Key specs and what they mean for your panel
The 6AG1434-2BA20-7AA0: Load transient response is tight: 4 ms typical for a 10-to-90% step and 3 ms for a 100-to-50% step, so the supply handles sudden motor or solenoid pulls without dropping out. Galvanic isolation meets SELV per EN 60950-1 and EN 50178, with a safety extra-low voltage output. That means the 24 V bus is isolated from the mains — useful for protecting downstream controls from line transients.
Mounting, wiring, and feeder protection
Snaps onto DIN rail EN 60715 35×7.5/15. Enclosure is 70 mm wide × 125 mm high × 120 mm deep — fits a standard 4-module slot. Input terminals: one screw clamp per phase (, L2, L3) and PE, accepting 0.05–2.5 mm². Output: two screw terminals each for + and -, 0.2–2.5 mm². Auxiliary alarm relay terminals also provided (13, 14, 0.2–2.5 mm²).
Compliance and lifecycle
Listed as current-production (active); no end-of-life notice. The PSU carries CE marking and meets EN 55022 Class B for conducted and radiated emissions — low enough for residential limits, so it won't hash up nearby sensors or comms lines in an industrial cabinet. Compatible with SITOP add-on modules: redundancy, buffer, selectivity module, and DC UPS. If your BOM calls for a single-source power rail, this PSU slots into that ecosystem.
