 M-System recommends you to use a voltage divider, model M2VV. The maximum
input range of the AS4V is -10V to +10Vdc so that you cannot input the solar
power system generating power, 0 to 1,000Vdc to the AS4V directly. The M2VV
can step down a voltage value by the dividing rate from 1/300 to 1/1000.
In this case, please specify the dividing ratio 1/1,000. Through the voltage
divider, the output of the M2VV will become to be 0 to 1Vdc, which will
be easily acceptable value for the AS4V.
M2VV doesn't need any auxiliary power and will be easily installed in a
small panel space thanks to its small/ compact size.

If input voltage is up to 600Vdc, isolators like M2VS, SV, KVS and etc.
can be build with special specifications. Please contact M-System for details. |
To monitor a solar power system, we measure an output voltage of its system
and want to receive an alarm outputs if the measuring value fell than a
set value. We had used a DC Alarm, model AS4V previously, but this time,
the measuring voltage range is to be 0-1,000Vdc which is not able to input
directly to the AS4V. Additionally, our existing panel room is not so large.
