Feature Descriptions
Overcurrent Protection
To provide protection in an output overload fault condition,
the module is equipped with internal current-limiting circuitry,
and can endure current limiting for an unlimited duration. At
the instance of current-limit inception, the module enters a
"hiccup" mode of operation, whereby it shuts down and auto-
matically attempts to restart. While the fault condition exists,
the module will remain in this mode until the fault is cleared.
The unit operates normally once the output current is
reduced back into its specified range.
Output Overvoltage Protection
The output overvoltage protection consists of circuitry that
monitors the voltage of the output terminals. If the output volt-
age exceeds the overvoltage protection threshold, the mod-
ule enters a "hiccup" mode of operation, whereby it shuts
down and automatically attempts to restart. While the fault
condition exists, the module will remain in this hiccup mode
until the overvoltage fault is cleared.
Overtemperature Protection
The output overvoltage protection consists of circuitry that
monitors the voltage on the output terminals. If the output
voltage exceeds the overvoltage protection threshold, the
module enters a "hiccup" mode of operation, whereby it shuts
down and automatically attempts to restart. While the fault
condition exists, the module will remain in this hiccup mode
until the overvoltage fault is cleared.
Input Undervoltage Lockout
At input voltages below the input undervoltage lockout limit,
the module operation is disabled. The module will begin to
operate at an input voltage above the undervoltage lockout
turn-on threshold.
