Three-Phase WiFi Meter with 60A Electricity Meter
DTS238-7 ZN/S three phase din rail type multi-function watt hour meter(D3703)
The meter is used in three phase four wire power grid. The meter is designed
to measure AC active energy and variable parameter. All of its functions
comply with the relative
technical requirement for class 1 three phase watt hour meter in IEC61036 and
its data communication rules obey the requirement of DL/T645 or MODBUS-RTU. It
is a long life meter with the advantage of high stability, high over load
capability, low power loss and small volume.
Basic Function
★LCD display with backlight
★Bi-directional total active energy measurement, reverse active/ energy
measure in the total active/reactive energy
★ The meter also display real voltage, real current, real power, real power
factor, real frequency, import active energy, export active energy
★Keypad for LCD display step by step
★Pulse LED indicates working of meter, Pulse output with optical coupling
isolation
★Loss phase indication in LCD
★Energy data can store in memory chip more than 15 years after power off
★RS485 communication port, MODBUS-RTU protocol
★35mm din rail installation
Optional Function
★reset energy function(the reset energy kWh display is dependent with the
total energy display, this reset will not affect the total energy)
