FAQ |
|---|
| Q1: What is the primary use of a 28VDC 1000A rectifier in aviation? |
| A: It serves as a Ground Power Unit (GPU) to supply 28-volt DC power to an aircraft's electrical system while on the ground, allowing for engine starts, systems testing, and maintenance without draining the aircraft's batteries or running its APU. |
| Q2: How does this rectifier ensure safety for the connected aircraft? |
| A: It incorporates multiple layers of protection (over-voltage, over-current, reverse polarity protection via external contactor) and is built to military standards that define safe voltage and ripple limits for aircraft equipment. |
| Q3: Can the output voltage be adjusted for different applications, like battery charging? |
| A: Yes. The output is fully adjustable from 20V to 32VDC, making it suitable for charging 24V battery banks (requiring ~28V) or for other industrial DC applications. |
| Q4: Is this a standalone unit or can it be integrated into a larger system? |
| A: It can be used as a standalone cabinet, integrated into a custom GPU cart or trailer, or even paralleled with other units for higher current requirements. Communication ports allow for remote control and monitoring. |
| Q5: What are the installation requirements? |
| A: It requires a stable 3-phase AC power source matching its input voltage range, proper grounding, adequate space for ventilation, and connection by a qualified electrician following the provided manual and local codes. |
