Description
The PM5661 is a universal measuring device for front installation (96 mm x 96 mm) with fully graphical and backlit LCD display. The instrument with a precision class of 0.2S (according to the standard IEC 62053-22) measures energy, active and reactive power, voltage, current, frequency, Power factor and harmonic analysis upto 63. With 1.1 MB of memory for up to 14 selectable parameters with configurable interval and duration. In addition, it has a direct monitoring of the neutral conductor current as well as a fault current monitoring with calculation of ground-fault current (residual current measurement RCM). Suitable for 50 Hz or 60 Hz applications and supplies ranging from 100 to 480 VAC and 125 to 250 VDC. The rated current for this meter is 1A or 5A and it supports 1P+N, 3P or 3P+N configurations. The range of the measured voltage between the phases is 20 to 690 VAC at 45 to 65 Hz, the measurement range between the phase and neutral is 20 to 400 VAC at 45 to 65 Hz. Communication options are Modbus RTU (RS485), Modbus TCP (Ethernet), (with 2 RJ45 ports, switched, same IP) as well as BACnet/IP. The embedded communications capabilities enable support of the DNP 3.0 protocol, access to an embedded Web server, and a serial Ethernet gateway. The meter also has two digital inputs with WAG support, two RCM inputs and two digital outputs. There are 52 configurable alarms and it supports eight rate plans. The PM5661 is MID compliant and can therefore be used for counting off. Product dimensions are as follows: Width 96 mm, depth 77 mm, height 96 mm and weight 450 g.
