A.V.R.
2.5 - R438 A.V.R. options
-
Current transformer
for parallel operation
of ....../1A. 5 VA CL 1.
-
Remote voltage adjustment
potentiometer
:
470
Ω
, 0.5 W min: adjustment range ± 5%
(range limited by internal voltage potentio-
meter
P2
). Remove ST4 to connect the po-
ten-tiometer. (A 1 k
Ω
potentiometer can also
be used to extend the adjustment range).
For wiring up the external potentiometer;
the “earth” wires must be isolated as
well as the potentiometer terminals
(wires at the same voltage as the power).
-
R 731 external module
: sensing of 3-phase
voltage 200 to 500 V, compatible with parallel
operation. Disconnect ST1 to connect the
module; set the voltage via the module po-
tentiometer.
- R 734 module
: detection of 3-phase current
and voltage for parallel operation on unba-
lanced installations (imbalance > 15%).
-
R 726 module
: 3 functions (mounted exter-
nally).
P.F. regulation (2F) and voltage sensing cir-
cuit before paralleling (3 F).
- Control through DC voltage
used monito-
ring apply to the terminals for connection of a
potentiometer DC voltage :
• internal impedance 1,5 k
Ω
• ± 0,5V enable a voltage setting of 10%.
