OVL - Overvoltage Cutoff Limit
HexCode: 02
Description:
Sets the voltage level at which the controller must turn off its power stage and signal an
Overvoltage condition. Value is in volts multiplied by 10 (e.g. 450 = 45.0V) . The power
stage will turn back on when voltage dips below the Overvoltage Clearing threshold that
is set with the the OVH configuration command.
Syntax Serial: ^OVL nn
~OVL
Syntax Scripting: setconfig(_OVL, nn)
Number of Arguments: 1
Argument 1: Voltage
Type: Unsigned 16-bit
Min: 100 = 10.0V Max: See Product Datasheet
Default: See Product Datasheet
Where:
nn = Volts *10
Example:
^OVL 400 : Set Overvoltage limit to 40.0V
Note:
On firmware versions 1.5 and earlier, no hysteresis exists and the overvoltage condition is
cleared as soon as the voltage dips below the overvoltage limit.
OTL - Over Temperature Cutoff Limit
HexCode: D1
Description:
Sets the Heatsink Temperature level at which the controller must turn off its power stage
and signal an OverHeat condition. Value is in Celsius degrees . When temperature reaches
10 degrees below the limit, the controller starts to decrease the maximum applied power
(duty cycle), by 10% for each additional degree. The power stage will turn back on gradu-
ally when heat sink temperature dips below the above limit. See Section 7, chapter “Tem-
perature-Based Protection” for more details.
Syntax Scripting: setconfig(_OTL, nn)
Number of Arguments: 1
Argument 1: Temperature Type: Unsigned 16-bit Min: 0 Max: 85
Where:
nn = Temperature in Celsius degrees
