line voltage:380±30%(can be selected.Please specify when ordering)
Single-phase:220±20% or 220±30%(can be selected.Please specify when ordering.)
Phase voltage:220V Single-phase:220V Line voltage:380V
Output voltage accuracy
2-5%(can be adjusted)Frequency:50HZ/60HZ
≥98%(Power grade is over 50KVA)
The voltage for electrical strength and power frequency sinusoidal is 2000V without breakdown and flash over when lasts 1minute
It can last 1 minute at the rated current of two times
Wave form Distortion
No additional waveform distortion
it offers the protections against over voltage,over current,phase shortage and phase-sequence(The single-phase offers no protection against the phase shortage and phase-sequence)and mechanical failure
≤1.5s(in the condition that the external voltage changes is 10%)
- Q:What type of low voltage transformer should be adopted for safety lighting power supply?
- We have produced many low voltage lighting transformers, such as outdoor waterproof, high-power stage lighting, as well as indoor small power transformers, customer response, but also good! For example, Guangzhou Color Art Lighting Co., Ltd., before them, our reputation is good!
- Q:Which is more energy saving by using 24V500W transformer lighting and 220V500W lighting?
- If the transformer is not calculated, the loss is the same. If the calculation is the latter, save electricity.
- Q:Is the substation separate from the power and illumination transformer?
- The power and illumination of the substation are all used on a transformer, which is separated by power and lighting by the station screen of this transformer.
- Q:How to calculate the rated capacity of small transformers for lighting purposes?
- Capacity of power transformer is the basic equipment for a total capacity of [kW] (maximum power consumption rate by a / X100 capacity) divided by the power load [%] value for benchmarking.
- Q:How many power illuminator can 5Kva 36V transformer drive?
- The load capacity of the transformer is 70% of its nominal power, so it is concluded that the transformer you provide can drive the 3.5KVA 36V lighting appliance (which is used in normal condition and environment)
- 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: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 is the two side of the lighting transformer grounded?
- Neutral grounding of three-phase transformer is called working earthing: the main function is to strengthen the stability of low-voltage system potential, and to reduce the risk of overvoltage caused by grounding, high voltage, short circuit, etc..
- Q:What's the function of the lighting transformer?
- Applies to some requirements for safe voltage 24V - 36V lighting sites. Such as: basement, tunnel, dangerous goods warehouse and so on. Then there is the (mobile, temporary) safety lighting for the overhaul.
- Q:What transformer can be used in a safety voltage lighting transformer?
- Early European countries used in the power industry, widely used in the electronic industry or industrial and mining enterprises, machine tools and machinery equipment general circuit control power supply, safety lighting and indicator light power supply.
