Widely used in the fields of post office,store,elevator,hospital,school,publishing house and stock exchange where normal voltage is in need,and also can be used in the factories of large and middle-scale industrial and mining corp,it is very much suitable for some important devices and supporting single machine.
Three-phase four-line system phase voltage:220±20%
line voltage:380±20%,or phase voltage:220±30%
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
1-5%(can be adjusted)Frequency:50HZ/60HZ
≥98%(Power grade 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
≤1s(in the condition that the external voltage changes is 10%)
- Q:3 24V100W lights, I need to use a large capacity transformer (220V change 24V)?
- The quality of transformer itself, coupling coefficient, overload capacity, as well as the impact current of the bulb, filament, cold resistance and simultaneous startup factor, it is better to choose the 400VA transformer
- Q:How to use digital multimeter to detect the quality of 36 volt low voltage lighting transformer?
- General digital multimeter has a capacitor (some of the files with a million capacitance test table of Jack, some use pen)
- Q:Why is elevator lighting transformer installed?
- 1) a lamp shall be installed at the highest and lowest point 0.5m away from the hoistway, and a light shall be installed at intervals not exceeding 7m, and a control switch shall be installed in the engine room and the bottom pit respectively;2) the lighting power supply for car top and hoistway shall be 36V; when 220V is adopted, the residual current action protector shall be installed;3) there is no lighting device for a closed well road with sufficient lighting conditions around the hoistway.
- Q:Can the 500 volt lighting transformer be changed into an electric welder?
- The structure of the electric welding machine is different from that of the transformer, and the magnetic gap of the iron core can be adjusted so that the welding current can be changed. In addition, the output voltage of the welder is also soft
- Q:The transformer zero line has broken, has the result to the household illumination circuit?
- The power supply system in three-phase four line zero line is broken, the breakpoint of the single-phase circuit (220V) electrical burn by voltage to 380V. I met, the incandescent lamp suddenly particularly bright then the blow up of internal fuse TV has burned out. So in the three-phase four wire power supply system zero line asked to do repeat grounding in households is the reason.
- Q:How many power illuminator can 5Kva 36V transformer drive?
- Of course, if you want to bring more is not impossible, but depends on the working conditions, the actual power = nominal power, short time use (to ensure that the transformer temperature rise is not too high) is also available
- Q:How many 40W bulbs can be brought into the 1000VA lighting transformer?
- Connect 220V method, FireWire 220V terminal, zero line 0 terminal, 380V terminal is not connected.Connect 380V method, A phase 380V terminal, B phase 0 terminal, 220V terminal is not connected.
- Q:Line lights, lighting transformers in use!! Can live line work?!! Be afraid of electric shock 40
- What you think? Your light is 220V, right. Over 36V, it's better not to live with electricity unless there is good protection
- 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:Please tell me how to calculate the transformer in the lighting circuit of elevator shaft in building electrical design
- The previous elevator hoistway lighting required the 36V safety voltage, and you can see how many power lamps are required for the hoistway, and select the transformer
