DESCRIPTION

The EM21072DAV53HOSPFBP is a three-phase energy analyzer designed for comprehensive power measurement and energy management applications. It features Class B (kWh) accuracy according to EN50470-3, Class 1 (kWh) according to EN62053-21, and Class 2 (kvarh) according to EN62053-23, with measurement accuracy of ±0.5% RDG for current and voltage. The device supports flexible current input options via external current transformers (5A CT), 333 mV current sensors (CTV series), or ROG4K Rogowski coils without external integrators, and accommodates voltage measurements through direct connection or potential transformers. It provides instantaneous variable readout with 3-digit display, energy readout with 7-digit display, and measures system variables including W, var, PF, Hz, and phase sequence, along with single-phase variables such as VLL, VLN, A, PF, and THD up to the 15th harmonic. The analyzer operates with self-power supply from 40V to 480VAC (45–65 Hz), offers a pulsating output for active energy retransmission, and includes optional 2-wire RS485 communication. Its multi-use housing accommodates both DIN-rail and panel mounting with IP40 front protection, making it suitable for industrial energy monitoring, power quality analysis, and demand-side management systems.
