SITOP 6AG1436-2BA10-7AA0 at a glance
This Siemens SITOP power supply delivers a controlled, isolated 24–28 VDC adjustable output at a full-scale 20 A, with a rated range of 0–20 A and 91% efficiency at 400–500 VAC input (47–63 Hz). Galvanic isolation to EN 60950-1 and EN 50178 ensures safe low-voltage outputs; the unit carries CE marking and meets EN 55022 Class B for emissions and EN 61000-6-2 for immunity. MTBF is rated 500 000 h at 40 °C, with a typical current draw of 1 mA (max 3.5 mA).
Panel mounting and clearances
Snaps onto DIN-rail EN 60715 (35×7.5/15). Enclosure dimensions: width 90 mm, height 145 mm, depth 150 mm. Adequate airflow requires 40 mm clearance above and below the unit; side clearance is 0 mm — modules can be abutted in a row without spacing. Protection class IP20 — suitable for clean, dry control cabinets only.
Connections and accessories
Input (, L2, L3, PE) accepts 0.5–4 mm² single-core or finely stranded wire per screw terminal. Output (+/−) accepts 0.2–4 mm². A separate alarm relay (NO contact) is on terminals 13–14. Electrical accessories listed by the manufacturer include a redundancy module, buffer module, selectivity module, and DC UPS for extended hold-up or dual-feed configurations. The feeder circuit must be protected by a 3-pole miniature circuit breaker (6–16 A, characteristic C) or a Siemens 3RV circuit breaker (setting 3 A) per the spec.
