The inverter rectifies the voltage which is applied from the controller. The display unit displays various colors according to the voltage which is applied from the inverter. The display unit includes plural fine circuit boards and 3-color LEDs. The 3-color LED displays red, green, and blue arrows according to the voltage from the inverter. |
