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.
