2.2.1 NOTES

2.2.1.1 The HP listing is for reference only. For proper selection use the current rating.

2.2.1.2 The fuses recommended are Class J time-delay type. This fuse is being

suggested even though it may not protect the SCR in an output shorted
condition while braking. It will protect the unit  when starting to operate into a
shorted output. In the case of a shorted SCR, the fuse is there to clear the fault
only.

2.2.1.3 The RMS AC line current is equal to :     AC RMS = DC Amps x 

√ 

Duty Cycle

Assuming 10A motor, TRU-START DC Injection set at 300% current (30 A DC), 
free wheeling for 70% of the cycle,  then the  AC current is 16A.

2.2.1.4

 

All TRU-START DC Injection models are built without cooling fans because they 
are short duty rated.
