Analog Meters Clamping to DIN Rails EQ 35 Data Sheet PQ 35 ZQ 35 Analogue Meter Clamping to DIN Rails Applications Electrical Data The analog EQ 35, PQ 35, ZQ 35 meters, designed for the measurement of current, voltage & frequency in distribution, installations which utilizes 35 mm.DIN rails for equipment mounting. The mounting width is 45 mm. These meters housed in molded Polycarbonate cases are suitable for the measurement of AC current & voltage, DC current & voltage & Frequency. The moving iron meters indicate rms values practically independent of wave - form even of high harmonics. Error of indication may occur for extreme wave - forms (eg. phase getting controls) & for frequencies above 100 kHz. For the CT operated Ammeters, dials can be eld tted based on CT ratio. Frequency meters are designed to measure system frequency from 45..65 Hz with different system voltages. Measuring unit Features • Easy mounting with 35 mm Din-rail. • Near linear scale for EQ & linear scale for PQ & ZQ • Glass lled polycarbonate housing. EQ 35 PQ 35 ZQ 35 moving-iron movements with shell-type system, silicon oil damping and spring loaded jewel bearings, pivot suspension. moving-coil movement with core-type magnetic system, dual spring loaded jewel bearings, pivot suspension. moving-coil movement with core-type magnetic system, dual spring loaded jewel bearings, pivot suspension, alongwith frequency transducer.
