Features Can be connected to the load within 2A, AC or DC input voltage, output voltage DC 1.25V-28V can be adjusted continuously. Stable performance: Adopt high frequency power supply special capacitor, more stable performance. Using the bidirectional adjustment potentiometer. Display features: Add digital tubes to display the output voltage, the output voltage is clear at a glance. Military grade double sided circuit board. Specification: Input voltage: DC 3-30V/AC 3-20V Output voltage: DC 1.25V-28V Output current: Max. 2 A Board size: 72*39*28mm/2.83*1.53*1.1in Mounting size: 65*32mm/2.56*1.26in Mounting hole: 3mm Approximate weight. 43g/1.5oz Packing list: 1 * Adjustable Voltage Regulator Note: 1. Since the working voltage of digital tubes is 4.5V, it is normally displayed only when the voltage is higher than 4.5V. 2. While inputting 5V, it can output 1.25-2V and does not output a higher voltage. Package List
