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.
