Safety Considerations
For safety agency approval the power module must
be installed in compliance with the spacing and
separation requirements of the end-use safety agency
standards, i.e., UL 60950-1, CSA C22.2 No. 60950-1-
03, and VDE 0850:2001-12 (EN60950-1) Licensed.
For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV), the
input must meet SELV requirements. The power
module has extra-low voltage (ELV) outputs when all
inputs are ELV.
An input fuse for the module is recommended. Due to
the wide input voltage and output voltage ranges of
the module, different fuse ratings are recommended
as shown in Table 1. These are suggested
“maximum” fuse ratings. However, for optimum circuit
protection, the fuse value should not be any larger
than required in the end application. As an option to
using a fuse, no fuse is required, if the module is
1. powered by a power source with current limit
protection set point less than the protection
device value listed in Table 1, and
2. the module is evaluated in the end-use
equipment.

Feature Descriptions
Remote On/Off
The Naos Raptor 60A power modules feature a
remote On/Off pin with positive logic. If not using the
On/Off pin, leave the pin open (the module will be ON,
except for the -49 option modules where leaving the
pin open will cause the module to remain OFF). The
On/Off signal (V
On/Off
) is referenced to ground.
During a Logic High on the On/Off pin, the module
remains ON. During Logic-Low, the module is turned
OFF.

Overcurrent Protection
To provide protection in a fault (output overload)
condition, the unit is equipped with internal
current-limiting circuitry and can endure current
limiting continuously. At the point of current-limit
inception, the unit enters hiccup mode. The unit
operates normally once the output current is brought
back into its specified range. The typical average
output current during hiccup is 10% of I
o,max
.
Over Temperature Protection
To provide protection in a fault condition, the unit is
equipped with a thermal shutdown circuit. The unit will
shut down if the overtemperature threshold of 135ºC
is exceeded at the thermal reference point T
red
. The
thermal shutdown is not intended as a guarantee that
the unit will survive temperatures beyond its rating.
Once the unit goes into thermal shutdown, it will then
wait to cool before attempting to restart.
Input Undervoltage Lockout
At input voltages below the input undervoltage lockout
limit, module operation is disabled. The module will
begin to operate at an input voltage above the
undervoltage lockout turn-on threshold.
