Basler VR63-4A/UL Instruction Manual

BASLER ELECTRIC,
INTRODUCTION
The VR63-4A/UL Voltage Regulators are
designed for use on 50/60 Hz brushless
generators. The regulator includes frequency
compensation, overexcitation shutdown, a
solid-state build-up circuit, and EMI filtering.
WARNING
To prevent personal injury or equipment
damage, only qualified technicians or
operators should install, operate, or
service this device.

FUSES
It is recommended that fuses with high
interruption capability be installed per the
interconnection diagram to protect wiring from
faults before the regulator. Install 5 A, 250 V
fuses with a high interruption capability in the
lines 3 and 4. Refer to the Interconnection
Diagrams.

Fuse
interconnection diagrams to avoid inter-
rupting the field current.
MOUNTING
The regulator may be mounted in any
position. Refer to the Drilling Diagram.
EXCITER FIELD POWER CIRCUIT (wires F+
and F-).
Connect the regulator wire F+ to the brushless
exciter field terminal F+, and wire F- to
terminal F-.
The dc resistance of the exciter field
must be equal to or greater than 15 ohms
and less than 100 ohms.
