2.2.1 Setting Output Voltage
Press the SET switch with “SET O/P VOLTAGE” selected in order to change the output voltage setting.
Pressing the UP switch will increment the output voltage by 0.1V. Pressing the DOWN switch will decrement
the output voltage by 0.1V. The output voltage setting range for 12V units is 10.5 – 14V, with a default value
of 13V. The output voltage setting for 24V units is 21 – 28V, with a default value of 26V. Pressing the BACK
switch will store the value in memory return to the configuration menu.
2.2.2 Setting Current Limit
Press the SET switch with “SET CURR. LIMIT” selected in order to change the maximum charging current of the
RHF battery charger.
Pressing the UP switch will increment the current limit by 1%. Pressing the DOWN switch will decrement the
current limit by 1%. The range for the battery current limit is 50 – 105%. The default value is 100%. Please
consult the battery manufacturer for the maximum charging current of the connected batteries. Pressing the
BACK switch will store the value in memory and return to the configuration menu.
2.2.3 AC Mains Voltage
Press the SET switch with “MAINS VOLTAGE” selected in order to view the Voltage from the AC mains. The
Mains Voltage is not a setting; it is simply a way to view the AC Voltage present to the RHF. Press BACK to
return to the configuration menu.
2.2.4 Thermal Derating
Press the SET switch with “THERM.DERATING” selected in order to enable/disable Thermal Derating. The
asterisk (*) on the display indicates the current setting. When enabled, the unit will monitor the rectifier’s
temperature. If the ambient temperature exceeds 50°C, it will lower the current limit to 70% in order to
prevent the charger from overheating. When the ambient temperature returns below 50°C, the current limit
will return to the previously set value.
Additionally, all chargers are equipped with a thermal shutdown function; which cannot be disabled. If the
ambient temperature exceeds 70°C, the DC output will shut off. The charger will continue to monitor the
ambient temperature. When the temperature returns to a safe level of 40°C the output will be restored.
