Notes:
|
|
1.
|
Maximum recommended output is 90 VDC for 115 VAC
and 180 VDC for 230 VAC. Exceeding these output voltages may cause a
reduction in load regulation performance.
|
|
2.
|
For shunt wound motor with lower voltage field, use
L1 and F1 connection.
|
|
3.
|
For Armature Feedback, regulation is % base speed.
For Tachometer Feedback, regulation is % set speed.
|
|
*
|
Regulation is % base speed at full load, 100-130 VAC.

Specifically designed for use with metering pumps,
the NIKKISO HydroDrive DC SCR Variable Speed Drive is a
NEMA 4X (IP-65) variable speed motor control for shunt
wound or permanent magnet motors. Its rugged, die
cast aluminum housing is protected with an acrylic
coating for the ultimate in corrosion resistance,
making it suitable for applications requiring washdown,
watertight integrity. All switches are sealed with rubber
boots, and the manual speed adjustment
potentiometer incorporates a shaft seal.
The NIKKISO HydroDrive electronics are state-of-the-art, and
include short circuit and transient protection to provide
the ultimate in reliability. Electronic overload protection
is also provided, thereby preventing motor burnout and
demagnetization of permanent magnet motors. The
current range is jumper selectable, eliminating the
need for calibration of IR compensation and current
limit in most applications. The Hydrodrive® DC SCR
Variable Speed Drive also contains jumper selections
for AC line voltage (115/230 VAC), DC armature voltage
(90/180 VDC) and feedback type (armature/
tachometer).
Standard features include electronic start/stop, on/off
AC line switch, auto/manual selector switch, manual
speed potentiometer, armature fusing, signal isolation,
and LED indicator array for power on, stop and
overload. Although NIKKISO Hydrodrive controls are typically
factory preset to a specific metering pump, a variety
of trimpots allow easy field adjustment of the following
parameters: minimum and maximum speed,
acceleration, deceleration, current limit, IR
compensation and timed current limit.
