Features Adopt dedicated capacitor for high frequency power supply, more stable performance. Military grade double sided PCB With heat sink for better heat dissipation. Can be connected to the load in 2A, AC or DC input voltage, the output voltage is continuously adjustable from 1.25V to 28V DC. Add digital tubes to display the output voltage, the output voltage is clear at a glance. Using duplex adjustment potentiometer. Specification: Input voltage: DC 3-30 V/AC 3-20 V Output Voltage: DC 1.25V-28V Output current: 2A maximum Card size: 72*39*28mm/2.83*1.53*1.1in Mounting size: 65*32mm/2.56*1.26in Mounting hole: 3mm Weight: approx. 43 g/1.5 oz. Features: Can be connected to the load in 2A, AC or DC input voltage, the output voltage is DC 1.25V-28V continuously adjustable. Adopt dedicated capacitor for high frequency power supply, more stable performance. Using duplex adjustment potentiometer. Add digital tubes to display the output voltage, the output voltage is clear at a glance. Military grade double sided PCB With heat sink for better heat dissipation. Package list: 1 x adjustable voltage regulator. Note: 1. Since the working voltage of digital tubes is 4.5V, it is normally only displayed when the voltage is higher than 4.5V. 2. When entering 5V, it can produce 1.25-2V and will not produce higher voltage. Package List
