PZ72-DE DC Energy Meter
Function
Measures DC voltage, current, power, total energy, forward energy and reverse energy. Voltage input options: 0–100 V, 0–500 V or 0–1000 V DC. Current is measured through an external shunt or Hall current sensor. Accuracy: Class 0.5.
75 × 75 mm front panel, 67 × 67 mm cutout and 98 mm depth. LED display. Optional RS485 Modbus-RTU communication; depending on the ordered suffix, the meter may also provide 2DI/2DO or 12 V sensor power output.
