For standard and wide-trim modules, there are two levels of overvoltage protection
implemented on each module output: the tracking OVP level and the fixed OVP
level. Dual and bulk modules only have fixed overvoltage protection.
The tracking OVP level is relative to the set output voltage. This level turns off the
module converter if the actual output voltage exceeds the set output voltage by more
than 20%. The module recovers if the output voltage falls back within the set voltage
(this operation will be limited by the fixed OVP at high output voltages).
The fixed OVP level is fixed relative to V
max
, and activates between 125% and 160%
of the maximum output voltage. This OVP is latching and can only be reset by
completing the following steps:
1. Remove the AC.
2. Wait 2 minutes.
3. Reinstate AC power to the chassis input.

Each module has multiple levels of protection to ensure that the CoolX unit is not
damaged if used in overload conditions. Refer to the following figure:

Current and power overload characteristics
When V
set
is less than or equal to V
nom
, current limit is employed at the current limit
setpoint. However, for standard and wide-trim modules, if V
set
is greater than V
nom
,
an intelligent power limit method is employed to ensure that the module does not
exceed its power rating.
