Power Supply for DC-Bus Applications
The 4 A rating holds up to +55 °C ambient; above that, derate 3% per K, reaching 2.2 A at +70 °C — so if your enclosure runs hot, size for the derated figure, not the headline 4 A.
Clearance and Mounting
Requires 50 mm clearance above and below the unit for natural convection cooling — no forced air needed, but don't box it in. Left and right clearance is 0 mm, so units can be ganged side-by-side without spacing. IP20 rated, so it's for clean, dry enclosures only; not for washdown or outdoor locations.
Input and Protection
AC input range 100-230 V, 47-63 Hz; DC input range 85-264 V (110-300 V rated). Internal fuse protection; the feeder should use a 16 A characteristic B or 10 A characteristic C MCB. Maximum I²t is 3 A²·s. MTBF at 40 °C is 2,726,727 hours.
