DC MOTOR SPEED CONTROLS
KBPW
PWM NEMA 4X DC Drives
The KBPW-240D is a Pulse-Width Modulated (PWM) control in a NEMA-4X
/ IP-65 washdown and watertight enclosure designed to operate
Permanent Magnet and Shunt Wound motors through 7.5 Amps DC. This
provides high motor efficiency, whisper quiet operation along with less
motor heating. This allows for a smaller, less costly motor to be used in
most applications. A unique feature of the KBPW-240D is its active bridge,
which substantially reduces the AC line surge current during cycling of the
AC line. This allows the control to be turned on and off rapidly without
damage to critical components. The active bridge is coupled with a
failsafe circuit that will shut down the control if the main power transistor
shorts, preventing a dangerous high-speed runaway condition. Motor
burnout is prevented with the Timed Current Limit circuit (TCL). Standard
front panel features include diagnostic LEDs for “Power On,” “Stop” and
“Overload,” Start/Stop Switch, and a Main Speed Potentiometer. Optional
accessories for the KBPW-240D include FWD-BRK-REV Switch, On/Off AC
Line Switch, Run-Stop-Jog Switch, Signal Isolator, and an Anti-Plug
Reversing Module™. The control is available in black finish or white FDA
approved finish. See KBPW optional accessories on page 11.
KBRC
SCR NEMA 4X Regen Reversing Drives
The KBRC-240D is a Full-Wave Regenerative Drive in a NEMA-4X / IP-65
washdown and watertight enclosure. It is designed to operate 90 and 180
Volt Permanent Magnet and Shunt Wound DC motors in a bidirectional
mode. It provides 4-quadrant operation, which provides forward and
reverse torque in both speed directions. Motor overload protection (I x t)
will shut down the control if the motor is overloaded for a predetermined
amount of time. The exclusive Auto-Inhibit® circuit allows safe, smooth
starting during rapid cycling of the AC line. The KBRC-240D can be operated from a two or three wire start/stop circuit or can be started from the AC
line. A set of dedicated normally open or normally closed relay contacts
are provided, which are activated via the start/stop circuit. Main features
of the KBRC-240D include Speed or Torque control modes. In addition,
Regenerate-to-Stop (RTS) or Coast-to-Stop (CTS) stopping modes are
also provided. Standard front panel features of the KBRC-240D include
diagnostic LEDs (for Power On, Stop and Overload), a Start/Stop Switch
and a Main Speed Potentiometer. Other features include Barrier Terminal
Blocks, adjustable trimpots, selectable jumpers and LEDs. The KBRC-240D
is available in black finish or white FDA approved finish. Accessories
include: SIRC Signal Isolator (KB P/N 8842), switches for AC Line ON/OFF,
