data sheet pxj pxj5 pxj3 fc series receiving instruments, converters, computa- tional units and distributors which are mountable on instru- ment panels are designed in principle for a power supply of 24v dc. type pxj is a regulated-voltage power supply to be used as a common system power supply unit for providing 24v dc to the panel-mounted instruments from a commercial line power outlet of 100v ac. it adopts a switching regulator system for realizing a compact and highly efficient common system power supply unit. it is also prepared as a common system power supply unit equipped with a battery backup system which permits parallel operation to assure failure- free power supply of even higher reliability. the power supply unit can be equipped further with a protective function against line power failure in cooperation with a digital component. input power supply: 100v or 115v 10% ac, 50/60 hz, single phase output voltage: 25.8v 0.5% dc (with pxj5) 25.8v % dc (with pxj3) output capacity: pxj5 10a pxj3 3a parallel operation: possible for pxj5 only backup with batteries (option): possible for pxj5 only (110v % dc from dc power source or batteries) protective function: protection against shorting (overcurrent drooping characteristic, automatic re- covery ) protection against overvoltage (output voltage interruption at overvoltage, manual reset) efficiency: pxj5 85% typical (100v ac, load 10a) pxj3 80% typical (100v ac, load 3a) input current: pxj5 4.7 a rms typical (100v ac, load 10a) pxj3 1.6 a rms typical (100v ac, load 3a) fc series system power supply unit specifications +0.5 ?.0 +30 ?0 date EDS13-14D aug. 31, 1994
