["This PoE voltage amplifier is a robust and versatile solution for demanding environments. It increases the low input voltage to deliver PoE to end devices and ensure stable voltage output to your PD in harsh environments. With an input voltage range of 12VDC, it efficiently boosts the voltage to 54VDC while delivering 100W of power. Alternatively, with an input voltage range of 24VDC, it boosts the voltage to 54VDC and delivers robust power of 200W. An adjustable voltage regulator allows you to fine-tune the output voltage between 52VDC and 54VDC to meet the needs of your devices. This voltage amplifier has been rigorously tested for safety, transportation and telecommunications applications to ensure reliable performance in extreme conditions.
