Penta drive ac motor speed control adj. frequency drive
Input: 115/208-230 VAC-50/60 Hz
Output: 0-230 VAC, 0-50,60/100, 120 Hz
Washdown and Watertight for Indoor and Outdoor Use
* Motor Overload Protection - Provides motor overload protection which prevents motor burnout and eliminates nuisance trips.
* Power Start - Provides more than 200% starting torque and ensures startup of high frictional loads.
* Electronic Inrush Current Limit - Eliminates harmful inrush AC line current during startup.
* Dual Voltage Input - The control operates from 115 or 208/230 Volt 50/60 Hz single phase AC line input.
* Horsepower Selection - The control contains a horsepower selection jumper which eliminates the need to recalibrate the CL trimpot for different motors.
* Short Circuit Protection - Shuts down the control if a short circuit occurs at the motor (phase-to-phase).
* Regeneration Protection - Eliminates tripping due to bus overvoltage caused by rapid deceleration of high inertial loads.
* Slip compensation with Boost - Provides excellent load regulation over a wide speed range.
* Start/Stop Switch - Provides electronic start and stop.
* Ride-Through - Provides smooth recovery to the previous set speed during a momentary power loss.
* Diagnostic LEDs - Power on (Power) and control status (Status).
* Barrier Terminal Block - Facilitates wiring of motor and AC line.
* Protection Features - Undervoltage and overvoltage protection. MOV input transient protection. Microcontroller self-monitoring and auto reboot. Short circuit protected phase-to-phase at motor.
* Holding Torque at Zero Speed - Resists motor shaft rotation when the control is in stop mode.
This has never been used. I bought this a while ago and it has been stored on a shelf ever since.
