The DHZ+, single-rate, direct-reading three-phase meter in a 4-quadrant design with M-Bus and 2xS0 impulses, MID is a digital single-rate meter for the 4-wire three-phase network for both supply and consumption, as well as active and reactive energy, featuring a 2xS0 pulse output for rail mounting. It is a digital single-rate meter for measuring positive (consumption) and negative (supply) active energy and reactive energy in 4-wire networks. Digital three-phase meter for direct measurement. Display shows energy value, display test, pulse constant, pulse length, power, voltage, current, instantaneous values, power factor, and frequency. Operating button for display switching and device parameterization, installation error detection, 2 x pulse output in OptoMOSFET design, max. 250V AC/DC 100mA (complies with S0 specification) kWh, pulse factor and pulse length adjustable, mounting on DIN rail according to EN 50022 (TS 35). EC type examination certificate for active energy according to Directive 2004/22/EC (MID = Measurement Instruments Directive). Attention! Changes to the pulse outputs are only possible once after installation for calibrated/MID-compliant meters. The meter must then be locked by the meter user. This DHZ+ meter series is also available in other versions, such as for systems in 2-wire / 3-wire / 4-wire and voltages (U) like 1 x 230 V, 3 x 100 V, 3 x 230 V, 3 x 400 V, 3 x 500 V, 3 x 58 / 100 V, and with various other interfaces. Please inquire about the corresponding article number at the factory. Technical data: 4-wire system, voltage (U) 3x230/400V, current (I) 5(80)A, in 4-quadrant design, frequency (f) 50 Hz, display 3-line.
