Notes:
1. Limited power percentage of voltage control：
When battery voltage changes, the actual operating power is limited, which is a linear increase or decrease. It operates as
per the following formula:
Actual operating power% = [(Battery voltage-11.1V)/(12.0-11.1V)]*(setting power% of current timer section - limited
power%)+limited power %.
Notes: When it is powered for the first time, the system identifies the voltage＜18V as 12V system, and ≥18V as 24V
system. The above formula is applicable for 12V system. If it is 24V system, 11.1v is changed into 22.2V and 12.0V into
24.0V in the formula. When the battery voltage is lower than 11.1V or 22.2V, the formula is not applicable and the actual
power is operated as per the limited power. And when the battery voltage is higher than 12V or 24V, the actual power is
operated as per the setting power of current timer.
2. Limited power percentage of temperature control:
The control theory for temperature change is the same as voltage change, with the formula changed into the following:
Actual operating power% = [(current temperature-75℃)/(85℃-75℃)]*(setting power% of current timer section - limited
power%)+limited power %.
Notes: The effective temperature range is 75℃~85℃. When it is lower than 75℃, the actual power is operated as per the
setting power of current timer section. And when it is higher than 85℃, it is operated as per the limited power.
3. If the limited power percentage of voltage control or temperature control is more than current timer section, or there
is no power percentage limitation of voltage and temperature, it operates as per the power of the current timer.
4. When percentage limitations of voltage and temperature work at the same time, the actual power operates as per the
min. power calculated with the above formulas.
5. There is a period of 2-20 seconds for power adjustment each time, so it is not realized at once. The frequency of
PWM is 200Hz.
