The PMDX-137 is a legacy product that is no longer in production and no stock is available.

The PMDX-137 is a power preparation module for use with CNC motor drivers

• Offered in 80 volt and 50 volt versions
• Supplies up to 20 Amperes of filtered, unregulated DC when connected to a suitable input transformer
• Includes electronic load "DUMP" to help prevent overvoltage when motors produce "back EMF" during rapid deceleration
• Dump circuit provides rapid power off discharge of storage capacitors (under 5 seconds) for additional user safety
• Provides connection for external "dump" resistor when needed for servo systems with significant amounts of returned energy from decelerating servo motors
• Has multiple DC output terminals for easier wiring of multiple wires to drivers
• Utilizes multiple filter capacitors in order to better handle ripple current heating effects
• Utilizes heavy duty bridge rectifier mounted to a large heatsink
• Indicators furnished for "DC Output ON" and back EMF "DUMP"
• Ideal power source for our PMDX-132, 133, and 133 motherboards for Geckodrive stepper motor drivers
• Can be used to power all models of Geckodrive stepper and servo motor drivers and also drivers from many other vendors
• Has enough power capability to run 4 Geckodrive stepper motor drivers at full power
• The PMDX-137 is a functional replacement for the obsolete PMDX-135. It is in a more compact mechanical form and will not directly mount to the same holes as a PMDX-135.

** Geckodrive, Inc. the maker of the Gecko motor drivers does not manufacture, sell, or provide techincal support for the PMDX-137.
