Short circuit protection:There is a constant current (limit current set).

Over temperature protection:There (automatic shutdown after the shutdown)

Input back protection:No, (if required, in the input string to the diode)

Output anti - reverse protection:No,The output must add anti diodes connected to the battery, otherwise it will burn out the module! Remember!(there are reserve anti - diode location, need to be able to add their own. Methods see the following instructions

Charging indication:Bright red light when charging, full time light. Turn light detection mode for the current. In the use of solar panels, the solar hour charging current is very small, less than the light current, the same will be the green light, but this is not full, please pay attention to distinguish. For live header will more directly see the charging current.

Installation method:The 4 3mm screws

Connection mode:Terminal (when equipped with the outer casing for the welding line output)IN for the input, OUT for the output

Module size:Length 60mm width 31mm high 22mm (ecluding the header)

Weight: 44g

be carefulModule current detection for low end detection, please do not put the negative and the output of the negative electrode directly with the wire short!

Application range:

1, DIY a regulated power supply, with a constant current function, not afraid of the use of the process will be short circuit, you can protect the load.

2, power supply for your electronic equipment.

3, for a variety of battery charging, according to different voltage and capacity of the battery set charging voltage and charging current, with charging indication function, easy to observe the state of charge.

4, with the solar panel power supply for a variety of battery charging, with MPPT function, can improve the charging current more than doubled. With constant current function, can prevent the battery from charging, effectively protect the battery.

5, driving large power LED, can be freely series parallel combination,

6, as a vehicle power supply, power supply for your mobile phone or a variety of digital products.

Method for setting voltage, current, and rotating lamp: (see chart)

If the module has no output voltage, please set MPPT potentiometer clockwise to output voltage.

1, set the output voltage:With the value you want to charge the battery float voltage according to, or on, parallel LED voltage value, regulating constant potentiometer (CV), to set the output voltage to the desired voltage. (in case of no load)

2, set the lamp current indicator:After setting the output voltage, the CC potentiometer counterclockwise tune about 20 laps, with a multimeter 20A current file output short-circuit, CC regulation potentiometer to you need to turn the lamp current, and changing the lamp electric potentiometer and transferred to just the green light.

3, set a constant current value:Adjusted lamp current,20A current file is still short circuit output.Direct wire short circuit output with voltage and current meter can beAdjust the CC potentiometer to the current value you need to set. (With short-circuit and set the output current, the actual charging current than the short-circuit current is set to be small, should have residual voltage for the battery, if you want to set accurate charging current, please use after the battery connected to the output and then set the output current.

Note: the constant current setting voltage is higher than 1.25V, otherwise the constant current function will fail.

4, set the MPPT voltage value:

A, can set adjustable regulated power supply methods: adjustable regulated power supply is adjusted to the set voltage value (for eample, 18V), the output is not connected with the load, in the module has output voltage, inverse clockwise adjustment MPPT setting potentiometer to output voltage just reduce the critical point can be.

B, with the solar panel directly set the method: input directly to the solar panel, with the load to set the output voltage, covering the solar panels on the part of the light, the output of the load. The output voltage of the solar panel is measured by the universal meter, and the input voltage of the voltage meter is cut to the input voltage, and the MPPT potentiometer is adjusted to the solar panel voltage to the maimum power point voltage. (Solar panels actual maimum power point voltage will be lower than the nominal voltage, such as 18V solar panels, the maimum power point will be around 17.5V,)

Can also be used measuring the output current adjustment of MPPT value, the multimeter ammeter on output and load (with a header can be switched to the current display), callback MPPT potentiometer to the output current to a maimum value.

Note: in the use of solar panels directly MPPT value, sent by a solar panel power greater than the load power, please first Shu block according to the part on the plate is too light, in order to reduce the power of the solar panel, so as to tune quasi MPPT value.
