Line voltage definition

Line voltage means the voltage provided to the trolleybus from the external power supply. Trolleybuses shall be designed to operate at a rated line voltage of either: (a) 600 V (a working range of 400 to 720 V, and 800 V DC for 5 minutes); or (b) 750 V (a working range of 500 to 900 V, and 1,000 V DC for 5 minutes); and (c) Withstand over-voltages of 1,270 V for 20 ms." 1.2. The electrical circuits of a trolleybus are classified according to their rated voltage in the following classes:

Line voltage. Outdoor: 208-240 Vac, 50 to 60 Hz, single phase. Indoor: The Indoor version of the BTS must support both DC and AC power supplies as follows: DC: +25V to + 28V at Minicell input. AC: 110-220 Vac, 50 to 60 Hz, single phase (This will be input to the power cabinet and the power cabinet will provide the required DC input to the Minicell).
