Features: _x000D_ Can be connected to the load within 2A, AC or DC input voltage, the output voltage is DC 1.25V-28V continuously adjustable. _x000D_ Adopt high-frequency power supply dedicated capacitor, more stable performance. _x000D_ Using duplex adjustment potentiometer. _x000D_ Add digital tubes to display output voltage, the output voltage is clear at a glance. _x000D_ Military grade double-sided circuit board. _x000D_ With a heat sink for better heat dissipation. _x000D_ _x000D_ Specification: _x000D_ Input voltage: DC 3-30V / AC 3-20V _x000D_ Output voltage: DC 1.25V-28V _x000D_ Output current: Max. 2A _x000D_ Board size: 72*39*28mm / 2.83*1.53*1.1in _x000D_ Mounting size: 65*32mm / 2.56*1.26in _x000D_ Mounting hole: 3mm _x000D_ Weight: Approx. 43g / 1.5oz _x000D_ _x000D_ Package list: _x000D_ 1 * Adjustable Voltage Regulator _x000D_ _x000D_ Note: _x000D_ 1. Because the working voltage of digital tubes is 4.5V, it displays normally only when the voltage is higher than 4.5V. _x000D_ 2. When inputting 5V, it can output 1.25-2V and won't output a higher voltage.
