Specifications

• Output Current: Max 20A, Suggested 15A
• Output Voltage: 1.2V – 36V DC
• Efficiency: 95% (24V to 12V, 20A)
• Output Ripple: ≤50mV
• Wiring Method: Terminal
• Short Circuit Protection: Self-recovery (avoid prolonged short circuit)

Pinouts

• VO+ : Output Positive
• VO- : Output Negative
• +IN : Input Positive
• -IN : Input Negative
• CV : Voltage Adjustment
• CC : Current Adjustment
• EN : Enable (Low voltage shuts off output; high voltage enables)

Precautions

• When input and output share a common ground: no-load CV outputs constant voltage; CC outputs constant current
• Operating Temperature: -10°C to 75°C
• Dual MOS tube design: 75V / 80A for high current applications
• Two heat sinks for efficient heat dissipation

Applications / Uses

• Industrial automation and scientific research equipment
• LED lighting and air purification systems
• Civil equipment and solar panel voltage regulation
• Battery charging for wind turbines and other high-power devices

Note

Colors may slightly vary due to lighting and display differences. Measurement tolerance: ±1-3 cm.
