INSTALLATION AND ASSEMBLY
(14) Power supply
1 Power supply voltage
The guaranteed voltage of this system is ±10% of the rated voltage.
But if the impedance of the power wires is high, the voltage waveform will become distorted and show the same
symptoms as when voltage drops abnormally. As the following must be noted even if the voltage is within the
allowable range, check the power wiring again.
¶ The voltage drop from the switchboard to this system is great.
¶ The voltage changes greatly when the power of the system is turned on and off (Roughly 5% of the rated
voltage)
2 Power supply capacity
When calculating the capacity, assume that the maximum power consumption per multi-projection unit is 400
VA by reserving a certain headroom.
Current capacity
Multi-projection units Power capacity RM-V2550BU RM-V2550E
100 V 120V 220V 240V
1 screen 400 VA 4 A 3.3 A 1.8 A 1.7 A
4 screens 1600 VA 16 A 13.3 A 7.3 A 6.7 A
9 screens 3600 VA 36 A 30.0 A 16.4 A 15 A
The current increases as the voltage drops. Design the power supply by reserving a headroom by referring to
the connection description in 3 below. When a single power line (same power distribution panel) is used to
power another system, be careful not to exceeds the power distribution capacity by taking the power consump-
tion of the other system in consideration.
3 Connection
¶ Each multi-projection unit has an AC OUTLET connector, which can accept the connection of up to 2 multi-
projection units in addition to the first multi-projection unit. Do not connect other equipment than multi-
projection units to the AC OUTLET.
¶ Connect the system components so that their current consumption does not exceed the current capacity of
the power distribution panel. Always reserve a headroom when designing the system.
