The Si5HyPC2-30V-2x16A  is a microprocessor based, Dual, 30V at 2x16A Power-Controller with an integrated heat sink. This board uses two independent pulse-width modulators (PWM) to efficiently control the power-transfer for two inductive  loads, each in the 0 to 480W power range with 4W steps. An onboard microprocessor generates two 5kHz or 20kHz PWM carrier signals, controls the load-current to each load  and controls the current buildup and decay rate  of each load. 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 current control to each load and insures a flicker-free load environment. As the name hybrid (Hy) implies, the desired load currents (or PWM pulse-durations) are set by two variable (0 to +5V) analog input-voltages VI1,G and VI2,G  each providing a smooth current control from 0 to 100% in 0.83% steps; while the other control-signals are digital. These analog inputs (VI1,G and VI2,G) are zener-diode protected and each includes an integrator with a time-constant of 0.01s; accordingly, each input can be driven with DC or PWM signals. The user can choose between both slow or both fast load-current acceleration/deceleration modes by short-circuiting or open-circuiting the pins labeled J1.  The slow mode, with rise-time/fall-time of 0.5s, is selected by short-circuit (J1 jumper installed); while the fast mode, with rise-time/fall-time of 0.025s, is selected by leaving these pins open (no Jumper installed). Two onboard LEDs (red) are used to monitor the load-voltages. Two sets of snubbing circuits and filter capacitors (one for each load) are included to suppress load-current switching transients. A small (2.3”x2.4”x0.95”) finned  integrated heat sink is included with mounting hardware (as shown on the photograph) to operate at 2x16A or 960W power levels. Higher power-levels (30V, 2x30A or 1800W) can be achieved with more efficient heat-sinks. This board requires a single 9V to 30V DC power source (unregulated ) at a 0A to 32A current range to operate normally. Typical applications are: Dual DC Motor-Speed Controller, Dual Light-Dimmer with variable delay, Dual Power Amplifier, Dual SPST Solid State Relay, etc. This board can be configured and programmed to perform efficiently in many customized applications.

 A Typical Application of the Si5HyPC2-30V-2x16A

In this application, two load-currents (or PWM pulse-durations) are and linearly adjusted by the analog inputs VI1,G and VI2,G (via, two 5KOhm Linear tapered pots, Si5Pot2-2x5k )  independently controlling the power to each load in the 0 to 480W range in 4W steps.  

An inexpensive, unregulated DC power supply design is shown in this application drawing. This power supply consists of a transformer, a 40A bridge rectifier and an optional C=2200uF, 35V capacitor ( part number 493-1323-ND).  The secondary voltage and current rating of the transformer determines the DC voltage and current output of this power supply. Low-current output transformers can be purchased from with the fallowing part numbers: for 33V, 10A DC output use transformer 7846-TR; for 16V, 4A DC output use transformer 7840-TR. The component cost of this low-current output power supply is under $20. A wide variety of linear and switching power supplies can also be used with this board. Consult the most recent catalog on to purchase these power supplies.  Warning:  The connecting wires to the Motor and the Power Supply must be heavy gage copper wire (#12 AWG or heavier) to handle the rated current level. In addition, these heavy gage wires act as a heat sink, protecting the board from overheating.
