2 / 4 page  DIN RANGE PANEL METERS MOVING IRON Types: D48SD, D72SD, D96SD. Accuracy: Class 1.5 (Class 2.5-60A and above). AC ratings: 1A to 100A direct connected (D48SD - 40A max). 1A or 5A CT operated. 30V to 600V direct connected. Burden: 0.7VA typical for 1A or 5A CT operated at 50Hz. 1.2VA max up to 30A 2.4VA max for 40A to 100A. 6VA max for voltmeters up to 600V. Frequency: Calibrated at 50Hz. Specify for frequencies 15Hz up to 400Hz Scaling: Standard ammeter and voltmeter scales.(2x and 6x overload amme- ter scales available on request). Damping: Heavily damped movements available. MOVING COIL Types: D48MC, D72MC, D96MC. Accuracy: Class 1.5. DC ratings: 100µA to 50A direct connected (D48MC - 40A max). 4-20mA, 1mA or 20mA transducer operated. 50mV to 600V direct connected. 50mV to 300mV shunt operated. AC ratings: Rectifier types available for a.c. use (mean sensitivity). DC burden: 80mV to 150mV volt drop for direct connect ammeters 1mA (1000 Ω/V) for voltmeters and shunt operated ammeters. Non std.: Suppressed zero voltmeters and trim potentiometer types available. WATTMETER Type: D96WA. Accuracy: Class 1.5. AC ratings: 1A or 5A CT operated. 63.5V to 500V direct connected. Burden: Current<0.5VA Voltage<2.0VA each circuit. Working range: Current 0-120% Voltage 75-125%. Frequency: Calibrated for 50Hz or 60Hz. Systems: WA1 Single phase. WA2 3ph 3 wire balanced load WA3 3ph 4 wire balanced load WA4 3ph 3 wire unbalanced load WA5 3ph 4 wire unbalanced load Terminals: Screw clamps - connection diagram supplied. } CONNECTION DIAGRAMS All DIN range panel meters are available as Wattmeters using a separate transducer. Moving Iron panel meters can be used for D.C. operation at reduced accuracy.
