Consumption indication:
There is a LED which has two colors (green and red) while flashing in the front panel of DRT-341 series.
When consumption happens, the LED will flash and display red. The more quickly LED flash, the more
consumption there is.
Reading the meter:
The DRT- 341D series energy meter is equipped with a 6+2 register. Six integers are marked with black color
and one decimal is marked with red. The DRT- 341D LCD series energy meter is equipped with 6+2 LCD
display which is used as recording consumption and can’t be reset to zero. The reading accuracy is 1/100
kWh.
Record
The DRT- 341D series energy meter can separate records the total power,
phase A, phase B, phase C subentry
power. (
The total power= phase A power + phase B power + phase C power)
Pulse output
The DRT_341D Series DIN rail energy meter is equipped with a pulse output which is fully separated from the
inside circuit. That generates pulses in proportion to the measured energy for accuracy testing. The pulse
output is a polarity dependant, passive transistor output requiring an external voltage source for correct
operation. For this external voltage source, the voltage (Ui) should is 5-27V DC, and the maximum input
current (Iimax) is 27mA DC. To connect the impulse output, connect 5-27V DC to connector 20 (anode), and
the signal wire (S) to connector 21 (cathode).
