  High Power-Efficiency: 98.5% typical, at 50V and 20A

On Board:
Filter Capacitors
VTS diodes
Snubber Circuit Ready
Voltage Requirement:
A single DC Source Voltage (unregulated) with any voltage value from 9V to 50V (for Vp)

 

 Si5SD1-50V-20A Spec Sheet  (PDF)


The Si5SD1-50V-20A is a Single, 50V 20A Solenoid Driver with an integrated heat sink that uses a digital control voltage VI1,Gr (0 to 5V) to turn a load-current on or off. This board requires a single 6V to 50V DC power source (unregulated and unfiltered) at a 0A to 20A current range to operate normally with a wide range of inductive loads (coils or Solenoids). The digital control input (I1) is zener-diode protected and requires only 2mA input current (at VI1,G=5V) to turn  the load current fully on. The load current is off (zero) when 0< VI1,G<2.5V and the load current is fully on (max.) when 2.5V< VI1,G<5V. Snubbing circuits and filter capacitors are included to suppress inductive switching transients. An onboard LED (red) is used to monitor the load-voltage. A small (2.3”x2.4”x0.45”) finned integrated heat sink is included with mounting hardware (as shown on the photograph) to operate at 20A or 600W power levels. Higher power-levels (30V, 30A or 900W) can be achieved with more efficient heat-sinks. Please click on this link and read the Board Mounting Instructions and Heat Sink Selection Guide. Typical applications are: Inductive-Plunger Driver, SPST Solid State Relay, etc. This board can be configured to perform efficiently in many customized applications.

A Typical Application of the Si5SD1-50V-20A

In this application, a high-current (20A at 50V) inductive load (coil or solenoid) is turned on and off by the Digital Control Voltage VI1,G. The load current is off (zero) when 0< VI1,G <2.5V and the load current is on (max.) when 2.5V< VI1,G<5V.
