 Si16HyPC2-30V-2x16A-1Y1  Spec Sheet  (PDF)


The Si16HyPC2-30V-2x16A is a 30V, 2x16A, 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 480W power range, and in 4W steps. An onboard microprocessor generates two 5kHz or 2.5kHz 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 jumper CN3, both 5kHz when CN3 is open and both 2.5kHz when short. 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 VI1,G and VI2,G  each providing 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. The user can choose between both slow or both fast load-current buildup/decay 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 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 2x16A or 960W power levels. Higher power-levels (30V, 2x20A or 1200W) 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 32A 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. This board can be configured and programmed to perform efficiently in many customized applications.

A Typical Application of the Si16HyUdMC2-30V-2x16A

In this application, two DC load-currents (or PWM pulse-durations) are independently and linearly adjusted by the analog inputs VI1,G and VI2,G (via, two 5KOhm Linear tapered pots SiPot2-2x5K); efficiently controlling the power to each load (or DC motor) in the 0 to 480W range in 4W 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 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.  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 www.mpja.com with the fallowing part numbers: for 33V, 10A DC output use transformer 7846-TR; for 16V, 4A DC output use transformer 7840-TR.  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.
