacts to change the magnitude of the voltage. Therefore, there is not only a magnetic connection between the primary winding of the autotransformer (the power circuit) and the two winding (the power supply circuit), but also the direct connection of the circuit. It forms a circuit with the earth, so it can not be used as the power source of the safety voltage
Q:Line lights, lighting transformers in use!! Can live line work?!! Be afraid of electric shock 40
General line lights are 36 volts, especially in the damp and harsh environment, the light transformer adopts 24 volts voltage;After the use of light transformers, can generally live operations, first, low voltage, less dangerous, and the two is a transformer isolation, safety is greater, so you can live work, generally there will be no electric shock accident. (as long as the power is not in the hands and hands, the two end of the power supply, there will be no electric shock.)
Q:1000 square meters low voltage.36 volts lighting power supply with multiple transformers and wires
To 30VA/ square meters, the transformer needs 30KVA, with two 120 square copper wire. Specific should be used to determine the total power of the lighting transformer.
Q:How many 40W bulbs can be brought into the 1000VA lighting transformer?
Because some transformers are connected to 380V and 0, they can be 1000VA capacity, but because of the same line diameter, the 220V terminals and 0 can not provide the capacity of 1000VA.
Q:Why can't autotransformer be used as transformer for safety lighting?
The transformer of the lighting circuit is a step-down transformer (general input 10kv., 220V). The first coil of the autotransformer is shared and connected together
Q:The transformer zero line has broken, has the result to the household illumination circuit?
No, the zero line of the transformer doesn't go through the zero line of the transformer. It is a star connection, and the center point is zero line
