20A 300W DC to DC Step-Down Buck Adjustable Constant Voltage Constant Current Power Supply Module
Price in Sri Lanka

Features:

• Wide input voltage range from 6V to 40V
• Can accurately adjust output voltage and current
• The efficiency can be up to 96%, measured at 20A, converting 24V to 12V
• It is designed with 75V/80A large current dual MOS tube
• Input and output use high frequency low resistance electrolytic capacitor, low ripple, stable output
• Wiring is convenient with these large current 30A screw terminals
• The buck module has 2 heat sink that could enhance heat dissipation
• When there is a big difference between input and output voltage, please decrease power and current

Specifications:

• Input Voltage: 6 to 40VDC (10V to 40V is suggested)
• Output Voltage: 1.2 to 36VDC
• Output Current: 20A (max.), 15A (suggested)
• Efficiency: 95% (24V to 12V 20A)
• Output Ripple: ≤50mV
• Wiring Method: Terminal
• Short Circuit Protection: Self-recovery (cannot short circuit for long time)

Wiring Diagram:

• VO+: Output positive
• VO-: Output negative
• +IN: Input positive
• -IN: Input negative
• CV: Output voltage adjustment
• CC: Output current adjustment
• EN: Enable, low voltage level shut off output; suspension, high voltage level is effective
• When input and output is common grounded, no-load CV output constant voltage, CC output constant current
