Item Description: Update content: 1.Fixed turn the lamp current to 0.1 times the value of the constant current(charge when used to identify whether the ... morebattery is full) 2. Increased input reverse polarity protection diode; 3. Increase the output of a backflow preventing diode to prevent when the electricity to charge the battery back in; 4. Using dedicated reference IC. And high-precision sampling resistor, so that the constant current is more stable, 20 degrees to 100 degrees, the constant current 1A, when the temperature drift of less than 1% Particularly suitable for LED driver High-power LED constant current drive Lithium battery charger(including ferroelectric) 4V. 6V, 12V, 14V, 24V battery charger Nickel cadmium. Nickel metal hydride battery pack charger Solar panels and wind turbines Specifications: Module Properties: non-isolated constant current and voltage module Rectification: non-synchronous rectification Input voltage: 7V-35V Output voltage: 1.25V-30V Output current: adjustable maximum 3A Conversion efficiency: 92% the highest) Switching frequency: 150KHz Output ripple: 50mV(max) 20M bandwidth Load Regulation: ± 0.5% Voltage Regulation: ± 2.5% Operating Temperature: 40 ℃ to +85 ℃ Size: 48* 23* 14(L* W* H) mm) Battery use: l Make sure of the voltage and current of the battery you need to charge l Adjust the constant voltage potentiometer to make the output voltage same to the charge voltage l Potentiometer Adjustment Direction: Clockwise(increase) Counterclockwise(decrease) Use the multimeter in 10A current scale to measure output short-circuit current. And adjust the current potentiometer to make sure the output current to the expected charging current value l The charge current of transfer lamp is default 0.1 times of the charging current(constant current value) l Connected to the battery and try to charging(for previous 5 steps. Module input terminal is connected to power source, output load is NOT connected to batteries) LED Constant Current Driver Use: l Make sure operating

GM328 transistor tester/ ESR table/LCR table/frequency meter/square wave generat About Description: Features: I. Overview 1 using the 2014 version of ... morethe latest V1.11 software. Using M328 chip, more features, in addition to the basic functions, as well as extensions. 2 micro-controller uses 8MHz external crystal. The measurement accuracy is better. 3 affect the accuracy of the relevant resistance using a thousandth of a metal film resistors. And the remaining one percent is also used metal film resistors. 4.LCD using 12864 LCD screen that can display measured data and graphics. 5 main chip dual in-line and with a socket. Ideal for electronics enthusiasts upgrade or replace the chip. 6 uses 9V laminated battery. 7 All components are made?of high quality genuine. LCD screen for low power backlit screen. The backlight current of about 2mA, so after boot time has backlighting for easy use in the dark. 8 Dimensions: 80(W) X 105(high) X22(depth) mm. 9 Weight: about 70 grams. The Working Current: 9V voltage. Stable operating current of about 20mA. A. The basic function 1 one-button operation. Automatic shutdown. 2 shutdown current is only about 20nA. 3.Adopt 8MH crystal. 4 can automatically detect NPN. PNP bipolar transistors, N-channel and P-channel MOS FET, JFET, diodes, dual diode, thyristor small power unidirectional and bidirectional thyristor. 5 automatic identification pin arrangement of components. Current amplification factor and base 6 measuring bipolar transistor- emitter threshold voltage. 7 can be extremely via the base- emitter threshold voltage and high-current amplification factor identification Darlington transistors. 8 protection diodes can detect bipolar transistors and MOS transistors. 9 measuring MOS FET gate threshold voltage and gate capacitance. 10. can simultaneously measure two resistors and resistor symbol is displayed. 4-digit display with decimal value 11 on the right. Resistance symbol is displayed on both sides of the pin number. So you can measure the potentiometer. If the potent
