The new PAC 3A power supply units are designed to be eco-friendly but offer high performance levels. The PAC 3A PSU power supply unit is designed and tested to satisfy the most stringent standards of the California Energy Commission (CEC) Level 6. Their consumption is limited, thanks to their high efficiency (80% efficiency in most load scenarios), to provide a stable output at 24 VDC. They come with pre-wired cables as standard, for easy connection of backup batteries.
