Derating applies above 60 °C: 4%/K up to 70 °C. The output is adjustable, so you can trim it to 24 V or bump it to 28 V for longer cable runs. ## Not a Drop-In for Older SITOP Generations The PSU8200 has a 150 mm depth and requires 40 mm top clearance. Input uses single screw terminals per phase. ## Compliance and Cabinet Fit CE marked, EN 55022 Class B emissions (suitable for residential/commercial environments), EN 61000-6-2 immunity, and safety extra-low voltage per EN 60950-1 and EN 50178. Protection class IP20 – so mount inside a cabinet. Fastens onto standard DIN rail EN 60715 35x15. Physical dimensions: 135 mm wide, 145 mm high, 150 mm deep. The spec calls for 40 mm free space above the unit for proper ventilation – factor that into your enclosure layout.","metaTitle":"Siemens 6AG1437-8SB00-7AY0 SITOP PSU8200 24V 40A","metaDescription":"SITOP PSU8200 40 A power supply, input 400-500 V AC 3-phase, adjustable 24-28 V DC output, 94% efficiency, IP20, DIN rail.
