20W Lift-Off Positive and Negative Voltage Module DC3.6-30V Multi-Function Car Audio ADC/DAC/Amplifier Power Module

20W Lift-Off Positive and Negative Voltage Module DC3.6-30V Multi-Function Car Audio ADC/DAC/Amplifier Power Module Features: 1. Why Is The Output Voltage Less Than The Nominal Voltage? This May Be Because The Load Is Too Large Or The Power Supply Is Too Small. 2. Why Is There No Negative Voltage Output Or The Output Is Too Low? Negative Voltage Cannot Be Used Alone. When Using Negative Voltage, The Same Load Must Be Added To The Positive Voltage End. 3. Positive And Negative Pressure Must Be Used At The Same Time, Otherwise There Will Be No Output Of Negative Pressure. 4. Input Positive Voltage, Output Positive Voltage 5.20W Buck-Boost Positive And Negative Voltage Module Description: 1. Input DC3.6-30V, Output DC±3-30V Adjustable 2. Maximum Output Power: 20w Maximum Conversion Efficiency: 68-89% 3. Quiescent Operating Current: 2.5mA 4. Size: About 60 x 34 x 15mm 5. Typical Applications: ADC/DAC/Transport Amplifier Power Supply; RS232 RS485 RS422 Bus Power Supply; Low-Power Audio Power Supply; Car Audio Power Supply; Instrument Power Supply; Lcd Backlight Power Supply Color: green Material: PCB Package Contents: 1 x Buck Module With Terminals Note: Different Batches May Have Differences In Product Appearance, Color, And Printed Characters, Which Will Not Affect The Use
