3.7.2 Softstart & Power Cycling Frequency Limits

The DS2100 contain an internal soft-start function. The soft-start function limits the inrush current into the DS2100's
D.C. Bus smoothing capacitors after the a.c. mains has been switched on.

If the frequency of power cycling becomes too high, then the power dissipation in the soft-start resistor can be excessive.
In this case the softstart circuitry may become damaged.

CAUTION:- The internal softstart resistors are designed to allow an AC application of
once every 60 seconds. If this rate is exceeded, then the internal softstart resistors may
be damaged.
