HowTo: Replace an SSD 5401 Field Regulator
The SSD (Shackleton System Drives) 5401 Field Regulator has been obsolete for some years.
Return the units to us for repair - they can be repaired by SSD Drives repair department or by SDS Ltd in Bristol.
The modern SSD 590P Drives all have built-in Field Regulators and it will be better to replace/modernise the main drive and take advantage of the integrated FR.
The 5401 has a well designed IxR compensation circuit that is fundamental to the performance, stability and torque accuracy of some test rig drives. This is important for motors of medium to large powers and low speeds. Froude Consine and many other rolling road Dynamometers fall into this catagory.
Some new (old stock) and repaired 5401s are available from...
