CC (Constant Current): Adjusts the maximum/constant output current. Turn the potentiometers clockwise to increase and anticlockwise to decrease the corresponding setting. Use a reliable multimeter while adjusting the output voltage and current. 🔋 Battery Charger Application Determine the required battery charging voltage and charging current. Connect a suitable DC input supply to the module while observing correct polarity. Use the CV adjustment to set the required charging voltage. Use the CC adjustment to set the required charging current. Connect the battery to the output while observing correct polarity. Monitor the charging process and ensure the voltage and current remain within the battery manufacturer's specifications. 💡 Constant Current LED Driver Application Determine the LED's required operating current and maximum operating voltage. Adjust the output voltage to a low safe level before connecting the LED. Use the CC adjustment to set the required LED current. Adjust the CV setting according to the LED's required operating voltage. Connect the LED and verify the output voltage and current with a multimeter. 🛠️ Adjustment Instructions If the output voltage initially follows the input voltage and cannot be adjusted, turn the appropriate potentiometer counterclockwise for multiple turns and then adjust again. Turn the adjustment potentiometers clockwise to increase and anticlockwise to decrease. Always use a multimeter when setting voltage or current. The potentiometer closest to the output side is specified for CC/current adjustment. The potentiometer closest to the input side is specified for CV/voltage adjustment. 📦 Package Includes 1 × 10A 300W DC-DC Step-Down Adjustable Constant Voltage & Constant Current Module ⚠️ Precautions This is a step-down (buck) converter; the input voltage must be higher than the required output voltage. Do not exceed the module's maximum voltage, current, or power limits. 300W is the maximum advertised power rating; actual continuous power depends on input voltage, output voltage, current, efficiency, and cooling. For continuous high-current operation, use a cooling fan with the heatsink. Do not short-circuit the output. Observe correct input and output polarity. Use appropriate protection when charging batteries. Never leave a battery charging unattended. Ensure the module's heatsink does not become excessively hot during operation.

Out of stockNE 555 P PDIP-8 Timer IC
[Timer,Clock,Counter ICs] The NE 555 P timer IC is a precision timing circuit capable of producing accurate time delays or oscillation. In the time-delay or monostable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the as table mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor. The threshold and trigger levels normally are two-thirds and one-third, respectively, of VCC. These levels can be altered by the use of the control voltage terminal. When the trigger input falls below the trigger level, the flip-flop is set, and the output goes high. If the trigger input is above the trigger level and the threshold input is above the threshold level, the flip-flop is reset and the output is low. Features: Timing from microseconds to hours A stable or monostable operation Adjustable duty cycle TTL compatible output can sink or source up to 200mA Applications: Clock & Timing, Consumer Electronics, Aerospace, Defence, Military, Embedded Design & Development Package Includes: 1 x NE 555 P PDIP-8 Timer IC
