3.7.2 Softstart & Power Cycling Frequency Limits
The DS2110 contains an internal soft-start function. The soft-start function limits the inrush current into the
DS2110'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.
