WTS238-IVAP
Winston
Products Description
The meter is used in three phase four wire power grid. The meter is designed to measure
AC active energy and variable parameter.It has remote read by WIFI (Smart life or smart APP).
It is a long life meter with the advantage of high stability, high over load capability, low power
loss and small volume.
Functioning
■LCD display with backlight , keypad for LCD display step by step
■Bi-directional total active energy measurement , reverse active/ energy measure in the
total active/reactive energy
■The meter LCD also display real voltage, current, active power, reactive power , power
factor, frequency, import active energy,export active energy, reactive energy
■Overvoltage protection, overload protection, voltage unbalance protection which can
set by APP or by button
■reverse phase sequence protection which function can be on/off by button
■Lose phase indication , and still measure lose one o two phase under three phase four
wire connection
■Timing control by APP
■Hour/Day/Month/Year history active energy consumption tracking by APP
■check the real current , voltage, active power by APP
■WIFI communication, can read and remote control on/off by mobile phone APP
■Prepayment function ,if balance used up, it will cut off automatic. This function can be
on/off by APP.
■It compatible with TUYA saas system
■Manual Control by button with mode 4 under lose WIFI
■Voice control: once you have this switch, you can connect it with Amazon Alexa
(Amazon echo/ dot/tap) or Google Assistant for voice control
■Pulse LED indicates working of meter, Pulse output with optical coupling isolation
■Energy data can store in memory chip more than 15 years after power off
■35mm din rail installation , bottom type wire connection
