Привод управления скоростью шасси постоянного тока SCR KBIC-240D KB Electronics, 9464

Description The KBIC® full-wave DC motor speed controls are designed for applications demanding excellent performance, high reliability and low cost. Although compact in size (only 4.30″ x 3.64″ x 1.25″), these controls offer better than 2% regulation over a 50:1 speed range. The controls are fabricated with components which have proven reliability, including MOV transient protection, which is used to protect the power bridge. Integrated circuitry is used to provide a non-complicated design with superior load and line voltage regulation. Electronic current limiting (CL) protects the motor and control against overloads by limiting the maximum level of output current. Acceleration start (adjustable from .5 to 4 seconds) provides a smooth start each time the AC power is applied. A unique feature of the KBIC® controls is the Plug-in Horsepower Resistor®. It eliminates the need for recalibrating IR Comp and Current Limit when the control is used on various horsepower motors. Additional versatility is achieved by using the Auxiliary Heatsink (optional) which is used to double the horsepower rating of each model. The output of the control is a linear function of potentiometer rotation. The KBIC® can also be operated in a voltage following mode by supplying an isolated analog signal (0 – 9VDC) to the input terminals P2 (+) and F-. The controls are terminated as standard with Q-D terminals. A Barrier Terminal Accessory Kit is available which incorporates both line and armature fuses. The Inhibit™ circuit (terminals I1 and I2) is provided to electronically disconnect the armature output voltage. Another standard feature is Auto Inhibit®. This circuit prevents false starts and high surge currents when cycling the KBIC® control with the AC line. A variety of models are provided with choices of voltage and current ratings. Model KBIC-240D operates on both 115 and 230 VAC to provide 0 – 90 and 180 VDC output. Model KBIC-240DS operates on both 115 and 230 VAC to provide 0 – 90 VDC output. Included with the controls are a 5K remote potentiometer, mounting hardware and operating instructions. Standard Features Plug-in Horsepower Resistor® (see chart) allows a single model to be used on a wide range of motors MOV Transient Protection Trimpots: MIN, MAX, ACCEL, IR & CL Voltage Following Inhibit™ and Auto Inhibit® Specifications Brand KB Electronics (Nidec) Part Number 9433 Model Number KBIC-125 Maximum Rating 0.75 HP (without Auxiliary Heatsink) 0.56 kW (without Auxiliary Heatsink) 1-1/2 HP (with Auxiliary Heatsink) 1.13 kW (with Auxiliary Heatsink) Input 115 Volts 50/60Hz Max Line Current 12 AC Amps (without Auxiliary Heatsink) 24 AC Amps (with Auxiliary Heatsink) Motor Voltage Range 0 – 90 VDC Field Voltage (Shunt Wound Motor Only) 50, 100 VDC Max Load Current 8 DC Amps (without Auxiliary Heatsink 16 DC Amps (with Auxiliary Heatsink) Net Weight 0.58 lbs (without Auxiliary Heatsink) 0.26 kg (without Auxiliary Heatsink) 2.5 lbs (with Auxiliary Heatsink) 1.14 kg (with Auxiliary Heatsink) Dimension Reference Code ”A” (without Auxiliary Heatsink) ”B” (with Auxiliary Heatsink) Dimensions 4.30″ x 3.64″ x 1.25″ (LxWxH) Without Heatsink 7.00″ x 6.25″ x 2.625″ (LxWxH) With Heatsink Speed Range (Ratio) 50:1 Load Regulation (% Base Speed) 1 (0 – Full Load, 50:1 Speed Range) Line Voltage Regulation (% Base Speed) 1/2 (At Full Load, +/- 15% Line Variation) Control Linearity 2 (% Speed vs Dial Rotation) CL/Torque Range 0-300 % Full Load Acceleration Time Range 0.5-4.0 Seconds Minimum Speed Trimpot Range 0-30 % Full Speed Max Speed Trimpot Range 50-140 % Full Speed Max Allowable Ambient Temperature at Full Rating 45°C 113°F Plug-In Horsepower Resistor Chart The Plug-In Horsepower Resistor (PHR) is supplied by your distributor and must be installed for the control to operate. It is used to automatically calibrate the IR Compensation and Current Limit based on motor horsepower and voltage. It eliminates the need to recalibrate the control in most applications. Select the correct PHR in accordance with the chart below. Be sure it is inserted completely into the mating sockets. 115VAC In 0-90VDC Out Motor HP 230VAC In 0-180VDC Out Motor HP Approx Motor Current (DC Amps) Resistor Value KB Resistor Part Number 1/100 1/50 0.1 1 Ohm 9833 1/50 1/25 0.2 0.51 Ohm 9834 1/30, 1/25 1/15 0.35 0.35 Ohm 9835 1/20 1/10 0.5 0.25 Ohm 9836< 1/15, 1/12 1/6 0.8 0.18 Ohm 9837 1/10, 1/8, 1/6 1/4 1.3 0.1 Ohm 9838 1/4 1/2 2.5 0.05 Ohm 9839 1/3 3/4 3.3 0.035 Ohm 9840 1/2 1 5.0 0.025 Ohm 9841 3/4 ¹ 1.5 ² 7.5 ¹, ² 0.015 Ohm 9842 1 ¹ 2 ² 10 ¹, ² 0.01 Ohm 9843 ¹ Requires optional Auxiliary Heat Sink (KB Part Number 9861) for Operation at 115VAC ² Requires optional Auxiliary Heat Sink (KB Part Number 9861) for Operation at 230VAC
