Product questions
What input voltages does the 2866792 power supply accept?
The specified ranges are 320–575 V AC three-phase, 360–575 V AC two-phase, or 450–800 V DC. The nominal three-phase AC input is 400–500 V and the AC frequency range is 45–65 Hz. Verify the supply and installation requirements before selection.
Is the output voltage adjustable on the 2866792?
Yes. Its nominal output is 24 V DC at 20 A, and the output can be adjusted from 18 to 29.5 V DC. The wider 5–56 V range sometimes associated with QUINT POWER refers to the product range, not this specific unit.
What do POWER BOOST and SFB provide on this power supply?
At 24 V DC, POWER BOOST provides 26 A continuously from -25 to +40 °C. SFB provides 120 A for 12 ms to help trip suitable downstream circuit breakers. Breaker selection and circuit conditions still matter.
Can the 2866792 operate at 70 °C?
The specified operating range extends from -25 to +70 °C, but output must be derated above +60 °C by 2.5% per kelvin. The 20 A nominal output at 24 V applies up to +60 °C; check the installation conditions and load.
Can 2866792 power supplies be connected in parallel or series?
The exact-part datasheet lists parallel operation for redundancy or increased capacity and also permits series connection. The overall circuit design and the manufacturer’s instructions must be checked before installation.
