kW transmitter FPA38

Transmitter for kW, 3-phase symmetrical load
Connection to 3-phase net up to 3 x 500 VAC
Monitoring of total power consumption (Ö3 x U x I x cos j)
Built-in current transformer, ranges up to 60 AAC
Analogue output 0-20 mA / 4-20 mA
24 DC supply
Galvanic separation, input - output
Made in accordance with the
and EMC regulations
FPA38 is monitoring the power consumption on 3-phase
symmetrical load, primary motors.
The wanted metering range is selected by means of
DIP-switches, from 0-3,46 kW up to 0-41,6 kW at 3x400
VAC supply, proportional to 0-20/4-20 mA on the metering output. 0-10 V is also possible, see below.
The supply voltage, 24 VDC, and the 3 voltage phases are
connected to the relevant terminals. The current is monitored by putting the current phase L1 through the built-in
current transformer, see connection diagram.

LOAD
Metering principle.
The FPA 38 is connected to the supply, 3-phase net and
load as shown above.
It can also be used together with frequency converters, as
it operates in the frequency range10-150 Hz.
For monitoring of 1-phase loads, connect L2 and L3 to N,
and L1 to the phase.
Since the unit is calibrated for 3-phase loads, the output
signal must be multiplied with 1.5 in order to get the correct value at 1-phase loads.
