Feature Descriptions
Remote Enable
The 9-36V ProLynx
remote On/Off operation. Two On/Off logic options are
available. In the Positive Logic On/Off option, (device
code suffix “4” – see Ordering Information), the module
turns ON during a logic High on the On/Off pin and turns
OFF during a logic Low.
On/Off option, (no device code suffix, see Ordering
Information), the module turns OFF during logic High
and ON during logic Low. The On/Off signal is always
referenced to ground.
For positive logic modules, the circuit configuration for
using the On/Off pin is shown in Figure 32. When the
external transistor Q1 is in the OFF state, the ON/OFF
pin is pulled high and transistor Q2 is OFF leading to Q3
also being OFF which turns the module ON. The
external resistor R

configuration is shown in Fig. 33. When the external
transistor Q1 is in the ON state, the ON/OFF pin is
pulled low causing transistor Q2 to be OFF and the
module to be turned ON. To turn the module OFF, Q1 is
turned OFF, causing the ON/OFF pin to be pulled high
turing Q2 ON and the module to be turned OFF.
Leaving the On/Off pin floating will leave the module in
an OFF state.

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 9-36V ProLynx modules employ an
innovative, patent pending, ‘AutoLimit’ capability. This
results in automatic scaling of current limit with output
voltage through an inverse relationship of the current
limit threshold with the output voltage. This feature
shown graphically in Fig. 34, allows higher output
currents to be drawn from the module at lower output
voltages thereby optimizing the power delivery
capability of the module.

capability at different output voltages.
Over Temperature Protection
To provide protection in a fault condition, the unit is
equipped with a thermal shutdown circuit. The unit will
shutdown if the overtemperature threshold of 130
exceeded at the thermal reference point T
thermal shutdown is not intended as a guarantee that
the unit will survive temperatures beyond its rating.
