Description
The range covers non-programmable voltmeters and ammeters, programmable multi-range instruments, dual and triple indicators, maximum-demand meters, wattmeters and varmeters. The frequency meter DB5RF works in the 30–500 Hz range at 100 and 600 V. DB5RE measures AC current through an x/5 A transformer with a primary current from 5 to 8000 A, and DB5RC measures DC through an x/60 mV shunt. The volt-ammeters DB5RE2D and DB5RC2D have dual indication in two 35×96 mm modules and connect directly up to 80 A. The EM versions (DH5EM, DP46EM, DP35EM) accept an x/5 or x/1 A input and a voltage of 0–200 or 0–500 V, and the CM versions accept x/60 or x/150 mV shunts. DH4EM-A has min./max. contacts for alarms. DMP3 and DMP3B show in turn three line voltages and three phase voltages, three currents and the frequency with an accuracy of 0.5 % of range ±2 counts, updating about 3 times per second. They comply with EN 60051, EN 60068, EN 61010, EN 60529, EN 61000, UL 94, IEC 664, IEC 255.
How to choose
The choice starts with the type of current and the connection method. AC current through a transformer is covered by the EM series, DC through a shunt by the CM series, and direct measurement up to 80 A by DB5RE2D or DB5RC2D. One DMP3 replaces three separate indicators on a three-phase line. The housing is selected to suit the panel cutout, and the supply is specified in the order, for example 110/230/400 V AC, 12/24/48/110/220 V DC or 45–275 V AC/DC. For motor starting currents, take the version with increased overload capacity.
