Danaher Motion / Kollmorgen PSR4 Series Power Supply with Regeneration

  • Modular Construction Maximizing Serviceability
  • Two-part Plug Connectors Interfacing Between the BDS4, PSR4/5 and Other Equipment
  • Contains a Soft Start Function and a Dynamic Bus Discharge Function
  • Diagnostic LED Indicators


The Danaher Motion / Kollmorgen PSR4 Series Power Supply with Regeneration is divided into four (4) main sections:

1. The Unregulated Logic Bus, supplied by the Control AC line input voltage (normally single-phase 115 VAC.

2. The 310/140 Main DC Bus is supplied by the main AC line input voltage (normally three-phase 230 VAC or single-phase 115VAC).

3. The Soft-Start Feature (standard) resistor limits the inrush current (to charge-up the Main Bus Capacitors).

4. The Shunt Regulator (regeneration) section includes circuitry which monitors the main bus. During deceleration profiles, the motor basically operates as a DC generator and pumps energy back into the main bus causing the bus to rise. The Shunt Regulator limits the voltage rise during the deceleration periods.

12 and 20 AMP Models: The shunt regulator (regeneration) resistor load is fuse protected. If the shunt regulator is held on for too long, the shunt regulator power transistor fails, or the shunt regulator load resistor becomes shorted, the fuse will blow and cause the Fault Contact on the PSR4 to open and the BLOWN REGEN FUSE LED to become illuminated.

The shunt regulator also includes a duty cycle limit circuit to protect against excessive load resistor heating. If the average duty cycle limit is exceeded, the regeneration circuitry will become disabled, the Fault Contact will open, and the OVERLOAD LED will become illuminated. To reset this fault, remove and reapply all input line power; bus capacitors must completely discharge.

50 and 75 AMP Models: The shunt regulator (regeneration) resistor is protected by a thermal overload relay. If the resistor rating is exceeded or if the shunt regulator transistor fails, the thermal overload output contacts will open indicating an IMMEDIATE need to remove the main power.

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
