Tips from our experts
You’ve got LOADS of LUMENS with your DP Projector…
but do you have the RIGHT Power?
Is it 110 or 208? Can the projector run at lower brightness at the lower voltage? Do I have the right connector? The right amperage available? The right receptacle for the power cord? NEMA 5-15, NEMA 6-15, L6-20, L6-30?!?!?! There are so many questions! Our Techs come across this too, so here is some advice from the pros:
POWER: A projector’s power requirement is generally proportional to its light output.
- Although some of today’s laser projectors have power requirements similar to older lamp-based units, current laser projection light outputs have increased greatly. These higher lumen projectors require a larger and proportional amount of wattage for driving the laser light engine. ( Note: a small percentage of power is dedicated to the control/processing circuitry. The majority of power is used in producing the light. )
- Lower lumen projectors can safely run on 110V AC and still be allowed the use of full laser power
- High lumen projectors will require 208V (200 – 240V AC) for full laser power
- Some mid - high lumen units allow the use of either 110V or 208V, however their output is reduced to about a 65 – 70% output when used on 110V. This ultimately has to do with the amount of wattage required to power the full set of lasers at full power. In contrast, if the laser’s power is reduced, then the projector’s total wattage requirement is less and it could feasibly run on a 110V circuit
- HIGHlite 4K-UHD, HIGHlite II 3D, E-Vision 13000WU, M-Vision 18K, and M-Vision 21K must all use a 220V supply in order to achieve full light output
This means that a 110V 15A circuit can only support a total load of 1,650W. We should also remember that there is a peak power requirement during projector startup, and we should leave a little unused headroom for this so as not to overload the circuit and push it to its limit.
If we then know that a high lumen projector requires 3,400 watts, then we can calculate the minimum amperage required for the circuit breaker ( 3400W / 208V = 16.3A ). A 220V 20A circuit would be appropriate for this 16.3 amp requirement.
In contrast, if we were to try and use a 110V circuit ( 3400W / 110V = 30.9A ), this 30.9 amps would not be possible. A 110V 15A circuit is the norm in most residential and commercial spaces. A 110V 20A circuit is available, but requires heavier wiring, and a 110V 30A circuit does not exist.
POWER CORD & CONNECTORS:
|HIGHlite 4K-UHD, HIGHlite II 3D, E-Vision 13000WU, M-Vision 18K, M-Vision 21K
Projectors drawing less than 15 amps @208V - standard 220V power cord is a C19(R) to Nema 6-15P. If supply has an L6-20R or L6-30R connector, then the cord’s 6-15 connector can be removed and replaced with required 220V type.
On projectors drawing 15 to 30 amps @208V, the standard 220V power cord is a Nema L6-30R to Nema L6-30P.
Lower lumen projectors drawing less than 15A @110V can be operated on a normal 110VAC 15A circuit. The supplied standard 110V power cord is a C13(R) to Nema 5-15P (all E-Visions except the E-Vision 13000WU).
