Schneider METSEPM5761

The PM5761 is a universal measuring device for front mounting (96 mm x 96 mm) with a fully graphical and backlit LCD display. This device, with an accuracy class of 0.2S (according to the IEC 62053-22 standard), measures energy, active and reactive power, voltage, current, frequency, power factor, and harmonic analysis up to the 63rd. It features 1.1 megabytes of memory for up to 14 selectable parameters with configurable intervals and durations. Additionally, it has direct monitoring of neutral current, earth fault monitoring with earth fault current calculation, and a disturbance recorder function for grid oscillography in case of events, with up to 128 samples per period over 8 periods for under- and over-voltage events. It is suitable for 50 Hz or 60 Hz applications and supply voltages ranging from 100 to 480 VAC and 125 to 250 VDC. The rated current for this measuring device is 1A or 5A, and it supports 1P+N, 3P, or 3P+N configurations. The measurement voltage range between phases is 20 to 690 VAC at 45 to 65 Hz, while the measurement range between phase and neutral is 20 to 400 VAC at 45 to 65 Hz. Communication options include Modbus RTU (RS485), Modbus TCP (Ethernet), and BACnet/IP. The embedded communication functions support the DNP 3.0 protocol, provide access to an integrated web server, and include a serial-Ethernet gateway. The device also features two digital inputs with WAGES support, two RCM inputs, and two digital outputs. There are 52 configurable alarms, and it supports eight tariff plans. The PM5761 is MID compliant and can thus be used for billing purposes. The product dimensions are as follows: width 96 mm, depth 77 mm, height 96 mm, and weight 450 g.
