1394 External Shunt Kit and Modules

Shunt modules dissipate excess regenerative power from the Bulletin 1394 system. An external shunt

resistor kit (1394-SR10A) is available for 5 and 10 kW systems with regenerative loads that exceed the

capacity of the internal 200W shunt resistor provided. Most 5 and 10 kW systems will not require an

external shunt resistor kit.

All 22 kW 1394 system modules require an external shunt module (1394-SR9Ax or 1394-SR36Ax). Shunt

modules with (rms) power output of 300, 900, 1800 and 3600W continuous, 160,000W peak are available

for use with the smart power 22 kW system module. You must use one shunt module with each 22 kW

smart power system module. Available in two sizes, each package contains an integral fuse and terminal

block. The 3600W package is available with a 115/230V AC cooling fan. Choose your shunt module based

on the shunt requirements of the 1326Ax-Bxxxx servo motors you plan to run using the 1394.
