Advanced Energy CoolX600 Series
OTP condition persists for a further 2 sec, the CoolX unit will shut down. The unit
will auto-recover when temperatures reach the normal operating level.
☞
Important
On dual modules, the
OVERTEMPERATURE PROTECTION
signal is latch-
off; the signal will not auto-recover. The unit will require a reset (removal of
power for two minutes) to recover.
Shut down from the
OVERTEMPERATURE PROTECTION
signal depends on the
environment. This signal can be used to turn on an external fan or to shed loads, both
of which would reduce the temperature rise in the power supply.
☞
Important
The maximum collector voltage is 5 V, and the maximum collector current is
12 mA.

Each module has the following discrete controls:
•
“Module Enable/Inhibit”
•
“CoolMod Power Good Signal”
Module Enable/Inhibit
You can enable or inhibit each module by applying a logic level signal to the enable
input on output signal connector (J1001-J1004) pin 4 (positive) and pin 1 or pin 3
(negative). The input has a 1 kΩ series resistor and a 100 nF filtering capacitor to
filter noise on this signal. The enable and inhibit feature on dual modules works
differently; see
“Dual Module Enable/Inhibit”
on page 5

and for the dual module enable/inhibit wiring diagram.

CoolMod enable/inhibit wiring diagram
There is a maximum 15 ms turn-on delay after application of the signal. When there
is no connection, pin 4 is high (5 V) and the module is enabled.
