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. The user can choose between slow or fast load-current buildup/decay modes by short-circuiting or open-circuiting the pins labeled J1M. A small (2.3?x2.4?x0.45?) finned integrated heat sink is included with mounting hardware (as shown on the photograph) to operate contiuously at 20A or 600W power levels. Typical applications are: DC Motor-Speed Controller, Light-Dimmer with variable delay, Power Amplifier, SPST Solid State Relay, etc.
