DIN-Rail Power Meter
•
This means that 1 pulse = (1/2200)kWh, therefore 2200 pulses = 1kWh
•
Since we get 2200 pulse/kWh, enter 2200 as the pulse constant into the meter
•
Press “SCROLL” to get to the “S-14 PH” page. This configuration will represent
the pulse width of the pulse that the meter will output. Put in the pulse width
for the pulse output. The range is 20-100ms.

•
A 24V DC supply is required to power the circuit and should be connected to the P2 termi-
nal of the meter.
•
A 1 kilo ohm resistor is suggested to be used in series to limit the current to the P2 terminal
(refer to Figure 3-2 above).
•
The P1 terminal is connected to the positive terminal of the pulse counter.
•
The negative terminal of the 24V DC supply is connected to the negative of the pulse count-
er.
With the pulse output circuit and settings configured the pulse output can be tested. Inject the
meter with both voltage and current to ensure that the meter will accumulate energy and also
output the pulses based on the above settings.
