LED Driver Controller LDC-01
—For DCCP series LED driver
Thank you for selecting the product. LDC-01(LED Driver Controller) is an optional accessory for DCCP series LED DC
driver. It can realize max. 4 -timer working. For each timer, 0~9 working hours and 0~100% output power is adjustable.
The output power can also be adjusted automatically with changes of battery voltage and temperature. Read this manual
carefully and thoroughly so as to preferably install and use the product. Under normal service conditions, the warranty
period of the product is two (2) years free of charge, starting from the sales date.
Introductions:
As shown in above picture:
Input terminals: connect controller or other DC power supply.
Output terminals: connect DCCP series LED driver. PWM frequency is 200Hz.
Button: Set the working hours and power percentage.
Display bar: Display the timer and power percentage.
Temperature sensor: fit to the heat sink of LED source.
Functions:
Operations:
1. Under non-setting state, press the button lightly, LED indicators are lighted circularly each time,
2. Press the button for more than 5 seconds till the LED indicator flashing. Release it at this moment. Then press the
button to choose the desired number.
3. Under the setting state, if the desired number appears, stop pressing the button. When the LED indicator stops
flashing, the setting is successfully.
4. If there is no any button pressing within 15 seconds, the LED indicator and digital tube will be turned off
automatically for power saving.

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. Parameters:
