Press Release Summary:

August 26, 2014 - Based on MCU that can be reprogrammed for application, 3.00 x 3.00 x .85 in. PH-ET Pick and Hold modules operate on single supply from +9 to +50 Vdc and are suited for driving solenoids, valves, relays, actuators, DC motors, hydraulics, electromagnets, and LEDs. Holding current is 4 A RMS with peak (Pick) current of 15 A for high force/acceleration. Higher current and voltages are also available. Pick voltage timing and hold voltage are adjusted using onboard potentiometers.

Original Press Release

Small, Low Cost, Highly Reliable, "Pick & Hold" PWM Modules Available from OES!

Press release date: August 18, 2014

Van Nuys, CA — Optimal Engineering Systems, Inc. (OES) offers a very low cost solution for solenoid control electronics.  In Pick & Hold applications a higher (Pick) force is required initially and then a switch is made to a lower continuous (Hold) force.  This compact (3.00 in. x 3.00 in. x .85 in.) is highly efficient, PH-ET "Pick & Hold" module is easy to integrate into new and existing applications.  This module is based on a micro-controller that can easily be reprogrammed for your application. This very reliable module is ideal for driving: Solenoids, valves, relays, actuators, DC motors including voice coil and moving magnet linear motors, hydraulics, electromagnets, and LEDs.

These off-the-Shelf PWM "Pick & Hold" modules operate on a single supply voltage from +9 VDC to +50 VDC.  "Holding" current is 4 Amps RMS with a peak or "Pick" current of 15 Amps for high force and/or acceleration. Higher current and voltages are also available.

Used with an SCC-01 Solenoid Controller Card from OES up to 16 "Pick & Hold" PWM Modules can be controlled.  In each unit a Snubber Diode is incorporated to suppress voltage spikes.  PH-ET "Pick & Hold" modules accepts a TTL command voltage of 0 to 3 VDC, or 4 to 20  mAmps signals. The pick voltage timing and hold voltage are easily adjusted using onboard potentiometers, and these modules are Eco-Friendly, RoHS compliant.
