Filter Capacitors
VTS diodes
Snubber Circuit Ready
Voltage Requirement:
A single DC Source Voltage (unregulated) with any voltage value from 9V to 50V (for Vp)

 

 Si5HyUdMCPS1-50V-20A, Spec Sheet  (PDF)


The Si5HyUdMCPS1-50V-20Ais a 50V 20A, Single, open-loop, microprocessor based, Hybrid, Unidirectional, Motor-Controller board with an Integrated Heat Sink that uses pulse-width modulation (PWM) for efficient control of a load (or brush type DC motor) in the 0 to 1000W power range in 8.3W steps. The desired motor speed (or load current) is set by an external analog voltage (0 to 5V range) but the motor motion is initiated by a reflective infra-red (IR) proximity  sensor which keeps the motor turning long as an object is in the view of the sensor. This sensor has an approximate range from 0 to 0.2”.  An onboard microprocessor generates a 5kHz or 20kHz PWM carrier signal, controls the load-power (or motor speed) and monitors the sensor inputs. The PWM carrier frequency is user selectable by the jumper CN3, 20kHz when CN3 is open and 5kHz when short. The high frequency PWM rate provides a smooth motor-speed control, and insures a quiet motor environment. As the name hybrid (Hy) implies, the required motor speed (or PWM pulse-duration) is derived from a variable analog-voltage (VP1,G), while the other control-signals are digital. This analog (VP1,G) input is zener-diode protected. The user can choose between slow or fast motor acceleration/deceleration modes by short-circuiting or open-circuiting the pins labeled J1M. The slow mode, with rise-time/fall-time of 0.5s, is selected by short-circuit (J1M jumper installed); while the fast buildup mode, with rise-time/fall-time of 0.025s, is selected by leaving these pins open (no Jumper installed). All control lines (analog and digital) are sampled approximately at 700Hz rate in the fast mode, and at 20Hz rate in the slow mode. An onboard LED (red) is used to monitor the load-voltage and an optional. A small (2.3”x2.4”x0.45”) finned integrated heat sink is included with mounting hardware (as shown on the photograph) to operate at 20A or 1000W power levels. Higher power-levels (50V, 30A or 1500W) can be achieved with more efficient heat-sinks. Please click on this link and read the Board Mounting Instructions and Heat Sink Selection Guide. This board requires a single 9V to 50V DC power source (unregulated and unfiltered) at a 0A to 20A current range to operate normally. Typical object triggered applications are: DC Motor-Speed Controller, Light-Dimmer with variable delay, Power Amplifier, SPST Solid State Relay, etc. 

 A Typical Application of the Si5HyUdMCPS1-50V-20A

In this object-triggered application, the motor motion is triggered by a reflective IR proximity sensor with a proximate range from 0 to 0.2”. This sensor can be ordered from Signal, Si6IROsens (sensor with 8” wires and 3-Pin connector) or can be purchased from www.digikey.com (using the part number QRD1114-ND). The PWM pulse-duration (or motor-speed) is linearly adjusted with Si5Pot1-5k accessory (an external 1-turn 5kW pot); and efficiently controlling the motor power in the 0 to 1000W range in 8.3W steps. The DC Motor can be purchased from Bodine, www.bodine-electric.com ; or from other vendors, http://www.e-motorsonline.com/emotors/dcmproduct_list.php .
