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 6A modules feature an On/Off pin with positive
logic for remote On/Off operation. If the On/Off pin is not being
used, 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 (VOn/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 average
output current during hiccup is 10% IO, max.
Overtemperature Protection
To provide protection in a fault condition, these modules are
equipped with a thermal shutdown circuit. The unit will shut down
if the overtemperature threshold of 130ºC is exceeded at the
thermal reference point Tref. 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, the
module operation is disabled. The module will begin to operate at
an input voltage above the undervoltage lockout turn-on
threshold.

Output Voltage Programming
The output voltage of the Naos Raptor 6A module can be
programmed to any voltage from 0.59dc to 6Vdc by connecting a
resistor between the Trim+ and GND pins of the module. Certain
restrictions apply on the output voltage set point depending on the
input voltage. These are shown in the Output Voltage vs. Input
