LTC1781 100W DC/DC Step Up Converter 3-35V to 3-35V Switching Regulator Constant Current with Volt Ampere Meter USB Interface

This constant Voltage current boost module has high efficiency and little heat, low ripple and Stable performance with a digital display, can show input Voltage), output Voltage) and output current). Output with USB interface and identification resistor, a single Lithium battery can be boosted to 5V to charge your phone. It has over current protection and short circuit protection(input 15A fuse), safe to use. This is DIY a stabilized power supply, charge your electronic devices, stabilize Voltage for solar panels and etc.

• Resolution: 0.05V/0.05A (10V or less automatically switch the decimal point)

LTC1781 Features:

• Has over current protection, when the input exceeds 12A, automatically reduces the output voltage, have a range of error.
• Has Short-circuit protection, input 15A fuse, double-circuit protection.
• Output anti-anti- irrigation

LTC1781 Operational Instructions:

• Voltmeter Power Supply Selection: you can choose whether the voltmeter power supply is from input or output by jumper (IN meter is input, OUT meter is output). Relatively low voltage can decrease the voltmeter’s power consumption, it will be correct to short circuit connect jumper with a jumper cap. If you take off the jumper cap. The voltmeter will not operate.
• USB Output Port: onboard USB is for connecting with output port, if used in 3V to 5V, it can directly charge for a cellphone with recognition resistor. Please notice that when using USB for output, make sure output voltage is consistent with your digital product; otherwise, your appliance will be burned.
• Display Voltage Switch: this module can switch display input voltage and output voltage by a band switch; VI represents input voltage; VO represents output voltage.
