Product questions
What input and output ratings does Phoenix Contact 2866776 have?
It accepts a nominal single-phase 100–240 V AC input, with an 85–264 V AC operating range. Its nominal output is 24 V DC at 20 A, or 480 W. The documented DC input range is 90–350 V DC.
Can the output of 2866776 be adjusted to 28 V DC?
Yes. The specified adjustment range is 18–29.5 V DC, so 28 V is within range. Above 24 V, output capacity is restricted; check the load requirements and the current manufacturer documentation before selection.
What are POWER BOOST and SFB on the 2866776?
POWER BOOST provides 26 A continuously at 24 V DC from −25 to +40 °C. SFB provides 120 A for 12 ms to help trip suitable circuit breakers. These are different from the nominal 20 A output rating.
Can two 2866776 power supplies be used for redundancy?
The manufacturer datasheet describes parallel operation for redundancy or increased capacity. For full redundancy it specifies external decoupling diodes and sizing each supply to carry the complete load. Check the system design and current documentation before installation.
How does temperature affect the 2866776 output?
The datasheet states that nominal current is available up to 60 °C; above 60 °C, output current must be reduced by 2.5% per kelvin. The specified operating range is −25 to +70 °C.
