Feature Descriptions
Remote On/Off
The EQD020 series power modules have primary
referenced remote On/Off. The remote on/off is open
collector compatible with the signal common
referenced to the negative input. The standard
remote on/off negative logic is such that a unit
operates (ON) when the remote on/off signal is low or
short circuit to minus VIN. A module will be OFF when
the remote on/off pin is open circuit or when the
remote on/off signal is high. Observe the maximum
external ON/OFF voltage, specified in the Feature
Specifications table, when connecting an external
source to the ON/OFF pin. The optional positive logic
remote on/off is such that a unit operates (ON) when
the remote on/off signal is high or open-circuit. A unit
will be OFF when the remote on/off signal is low or
short-circuited to minus VIN.

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 a hiccup mode. If the unit is
not configured with auto–restart, then it will latch off
following the over current condition. The module can
be restarted by cycling the dc input power for at least
one second or by toggling the remote on/off signal for
at least one second. If the unit is configured with the
auto-restart option (4), it will remain in the hiccup
mode as long as the overcurrent condition exists; it
operates normally, once the output current is brought
back into its specified range.
Input Under Voltage Lockout
At input voltages below the input under voltage
lockout limit, the module operation is disabled. The
module will begin to operate at an input voltage above
the under voltage lockout turn-on threshold.
Over Temperature Protection
These modules feature an overtemperature protection
circuit to safeguard against thermal damage. The
circuit shuts down and latches off the module when
the maximum device reference temperature is
exceeded. The module can be restarted by cycling
the dc input power for at least one second or by
toggling the remote on/off signal for at least one
second. If the auto-restart option (4) is ordered, the
module will automatically restart upon cool-down to a
safe temperature.
Output Over Voltage Protection
The output over voltage protection scheme of the
modules has an independent over voltage loop to
prevent single point of failure. This protection feature
latches in the event of over voltage across the output.
Cycling the on/off pin or input voltage resets the
latching protection feature. If the auto-restart option
(4) is ordered, the module will automatically restart
upon an internally programmed time elapsing.
Remote sense
The EQD020 series power modules have a Remote
Sense feature to minimize the effects of distribution
losses by regulating the voltage at the Remote Sense
pin (See Figure 20). The voltage between the Sense
pin and Vo pin must not exceed 0.33V.
The amount of power delivered by the module is
defined as the output voltage multiplied by the output
current (Vo x Io). When using Remote Sense, the
output voltage of the module can increase, which, if
the same output is maintained, increases the power
output from the module. Make sure that the maximum
output power of the module remains at or below the
maximum rated power. When the Remote Sense
feature is not being used, connect the Remote Sense
pins to the output pins of the module.
