6AG1307-1KA02-7AA0 SIPLUS PS 307 10 A Power Supply

6AG1307-1KA02-7AA0 SIPLUS S7-300 PS 307 10 A Power Supply

The 6AG1307-1KA02-7AA0 is a SIPLUS variant of the S7-300 PS 307 supply. It is based on 6ES7307-1KA02-0AA0 and adds conformal coating. Input takes 120 or 230 V AC and output holds a stable 24 V DC at 10 A. The coated board runs from -25 to +70 °C. SELV output meets EN 60950-1 and EN 50178. Efficiency sits near 90% at rated load. This unit suits plants with humidity, dust, and chemical exposure.

FAQ

Q: Can I drop this unit into a rack wired for 6ES7307-1KA02-0AA0?

A: Yes. The SIPLUS version shares the base design. Check the 24 V rail load and wiring before swap.

Q: How much current can I pull at 65 °C cabinet temperature?

A: Plan for 7 A, not 10 A. Derating starts above 60 °C.

Q: What does conformal coating change in practice?

A: It resists humidity, dust, and chemical gas. It does not add waterproofing to connector pins.

Q: Is 100% humidity with condensation really allowed?

A: The unit is tested for it. However, do not commission under condensation. Dry the panel first.

Q: What should I check on a used SIPLUS PS 307?

A: Ask for 24 V output readings under load, coating photos, and fan-free heatsink checks. Confirm the 12-month warranty.
