The DDS2015A device is designed to measure the consumed energy ("counter" mode) and current power ("wattmeter" mode) in single-phase AC 220V circuits.
Basic display mode - the amount of consumed energy (it is not reset to "zero", that is, like a conventional electric meter)
On the front panel under the nameplate there is a touch button for switching the mode (the button is located just to the right of the LED indicating counting pulses).
Consecutive pressing of the button calls the following modes:
-
current mains voltage, V
-
current consumed current, A
-
current power consumption, kW
-
return to counter mode
The housing is designed for panel mounting, mounting on a DIN rail.
Readings are indicated on a monochrome liquid crystal display.
The wattmeter can be used for internal metering of energy consumption by individual consumers (boiler, electric furnace), or as an operational control device in the case when regular access to the electricity meter is difficult (for example, the meter is installed in a switchboard room in a multi-storey building).
Attention! The device is not a certified metering device, the readings of the device cannot be used as an official argument in disputes with energy supply companies!

Connecting the appliance
There are two modifications of the device:
1) on the left is the phase, on the right is zero, while the input is from the top, the load is from the bottom
2) zero left, right phase, with input from below, load from above
This can be seen in the pictures with diagrams.
After the wattmeter, it is necessary to install an automatic modular switch, single-pole or double-pole.
