FAQ |
|---|
| Q1: What does "GPU" stand for in this context? |
| A1: GPU stands for Ground Power Unit. It is a mobile or stationary unit that supplies electrical power to an aircraft on the ground. |
| Q2: Why is 400Hz power required for aircraft? |
| A2: 400Hz AC power is the international standard for most commercial and military aircraft because it allows for lighter and more efficient electrical components in the aircraft's systems. |
| Q3: Can this GPU be used for both commercial and military aircraft? |
| A3: Yes. The ACSOON GPU is designed to meet the power quality specifications (like MIL-STD-704F) common to both sectors, making it versatile for various aircraft types. |
| Q4: What is the purpose of the auto voltage compensation feature? |
| A4: It automatically adjusts the output voltage to account for voltage drop in the output cable, ensuring the aircraft receives the correct voltage (115V) at its connector regardless of cable length. |
| Q5: Is remote monitoring possible? |
| A5: Yes, models are typically equipped with RS232/RS485 communication ports for integration into airport ground power monitoring systems. |
