CONT. EQ. 18 WM, 60°C CB scheme IEC60950 Input Output Input voltage 3 AC 400–500 V, ± 15 % 47-63 Hz, suitable for IT power systems Rated tolerances • Continuous operat. • Short term (1 min.) (at 24V/5A) 340...576 V AC resp. 450...820 V DC 300...620 V AC resp. 420...890 V DC Even if one phase fails, the unit’s operation with nominal current can be continued (limitations: EN 61000-3-2 (harmonic current emissions) is then not fulfilled, the unit has noise suppression level A instead of level B and the hold-up time is shorter). Continued operat. with two phases is also permissible; however, it reduces the unit’s reliability and lifetime.
