4.3.2 Auxiliary Power Supply

The unit can be powered from an auxiliary a.c. or d.c. supply that is separate from the metered supply. Versions of the unit are available to suit 100-200V 45-65 Hz a.c./d.c. and 12-48V d.c supplies.

Standard supply voltage	100 to 250V a.c. nominal ±15% (85V a.c. absolute
	minimum to 287V a.c. absolute maximum) or 100V to
	250V d.c. nominal +25%, -15% (85V d.c. absolute
	minimum to 312V d.c. absolute maximum)
a.c. supply frequency range	45 to 66 Hz or 360 to 440 Hz (Model 0440)
a.c. supply burden	3W
d.c.supply	12 to 48V d.c.. nominal +25%, -15% (10.2V d.c. absolute
	minimum to 60V d.c. absolute maximum)
d.c. supply burden	3W
