Schneider Electric Measuring device

PowerLogic PM3255 universal measuring device for DIN mounting with a backlit LCD display (128 x 96 pixels). The measuring device offers an accuracy class of 0.5s according to the IEC 62053-22 standard and 32 samples per cycle. It measures energy, active and reactive power, voltage, current, frequency, power factor, apparent power, total harmonic distortion, and up to the 15th harmonic. With 4-quadrant energy measurement, the device operates in a 50Hz or 60Hz network and accepts a supply voltage of 100 to 277VAC, 173 to 480VAC, and 100 to 300VDC. The rated current is 1 A or 5 A and supports single-phase, single-phase with neutral, or three-phase configurations. The direct measurement range is from 50 to 570VAC, with an external voltage transformer from 570 to 999,000VAC. The measurement range between phases is 80 to 570 VAC at 45 to 65 Hz. The measurement range between phase and neutral is 50 to 330VAC at 45 to 65 Hz. The communication protocol is Modbus RTU and ASCII 2 wires with RS485 connection. Support for two digital inputs and two digital outputs. The device offers 512kB of memory for event recording with up to 15 alarms and power and energy consumption logs. The product dimensions are as follows: width 90 mm, depth 70 mm, height 95 mm, and product weight 260 g.
