Philips doesn't make arcade monitors. They do however make tubes.
That is a 63 centimeter (25") CRT (tube).
The model number for your monitor as a whole should be on a sticker attached to the metal base plate, frame or some part of the electronics board.
I'm guessing here since I dont have the model #, but I'm sure it requires 110 volts, but also MUST be connected through an isolation transformer. Do not connect an arcade monitor directly to a wall outlet/power strip, lest you blow up the monitor AND your gameboard / other electronics.
The monitor doesn't require a power supply, just an isolated 110 volt power source.
