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:1000 square meters low voltage.36 volts lighting power supply with multiple transformers and wires
- First of all, make sure your power is too large, but you are not recommended to do so, the cost is too high, the pressure drop is too large, you can raise the voltage to 220V or higher, and then transfer to avoid power losses. If the direct transmission, the power is slightly larger, the line will be very rough, the cost will be very high
- Q:Which is more energy saving by using 24V500W transformer lighting and 220V500W lighting?
- 220V500W more power saving:Reasons: 1, high voltage, small current, line loss is small; 2, reduce the transformer and other intermediate links, each link has a loss.
- Q:How is the lighting power of the 380V transformer calculated?
- The transformer (Transformer) principle should change the AC voltage of the primary coil, the main component of the device level by using electromagnetic coil core (core) main functions: voltage transformation, current transformer, impedance converter, isolation, voltage regulator
- Q:3 24V100W lights, I need to use a large capacity transformer (220V change 24V)?
- Pure resistive load, the power factor is 1.3 *100W=300W, is required for the capacity of the transformer.
- Q:Lighting, lights, transformers, bulb brightness is too low, what's the matter?
- Generally, the power of the transformer is the apparent power, and the light bulb is the active power, and the power matching is taken into account.
- Q:Line lights, lighting transformers in use!! Can live line work?!! Be afraid of electric shock 40
- Line lights, lighting transformers in general how many low voltage, can live operation, but to do safety measures. For example, do not short-circuit, damp environment, wear insulation shoes, wearing insulating gloves and so on.In fact, all the voltage levels, as long as safety measures can be done live operation.
- Q:What's the function of the lighting transformer?
- Illumination transformer: usually refers to the secondary output voltage for the safety voltage 24V - 36V, only for special lighting power supply using voltage converter.
- 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?
- The quality of transformer itself, coupling coefficient, overload capacity, as well as the impact current of the bulb, the cold resistance of the filament and the starting factor at the same time, it is better to choose the 400VA transformer.
