Output Overvoltage Protection
Output voltage overshoot may occur, if the converter is either
hot plugged-in or disconnected, the input voltage is switched
on or off, the converter is switched with an inhibit signal, or after
a reset of a short circuit and power failure. Output overvoltage
can also result due to incorrectly wired sense lines.

(in double-output models, the 2
circuitry further protects the load in the unlikely event of a
malfunction of the main control circuit.
There is no specific built-in protection against externally
applied overvoltage.
Output Current Protection
All outputs are fully protected against continuous open-circuit
condition or continuous short-circuit by an electronic current
limitation located on the primary side.
Single-output models and series- or parallel-connected
double-output models have a quasi rectangular constant
current limitation characteristic.
In double-output models, only the total current is limited,
allowing free choice of load distribution between the two
outputs, up to I
remain on both outputs to guarantee good voltage regulation.
