The Si16HyPC2-S13kHz-30V-2x6A is a 30V, 2x6A, microprocessor based, Dual, Hybrid, Power Controller with common ground and with an integrated heat sink. By common ground we mean that the negative load terminals (-L1, -L2) are internally connected to the negative terminal of the power source (-P) and can be tied to the chassis ground. This board uses two independent pulse-width modulators (PWM) to efficiently control the power flow (or DC currents) in two inductive loads each in the 0 to 180W power range, and in 1.5W steps. An onboard microprocessor generates the PWM carrier signals, controls the load-power to each load and controls the load-current buildup and decay rates. The PWM carrier frequency is user selectable by the jumperJ1 and J2 as shown below. The high frequency PWM rate provides a smooth DC current control to each load and insures a quiet 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 V_I1,G and V_I2,G  each providing control from 0 to 100% in 0.83% steps; while the other control-signals are digital. These analog inputs (V_I1,G and V_I2,G) are zener-diode protected. The user can choose between both slow or both fast load-current buildup/decay modes by short-circuiting or open-circuiting the pins labeled CN3. The slow mode, with rise-time/fall-time of 0.5s, is selected when CN3 jumper is installed (CN3 is short); while the fast mode, with rise-time/fall-time of 0.025s, is selected by leaving CN3 open (no Jumper installed). Two onboard LEDs (red for channel 1, green for channel 2) are used to monitor the load-voltages. Snubbing circuits and filter capacitors are included to suppress inductive 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 2x6A or 360W power levels. Higher power-levels (30V, 2x10A or 600W) can be achieved with more efficient heat-sinks. This board requires a single 9V to 30V DC power source (unregulated and unfiltered) at a 0A to 12A current range to operate normally.Typical applications are: Dual Power Controller, Dual Light-Dimmer with variable delay, Dual Power Amplifier, Dual SPST Solid State Relay, etc. 

Specification and Application for Si16HyPC2-S13kHz-30V-2x6A

A Typical Application of the Si16HyPC2-S13kHz-30V-2x6A

In this application, two DC load-currents (or PWM pulse-durations) are independently and linearly adjusted by the analog inputs V_I1,G and V_I2,G (via, two 5KOhm Linear tapered pots SiPot2-2x5K); efficiently controlling the power to each load (or DC motor) in the 0 to 180W range in 1.5W steps. 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. An inexpensive, unregulated DC power supply is shown below. A wide variety of linear and switching power supplies can also be used with this board. Consult the most recent catalog on www.mpja.com to purchase these power supplies. Warning:  The connecting wires to the Motor and the Power Supply must be heavy gauge copper wire (#12 AWG or heavier) to handle the rated current level. In addition, these heavy gauge wires act as a heat sink, protecting the board from overheating.
