SPECIFICATIONS OF MOVING IRON PANEL METERS

YOKINS' MOVING IRON PANEL METERS (TYPE SR-144,SR-96,SR-72)

These are repulsion type moving iron system having high torque to weight ratio. Instruments are highly damped with best jewel bearings, incorporated with hardened and precisely polished pivots and chemically treated hair springs for corrosion protection. The whole profile looks elegant and in complete harmony with the latest modular design.

VOLTMETERS

RANGE	10V-600V
	Higher voltages can be printed on dial with proper P.T.Ratios

The normal working frequency range is 50-60hz

AMMETERRS
Ammeters upto 50Amps are self contained. Above this range e.g. to measure 100A, use 100/5 current transformer in conjunction with 0-5A meter of any size. The scale on the above meter will be printed as 0-100A and C.T. Ratio 100/5A. Also suppressed scale ammeters with ratio of maximum 1:6 can also be provided.

RANGE	Ammeter	1A - 50A	Above 50 A use C.T.
	Suppressed scale	1/6A,3/18A,5/30A,10/60A, 20/120A,30/180A	Above 50 A use C.T.

Suppressed scale Accuracy in Ammeters (2 X Specified Accuracy)

TYPE	FRONT(sq.mm.)	PANEL CUTOUT	SCALE LENGTH	ACCURACY
