7A DC 60V Adjustable Step Down Regulator NC Power Supply Current Voltage Meter Buck ModuleThis step down power supply module digitally displays output voltage and current draw. This enables you to monitor how much current your device is drawing while it's working with the correct voltage. This helps you determine what AC adapter will work with your project without overheating it. The down converter accepts a 60V AC/DC adapter, but we recommend 36 VDC 5A 120-063 adapter since the output is up to 32 VDC. Built-in short circuit protection for safe voltage down conversion.
Add this DC to DC buck converter to your next audio project that requires two different voltages with high current needs. Active speakers often use multiple amps to drive each individual speaker. A high wattage amp board for woofer may require up to 48 VDC. The Midrange and tweeter requires less wattage reducing the need for a high voltage, high cost amp boards. Smaller wattage amp boards also reduce the chance blowing small drivers. Now you need multiple power supplies for each board unless you use this voltage step down converter. In addition to the DC to DC buck converter it's recommended that you use power breakout board 320-3175 to distribute the power to each amp board preventing power feedback and unwanted noise that may occur.
Caution: If used for charging, when charging is completed, please disconnect the battery terminal first, and then disconnect the input to prevent battery backflow damage to the module! Or add an anti-reflux diode to the output.
Specifications: • Input voltage: DC 8 to 60V • Output voltage: 3 to 32 VDC continuously adjustable • Output current: 5A • Maximum output current: 7A short term • Input anti-reverse: Yes • Accuracy: 1%, voltage three-digit display, current two-digit display, unit is A • Load regulation: S (I) ? 0.8% • Voltage regulation: S (u) ? 0.8% • Dimensions: 2.44" W x 1.73" L x 0.71" H (62 x 44 x 18 mm).
Note:If voltage calibration is needed, remove input and output sources. Then hold the left button down (voltage decrease button) while reconnecting input power supply and release the button. The display will flash the output voltage. Use a multimeter to read the output voltage and if it doesn't match the flashing voltage press the left and right button until it matches the multimeter's voltage. After three seconds without pressing any buttons the calibration is saved. Repeat the process to calibrate the current reading except press and hold the right button (voltage increase button) while reconnecting power supply. Make sure you take a current reading with a multimeter to get the actual load measurement of the device hooked up to the board before you start the process.
