Chapter 1 Meter Overview
DZS100-4P is an advanced, smart single-phase DIN rail energy meter. It meters electric
parameters of single-phase current, voltage, power, energy, frequency, power factor etc.
with high accuracy. It is LCD display and also equipped with RS485 communication and
pulse output.
I
ts main functions are as follows:
◆
Measure import active energy and export active energy;
◆
Measure combination of active energy, which is equal to the sum of import active energy
and export active energy
◆
Measure all instantaneous values of electric parameters, including voltage, current,
power, energy, frequency, power factor etc.;
◆
LCD displaying voltage, current, power etc..
◆
Automatically blocking and saving the blocked energy of last 12 months
◆
Timing Records with saving last 10 times of recording moments
◆
Loading data storage with recording data such as voltage, current, power, frequency,
power factor and active energy;
◆
Compatible with DL/T645-2007, DL/T645-1997 and Modbus-RTU protocols.
