 Si5PumpC1-30V-20A, Spec Sheet  (PDF)


The Si5PumpC1-30V-20A is a 30V 20A microprocessor- based pump controller with an integrated heat sink that softly turns the current on or off to a 12V to 24V, 500W DC motor when the proper battery voltage and fluid levels are acquired. At power turn-on, the battery voltage is measured and the motor is turned fully on if the battery voltage is greater than VBH and the fluid level is low (VBH=Threshold Voltage High, user adjustable via. 25Turn Trim-Pot, P1); otherwise the motor current is turned off. Once the motor is running, it will be kept in the ON-state until the battery voltage is reduced below VBL, (VBL=Threshold Voltage Low, user adjustable via. 25Turn Trim-Pot, P2); at this point, the motor turns off. A 5 Sec loop-delay is included to prevent motor chatter. An external, normally-closed or normally-open (J1= Short=Normally-Open, J1= Open=Normally-Closed) mechanical float-switch is used to stop the motor rotation whenever the fluid tank is full. This switch is connected to CN3; it is always active and overrides all other control conditions. The threshold voltages VBH and VBL are user adjustable with factory default values of: VBH = 15V and VBL =8V. The soft Motor Turn-ON/OFF uses 5kHz PWM speed control with 1.2sec ramp time. This feature assures long motor life. An onboard LED (red) is used to monitor the load-voltage. The LED is ON when the motor is running; and it is off, when the motor is stopped. 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 600W power levels. Higher power-levels (30V, 30A or 900W) 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 7V to 30V DC power source (unregulated) at a 0A to 20A current range to operate normally. Typical applications are: Battery Operated Water Pump Controller, Sewage Pump Controller, etc. This board can be configured and programmed to perform efficiently in many customized applications.

A Typical Application of the Si5PumpC1-30V-20A

In this application, a 24V, 500W DC motor, is turned on or off in accordance with the control requirements of the pump, as described above. 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 .
