The Allen-Bradley 1336-R1-SP4A snubber resistor or PC board is a spare part kit for AC drive power supplies, modules, and snubber resistor inverters. The 1336-R1-SP4A snubber resistor can be used as a replacement snubber resistor inverter for power supply modules in the 1336 FORCE, 1336 IMPACT, 1336 PLUS II and 1336 PLUS series drives. The 1336 series drives such as the 1336 FORCE, 1336 IMPACT, 1336 PLUS II, and 1336 PLUS drives are variable frequency AC drives. The output power ratings for these drive series are 0.37 to 448 kilowatts for 1336 PLUS II drives, 0.37 to 597 kilowatts for 1336 IMPACT drives, and 0.37 to 448 kilowatts for 1336 PLUS drives.
Snubber resistors like the 1336-R1-SP4A snubber resistors are designed to eliminate voltage spikes in electrical circuits that are caused by circuit inductance. These spikes occur when either a semi-conductor or a mechanical switch opens. A simple implementation of a snubber circuit consists of a capacitor and a snubber resistor in a series that are connected across a switch. The 1336-R1-SP4A snubber resistor is compatible with Frame F drives from the above mentioned Allen-Bradley AC drive product families. Each power supply module requires 3 spare part kits. The 1336-R1-SP4A snubber resistor can be used for AC drives with output power ratings including 250, 300, 250, 400, and 450 Horsepower. The 1336-R1-SP4A snubber resistor is used in AC drives with high internal voltages and currents. Only technicians familiar with Allen-Bradley 1336 AC drives should plan and implement the drive installation and servicing processes. Prior to servicing, it should be ensured that the bus capacitors have completely discharged their power. Failure to do so could lead to electric shock.
