Règleman Retou & Echanj
Nou sèlman aksepte atik ki achte nan roymall.com. Si ou achte nan distribitè lokal nou yo oswa lòt revandè, ou pa ka retounen yo sou bò pa nou. Atik lavant final oswa kado gratis pa akseptab pou retou.Pou kalifye pou yon retou, atik ou a dwe itilize epi nan menm kondisyon ke ou te resevwa li. Li dwe tou nan anbalaj orijinal la.Apre ou fin resevwa enstriksyon retou nan men nou, tanpri anbalaje atik ou retounen yo epi depoze pake ou a nan biwo lapòs lokal la oswa yon lòt kurye.Nou pral trete retou ou a oswa atik echanj nan 3-5 jou ouvrab apre nou fin resevwa li. Rembousman an pral trete epi kredite otomatikman nan metòd orijinal ou pou peman.Pa gen retou oswa echanj ka aksepte si pwodwi a te pwodui pèsonalize, ki gen ladan gwosè pèsonalize, koulè pèsonalize, oswa enprime pèsonalize.Bezwen plis èd, tanpri kontakte nou. service@roymall.com oswa Whatsapp: +8619359849471
2.Règleman Rembousman
Ou pral jwenn yon rembousman konplè oswa 100% kredi nan magazen apre nou fin resevwa pake retounen an epi verifye li. Rembousman an pral trete epi kredite otomatikman nan metòd orijinal ou pou peman.Tanpri sonje ke depans livrezon ak nenpòt dwa oswa frè pa rembousab. Depans livrezon siplemantè yo pa rembousab yon fwa pake a te anvwaye. Ou responsab pou peye frè sa yo epi nou pa ka egzante oswa rembouse yo, menm si lòd la retounen ban nou.Apre nou fin resevwa epi konfime atik ou retounen an, nou pral voye yon imèl ba ou pou fè ou konnen nou te resevwa atik ou retounen an. Nou pral tou fè ou konnen apwobasyon oswa rejè rembousman ou.Si ou gen nenpòt pwoblèm konsènan pwosesis rembousman an, tanpri kontakte nou. service@roymall.com oswa Whatsapp: +8619359849471
Features:
- Fixed turn lamp current is 0.1 times the current value ( Used to identify whether the battery is fully charged When charging).
- Made from a dedicated benchmark IC and high-precision current sensing resistor, proving a more stable constant current, (when 20°C to 100°C constant current 1A, temperature drift less than 1%). Particularly suitable for LED.
- High output current, the max output current can reach 8A.
- Four high frequency capacitance, can lower output ripple, enhance the work stabilization.
- Double heat sink design. MOS schottky diode independent heat sink,which heat dissipation is good,and wonu2019t affect each other.
- Using large size Sendust Core and double pure copper wiring, improve working efficiency, reduce fever.
- 3296 multiturn potentiometer,high accuracy voltage and current regulation, good stability.
- Double color lamp, working condition be clear at a glance
- Voltage and current are adjustable,wich effect is good.
Parameters:
- Module Properties: Non-isolated step-down constant current, constant voltage module (CC CV) charging module
- Input Voltage: DC 7-32V
- Output Voltage: (1) DC 1.2-28V continuously adjustable. (2) Fixed output:Choose between 0.8v-28v
- Output Current: 8A (when power tube"s temperature exceeds 65 degrees, please add cooling fan)
- Constant Current Range: 0.2-8A (Adjustable)
- Turn Lamp Current: Constant current value * (0.1), turn the lamp current and constant value linkage, such as constant current value is 3A, turn the lamp current is set to a constant current is 0.1 times (0.1 * 3A = 0.3A)
- Lowest Pressure: 1V
- Output Power: Maximum power is about 200W
- Conversion Efficiency: Up to about 95%
- Operating Frequency: 300KHz
- Output Ripple: 20M bandwidth
- Input 24V output 12V 5A ripple around 50mV (Excluding noise)
- Output Short Circuit Protection: Yes, constant current
- Input Reverse Polarity Protection: None
- Output Prevent Backflow: None
- Wiring: Terminal

- Voltage Regulation: ± 1%
- Dynamic ResponseSpeed: 5% 200uS
- Potentiometer Adjustment Direction: clockwise (increase) , counterclockwise (decrease), the potentiometer(CV) closed to the input voltage is used to regulate voltage, the potentiometer(CC) closed to output voltage is used to regulate current (CC)
- Operating Temperature: Industrial grade (-40 °C to +85 °C) (please note the actual use of the power tube temperature , high temperature heat strengthened)
- Indicator: dual color indicator, charging indicator light is red, the green light means fully charged (No load is green)
- Size: Approx. 65 x 47 x 23.5mm/2.56 x 1.85 x 0.93""
- Precision of Constant Current and Temperature: On the actual test, the module temperature from 25 degrees to 60 degrees, the constant current value change is less than 5% (5A constant current value)
- Output Short Circuit Protection: Yes,Constant current (the current setting constant current value)
- Input Reverse Connect Protection: NO
- Output Prevent Reverse Fow: NO
- Wiring Method: Amphenol connector
