Overcurrent Protection
the unit is equipped with internal current limiting circuitry and
can endure current limiting for an unlimited duration. At the
point of current-limit inception, the unit shifts from voltage
control to current control. The unit operates normally once the
output current is brought back into its specified range.
Input Source Impedance
ac-impedance input source. Highly inductive source
impedances can affect the stability of the power module.
output loading is high, it may be necessary to use a capacitor
at the input to ensure startup.
ensure stability of the unit, it is recommended to use a good
quality low Equivalent Series Resistance (ESR < 1.0[ at 100
KHz) capacitor of a 6.8uF for the 24V and 48V devices
To provide protection in a fault (output overload) condition,
