(1) The uncompensated inductive ballast circuit consumes twice the output current of each set of lamps, so it is seldom used.
(2) The total capacitance of shunt power factor compensation capacitors limits the number of lamps controlled by a contactor. The rated power is the limit value of the total capacitance of the standard contactor lower circuit of 16A, 25A, 40A and 63A, and the corresponding values that cannot be exceeded are 75, 100, 200 and 300 uF. If the capacitance value is different from the value in the table, it is allowed to calculate the maximum number of connected lamps according to the capacitance limit value.
(3) High-pressure mercury lamps with 120W, 250W and 400W power without triggers will gradually replace high-pressure sodium lamps with 10W, 220W and 350W corresponding power with triggers.
