4 CHAPTER 1 Current Requirements Each UPJ-1P requires approximately 3 A rms max at 115 V AC for proper operation. This allows up to five UPJ-1Ps to be powered from one 15 A breaker at 115 V and up to 9 loudspeakers at 230 V. The UPJ-1P presents a dynamic load to the AC mains, which causes the amount...
