Overvoltage
protection
1 V to 22 V 1 V to 66 V 1 V to 22 V 1 V to 66 V
Remote sensing capability Voltage drop Up to 1 V per each lead
Load regulation Add 5 mV to specification for each 1 V change in the + output lead due
to load current changes.
Load voltage Subtract the voltage drop in the load leads from the specified output
voltage rating.
