Product details

Sourcing at a glance

The 6AG1334-2BA20-4AA0: Active current production — no last-time-buy or phase-out to watch. This is a standard SITOP catalog item: 24 V DC output, adjustable 22.8–28 V to compensate for voltage drop on long cabling. Rated 10 A continuous, with headroom to 12 A up to 45 °C; above that, derate 3 %/K to 70 °C. Efficiency hits 90 % at rated load, so panel heat dissipation stays low.

Screw terminals: one each for L, N, PE at line side (0.5–2.5 mm²), two each for + and – at load side (same wire range). Keep 50 mm clearance above and below the enclosure for convective cooling — zero clearance left/right so you can gang units. IP20, so fit in a clean, dry cabinet.

Control and signalling

Automatic range selection — feed it 85–132 V or 170–264 V AC, 47–63 Hz, and it picks the tap. A relay output (NO contact, 60 V DC / 0.3 A) asserts when the 24 V rail is healthy; two alarm signal terminals (screw, 0.5–2.5 mm²) carry that. Response delay on power-up under 0.3 s.

Frequently asked questions

What compliance documentation does this power supply carry?

CE marked, safety extra-low voltage per EN 60950-1 and EN 50178. No UL or other agency marks listed in the spec sheet.

What are the mounting clearances?

Must maintain 50 mm clearance above and below for airflow. Zero clearance left and right — units can be mounted side-by-side. DIN rail mounting per EN 60715.
