Features: The voltmeter resolution: ±0.1V The voltmeter digital display range: 0V - 45V The voltmeter input voltage range: DC 4V - 40V Output voltage: continuous adjustable (1.3V -37V) Output current: 2A (Max 3A) Size:65 x 35mm Description: With terminal block Over-heat protection and short circuit protection function LED digital voltmeter tube, it can adjustable accurate aimed at your multimeter. Press the key "S1" to let the display show the input or output voltage. when the green led light, it shows output, the red show input. Touch the button to switch the measurement input or output voltage, and indicator light shows which voltage is being measured, it can save the settings, even if the power off and restart. Using 150KHz internal oscillation frequency, belonging to the second generation switching voltage regulator, low power consumption and high efficiency. Note: To guarantee the accuracy of the voltmeter, make sure the input voltage above 4V. The input voltage must be 1.5V higher than the output voltage or 1.5V above.

Module parameters: Scope: High-power LED constant current driver, rechargeable lithium batteries (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium nickel-metal hydride batteries (battery) charging, solar panels, wind generators Input voltage: 7-40V Output voltage: continuously adjustable (1.25-35V) (applied to the input voltage is higher than the output voltage applications can boost) Output Current: 8A, 10A maximum time within the (power tube temperature exceeds 65 degrees, please add cooling fan, 24V 12V 5A turn within generally be used at room temperature without a fan) Constant Range: 0.3-10A (adjustable) module over 65 degrees, please add fan. Turn lights Current: current value * (0.1), turn the lamp current and constant value linkage, such as constant value of 3A, turn the lamp current is set to a constant current of 0.1 times (0.1 x 3A = 0.3A), when the constant 2A, when adjusted to the current value, then turn the lamp current constant current of 0.1 times (0.1 x 2A = 0.2A). This version is a fixed 0.1 times (actually turn the lamp current value is probably not very accurate) is full of instructions for charging. Minimum pressure: 1V Conversion efficiency: up to about 95% (output voltage, the higher the efficiency) Operating frequency: 300KHZ Output Ripple: about the ripple 50mV (without noise) 20M bandwidth (for reference) Input 24V Output 12V 5A measured Operating temperature: Industrial grade (-40 ??to + 85 ?? (please note the actual use of the power tube temperature, the temperature is too high, please enhance heat dissipation) No-load current: Typical 20mA (24V switch 12V) Load regulation: ± 1% (constant) Voltage Regulation: ± 1% Constant accuracy and temperature: the actual test, the module temperature changes from 25 degrees to 60 degrees, the change is less than 5% of the current value (current value 5A) Dynamic response speed: 5% 200uS Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease) Indicator: color indicator, charging indicator light red, fully charged light green (no load is green) Output short circuit protection: Yes, constant current (constant current setting values) Input reverse polarity protection: None, Output anti-anti-perfusion: no, for charging the battery needs additional two diodes! Connection: Terminals Package included: 3 x DC-DC Step Down Adjustable Power Supply Module
