24V 300W with 5V/0.5A Standby / MDS-300APB24 AA
Power Good
Power Good+ pin is an open collector transistor (40V/600mA
rating). A resistor (suggested value 10Kohm, 1/8W) can be added
between 5V STANDBY pin (or, other available pull-up voltage
that is no greater than 30V) and the Power Good+ pin (refer to
figure below). Value of pull-up resistor may have to be adjusted,
depending on voltage used, and other end-use conditions of the
Power Good+ pin connection to the product. When AC input is
on, Power Good+ pin will be high. When AC input is off, Power
Good+ pin will be low. There will be a minimum of 5 milliseconds
(at 240W load) between the time the power good goes to low
level, and the time when the output reaches 90% of its rated
value.
Remote On_Off/Inhibit
Remote ON_OFF/INHIBIT can be used to enable or disable only
the main output. When the main output is disabled, the +5V
Standby output will continue to operate. This signal can be pulled
down to a low level of 0.3 volts, or shorted to DC-Return, in order
for the main output to be enabled; and, floated (no connection to
the signal), or pulled up to a value greater than or equal to 3 volts,
in order to disable the main output.
Remote Sense
Remote sense feature can be used to compensate for the extra
voltage drop on output wires that are connected from the main
output terminals, to the load. With wires connected from the
remote sense pins, at the same locations as the wires from the
main output, the remote sense function can compensate up to
500mV voltage drop. The power supply will not be damaged if the
remote sense pins are shorted, or if a reverse/inverted polarity
connection is made to the load.
