KBPW
PWM Drive - NEMA 4X / IP 65
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.
