1pcs DC-DC Auto step-up/down constant voltage/current power supply module Description Advantage: Large heat sink to ensure the strong heat; Jumbo 1.6 boards, increase the stability; Three lines 0.6 and around Kool toroid inductors, easy saturation; further reduce heat loss; Four power tubes, full of material; Using high-frequency low-impedance input and output capacitance, making the output ripple is very small; On-board DIP switch, turns off reduces the quiescent current. Module Parameters: Module Properties: non-isolated synchronous rectifier buck module automatically Input voltage: DC5-30V Input current: 8A (MAX) peak 10A (6A work for a long time) Quiescent current: 4mA (not both be working voltage error) The output voltage :1.25-30V continuously adjustable (the default output 12V, For other voltages, please note when photographed.) Output Current: 10A (MAX) (5A long natural cooling inside) For higher output current, two modules can be used in parallel, such as the output to 10A, can be connected in parallel with two modules, each module is transferred to the current 5A can. Output current range :0.2-10A (default 4A delivery, such as the need for other voltages, please note when photographed) Working temperature: -40 ~ +85 degree Operating Frequency: 150KHz Conversion Efficiency: 91% (12V turn 12V5A) highest 93% Overcurrent protection: Yes Short-circuit protection: Yes (limiting protection Over-temperature protection: (automatically reduces the output voltage over temperature) Input Reverse Polarity Protection: No, (if necessary, please enter the string into the diode) Output anti-anti-irrigation: Yes, no need for charging plus blocking diode. Wiring: screw terminal output, (IN is the input, OUT is the output) Module size: 60mm * 53mm * 20mm (LxWxH) Applications: This module can be applied to relatively large fluctuations input voltage, output requirements are relatively stable areas. Such as: . 1 12V battery (10-14V) voltage output 12V, 12V equipment to power, 24V battery voltage 24V; may use as a vehicle power supply, drive 12V books and so on. 2 solar panel regulator voltage fluctuations, relatively large solar panels, this module can be regulated output power to the device or to charge the battery to use. 3. Driving power LED lights, constant current drive, such as 12V battery drive four LED lights, this time the LED and battery voltage less. shipping list:1pcs DC-DC Auto step-up/down constant voltage/current power supply module Payment We accept Paypal as the payment method.
