ENERGY METER DSZ15WD-3X5A

Three-phase energy meter for current transformer measurement, with MID approval. The liquid crystal display shows total energy consumption T1 (kWh), total consumption stored in resettable RS1 and RS2 memories (kWh), instantaneous power consumption P (kW), instantaneous voltage U (V), and instantaneous current I (A) per phase. Adjustable current transformer ratios: 5:5 50:5 100:5 150:5 200:5 250:5 300:5 400:5 500:5 600:5 750:5 1000:5 1250:5 1500:5 Maximum current 3x5A. Adjustable transformation ratios for most different current transformers. Standby power consumption only 0.5W per conductor. Modular unit for rail mounting according to standard DIN-EN 60715 TH35. 4 modules = width 70mm, depth 58mm. Accuracy class B (1%). S0 interface. Direct measuring three-phase current meter, measuring active energy based on the electric currents flowing between input and output. The device's own consumption, which is at most only 0.5 watts, or active power of 0.5 watts per conductor, is not taken into account in measurements and does not appear on the display. One, two, or three phase conductors with current up to a maximum of 5A can be connected to the meter. Starting current is 10mA. The N terminal must always be connected. The 7-segment liquid crystal display can be read twice within two weeks without power supply. CT ratio can be changed. Factory setting is 5:5 and locked with a jumper marked 'JUMPER'. If you wish to adjust the CT ratio to match the installed transformer, remove the jumper and reset the energy meter according to the user manual. Then reseal it with the jumper again. Fault indication (false): when a phase conductor is missing or the current direction is wrong, the character 'false' appears on the display and next to the respective phase conductor on the right edge of the display. Important! Before working with current transformers, disconnect the voltage from the energy meter. This product description is an automated translation of the original Finnish description.
