Do not test this power supply with a laboratory 3A adjustable voltage regulator.

The maximum voltage regulation rate under high output voltage (80V) current is -3%. If there are high requirements, continuous mode can be selected within -1%.\u003cbr\u003e2: Direct mode is to set a voltage range that allows input and output to pass through. If the input is below this range, boost operation will be carried out, and if it is above it, buck operation will be carried out (for example, if the input is 20-80V and the direct voltage is 40-50V, then the efficiency of input 40-50 through is high, if the input is 20V-40V, boost and stabilize to 40V, and if the input is 50-80V, buck and stabilize to 50V)\u003cbr\u003e3: The ripple of the boost output capacitor is large, and the ripple of the buck input capacitor is large, which reduces heat generation and prolongs life. More electrolytic capacitors can be connected in parallel.\u003cbr\u003e4: The default intermittent working mode is required for direct battery charging, otherwise it is recommended to add an ideal diode to the output.\u003cbr\u003e5: The situation where the startup time needs to be adjusted is when the input source startup time is relatively long, such as when the AC adaptation output full load voltage establishment time is 50ms, while the startup time of this power supply is 15ms, which may cause abnormal operation.\u003cbr\u003e6: Some parameters may be adjusted for different applications.\u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"width: 1000px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/106072\/106072-01.jpg\"\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eInterface Introduction:\u003c\/b\u003e\u003cbr\u003e- VIN+: Power input positive pole; INPUT+.

When the input power is insufficient and the input voltage drops, the automatic clamp will set the voltage and automatically reduce the output current. Suitable for fuel cell, solar panel, and generator input applications. For example, if the maximum power voltage of the solar panel is 36V, input 36V and adjust RX1 clockwise until Ied2 just lights up. If the forced input is below 36V, there will be no output.\u003cbr\u003e- RX2: Output current regulation, increasing clockwise; 25 rotations of the potentiometer correspond to a change in output current of 0-20A. If the potentiometer is damaged or open circuited, the output current limit value will be 10A.\u003cbr\u003e- RX3: Adjust the output voltage clockwise to increase the output voltage. In normal working mode, RX2 adjusts the output voltage value. If the potentiometer is damaged or open circuit occurs, the output voltage will be 48V.\u003cbr\u003e- RSE: Output current sampling resistor. 3mΩ resistor, Iout=Vr\/0.003.

Negative pole connected to control signal.\u003cbr\u003e- P2-2: EN enable port; If the PIN is pulled down to GND, the power is turned off, the standby current is at uA level. If remote control is required, it is recommended to add optocoupler isolation (line length is susceptible to interference).\u003cbr\u003e- P2-3: Output voltage control interface. A rising edge time of at least 20ms must be given. Instant high-frequency control is not allowed. The interface controls the output voltage from 0-94V by connecting the GND signal voltage to 0-2.1V. The signal must not be negative, RX2 needs to be counterclockwise to the end before use.\u003cbr\u003e- P2-4: Output current control interface. A rising edge time of at least 20ms must be given.

It is recommended to use the CR mode. CC mode absorbs current, this power supply has current limit, and in a constant current state, it will cause the power supply to crash.\u003cbr\u003e6: Suggest adjusting the output voltage to connect a small current resistor load (false load) to ensure real-time adjustment of the output voltage potentiometer, otherwise the output voltage changes slowly; The adjustment value is not accurate.\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Included:\u003c\/b\u003e\u003cbr\u003e- 1 x Power Module\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(255, 42, 0);\"\u003e\u003cstrong\u003eOptional Acc:\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- 1 x Heat Sink \u003cspan style=\"color: rgb(43, 0, 255);\"\u003e(Optional)\u003c\/span\u003e\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- 1 x Cooling Fan \u003cspan style=\"color: rgb(43, 0, 255);\"\u003e(Optional)\u003c\/span\u003e\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- 1 x Voltage\u0026amp;Current Display Module \u003cspan style=\"color: rgb(43, 0, 255);\"\u003e(Optional)\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"width: 1000px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/106072\/106072-02.jpg\"\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Thanksbuyer","offers":[{"title":"Power Module","offer_id":41322808868913,"sku":"106072","price":78.95,"currency_code":"USD","in_stock":true},{"title":"Power Module + Heat Sink","offer_id":41322808901681,"sku":"106073","price":80.5,"currency_code":"USD","in_stock":true},{"title":"Power Module + Cooling Fan","offer_id":41322808934449,"sku":"106074","price":80.5,"currency_code":"USD","in_stock":true},{"title":"Power Module + Voltage\u0026Current Display Module","offer_id":41322808967217,"sku":"106075","price":86.72,"currency_code":"USD","in_stock":true},{"title":"Power Module + Heat Sink + Cooling Fan + Voltage\u0026Current Display Module","offer_id":41322808999985,"sku":"106076","price":90.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0578\/4790\/6353\/files\/20261103175745_71486576.jpg?v=1793776024"}],"url":"https:\/\/www.thanksbuyer.com\/it\/collections\/power-supply-module.oembed","provider":"Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products,  Audio Amplifer and Decoders","version":"1.0","type":"link"}
