FEATURES DESCRIPTIONS
Output Over-Current Limit and Short Protection
The modules include internal output over-current limit (OCL) and short circuit protection (SCP) circuits, the OCL
set point is lower than that of the SCP; The response of SCP circuit is much fast than that of the OCL circuit.
The slowly increase of the output current will let module enter OCL protection when the current exceeds the
OCL set point, while the fast increase of the output current will let module enter SCP when the current exceeds
the SCP set point.
When the modules enter OCL protection, the output voltage will decrease while the output current is kept
constant, the output voltage will soft start to set point when the overload condition is removed.
The module will enter hiccup mode when it triggers the SCP set point. The module will try to restart after
shutdown. If the overload condition still exists, the module will shut down again. This restart trial will continue
until the overload condition is removed.
Output Over-Voltage Protection
The power module includes an internal output over-voltage protection(OVP) circuit, which monitors the voltage
on the output terminals. If this voltage exceeds the OVP set point, the module will shut down, and then restart
after a fixed delay time (hiccup mode), please refer to figure6 for detail.
Over-Temperature Protection
The over-temperature protection consists of circuitry that provides protection from thermal damage. If the
temperature exceeds the preset temperature threshold the module will shut down and enter into latch mode,
and all components will not exceed their absolute maximum temperature ratings.The module will not recover
until the input source is powered on again.
Remote On/Off
B62SR24015C has Enable control function. This Enable PIN is designed on the primary side of converter, the
converter will turn on when the Enable PIN connected to VIN+, and turn off when the Enable PIN connected to
VIN- or floating.

Input Reverse Voltage Protection
The input reverse voltage protection is provided by an diode on the input line, the standoff voltage for the
reverse protection shall be no less than -106V.

DESIGN CONSIDERATIONS
Parallel connection of multiple units
Two units parallel operation is verified, please contact Delta if more than two units need to be paralleled.
While parallelling multiple units, the impedance of the cables from unit to junction point of each unit should be
within ±5% of each other.

Fuse replacement
For the versions with the intergratted the fuse holder, when the fuse needs to be replaced, it can be taked down
in an anticlockwise direction by slotted type screwdrivers .

THERMAL CONSIDERATION
The following figure shows the location to monitor the temperature of base plate. Before customer decides to use
this DCDC converter, a thermal evaluation need to be done to make sure the temperature of base plate is lower
than that read from below thermal curves (Figure23~27 base on different input voltage).
