Si14HyATPC1-50V-20A The Si14HyATPC1-50V-20A is a single, microprocessor based, Hybrid, Adjustable Ramp-Time, Power-Controller board (DC dimmer) that uses 20kHz pulse-width modulation (PWM) to efficiently control the power flow (or DC load-current) to an inductive load, from 0 to 1000W in 8.33W steps. The load-current build-up/decay time is adjustable (using the Ramp-Time input) from 100ms to 25.5s in 100ms steps. An optional 2 line by 20 characters long LCD (with HITACHI HD44780 Interface Standard) is used for Set-PWM Measured-PWM and Ram-Time data display.

Si5HyPC1-30V-20A The Si5HyPC1-30V-20A is a single, 30V at 20A, Hybrid, Open-Loop, Power Controller with an interated heat sink. This board uses: one Analog Control Input (0 to 5V) for Set-PWM adjustment; one 20A MOSFET Output (with 9 to 30V DC source voltage). This output is Pulse-Width Modulated (PWM) at 5kHz or 20kHz rate, efficiently controlling the power flow to an isolated DC Load (or Motor) from 0 to 600W in 5.0W steps.

Si5HyPC2-30V-2x16A The Si5HyPC2-30V-2x16A is a dual,30V at 2x16A, Hybrid, Power Controller with an integrated heat sink. This board uses two independent Analog Inputs (0 to 5V) for PWM adjustments; two 16A MOSFET Outputs (with 9 to 30V DC source voltage); two independent 5kHz or 20kHz Pulse-Width Modulators (PWM), efficiently controlling the power flow to two isolated DC Loads (or Motors), each from 0 to 480W in 4W steps. The user can choose between both slow or both fast load-current build-up/decay modes by short-circuiting or open-circuiting the pins labeled J1M.

DC Pump Controller
Si5PumpC1-30V-20A Si5PumpC1-50V-20A is a 30V 20A microprocessor based pump controller with an integrated heat sink that 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 (user selectable) mechanical float-switch is used to stop the motor rotation whenever the fluid tank is full. This switch 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. 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.

H-Bridge
Si20HPB4-50V-20A The Si20HPB4-50V-20A is an efficient high-power H-bridge board that works over a wide range of source voltages (9V to 50V) at high continuous load currents (+/-20A max) when mounted on a 6” by 6” metal plate. Higher current values can be attained with more efficient heat sinks. The motor action (as shown on the truth table below) is controlled by the voltages applied to pin F and pin R (relative to pin C) on the Control connector These pins are optically isolated from the rest of the power circuit, requiring a minimum input current of 1.5 mA at 3.5V and max input current of 7mA at approx. 9V.
