The KB Electronics KBPC Series NEMA-4X (IP-65) SCR DC Motor Speed and Torque Control is designed for applications requiring washdown and watertight integrity. Its housing is ruggedly constructed of die cast aluminum which is protected with an acrylic coating. Exclusive Short Circuit and Timed Current Limit (TCL) circuitry prevents motor burnout and demagnetization of PM motors. Features such as Selectable Current Range eliminate unnecessary calibration of IR and current limit trimpots. Other selectable features are: Input voltage (115, 208/230 Volts AC), Output Voltage (90, 180 Volts DC), Current Range (2.5, 5, 7.5, 10) amps, Input Signal (0-5, 0-20) Volts DC, Armature or tach feedback, Tach voltages (7, 20, 30, 50 Volts/1000 RPM). Trimpot Adjustments include: MIN, MAX, ACCEL, DECEL, IR, CL and TCL. Standard features include: Armature Fusing, Electronic Start-Stop and diagnostic LED Indicator Array for "Power On", "Stop" and "Overload". The KBPC-225 contains all of the features of the KBPC-240D except Armature Fusing. In addition, it is designed specifically for 3HP - 180 VDC PM or shunt motors operating from a 230VAC line. Accessories include: KBSI-240D Signal Isolator, Electronic Fwd-Brk-Rev containing APRM-PC, hesitation type Fwd-Brk-Rev switch kit and switches for AC Line ON/OFF, Run-Stop-Jog and Auto/Manual. Dimensions (L x W x H approx.): 5.9" x 10.0" x 5.0".
