How to choose a model
The basic calculation is >> 1 Fluorescent (FL) = 0.45 Amp
For 20 FL Lamps = 9 Amp
Therefore,we choose >> 10 Amp power controllers >> (PSJP-10)

Remark:
Normally, PSJ lamps power controller is for a single phase. But if there is three phases designed, you need to split into single phase.
For example, if 3 phases have 60 FL lamps (18 Amp), each phase has 20 lamps (9 Amp each.), you need to use 3 power controllers (PSJP-10 AMP). We cannot select 20 AMP Power controllers to control all.
