Power factor (cos φ) regulator
model HPR6, HPR12
Installation and user manual
Installation
Verify that the regulator supply voltage is
consistent with the voltage of the power grid
(90 .. 550V). The power factor correction
regulator shall be wired as shown in the
diagram below, with the short circuit protection
fuses as shown, size 10 A.
Description of the terminals:
S1 and S2: wires k and l (L lowercase)
from the secondary coil of the current
transformer (CT) installed on the phase
L1 (R).
U1 and U2: regulator power supply and
voltage measurement.
C: common terminal of the bank control,
that has to be protected with a fuse of
size 10 A.
1, 2, ..., n: capacitor banks control.
