MEAN WELL OWA-120E series: Moistureproof AC/DC Adapter - OWA-120E-54

Description

MEAN WELL OWA-120E-54 supplies 54 V DC at 2.3 A, with a rated output of 124.2 W. This Class II, fanless adapter uses a European AC plug and a standard XLR four-pin DC connector. Its fully potted power body is rated IP67; the DC connector is outside that rating. Observe the input and temperature derating limits.

Catalogue packing reference per unit 1.15 kg (1150 g), as the per-unit PACKING reference; not a measured net weight or shipment weight.

Check the connector view and pin numbering in the mechanical drawing before wiring. The marked Tcase point identifies the case-temperature measurement location. Keep the connection and installation conditions within the complete system's requirements.

Optional factory DC connectors

Lumberg 3611 03 or equivalent Pin 1: +V; pin 2: floating; pin 3: −V.
XLR 3-pin NEUTRIK NC3MX or equivalent Pin 1: +V; pins 2 and 3: −V.
CHOGORI 22002411-01 or equivalent Pin 1: +V; pin 2: −V.
CHOGORI 23002411-01 or equivalent Pin 1: +V; pin 2: −V.
Unicable UT-D170F4-2P or equivalent Pin 1: +V; pin 2: −V.
Unicable UT-D224-2P or equivalent Pin 1: +V; pin 2: −V.
Tuning-fork barrel connector 2.1 mm inside diameter × 5.5 mm outside diameter × 11 mm length; centre positive, outer sleeve negative.

These are alternative factory output configurations, not additional connectors supplied with the standard model. For this 54 V, 2.3 A supply, confirm that the selected complete connector and cable assembly supports the intended load voltage and current; connector shape or matching polarity alone does not establish full-load compatibility.

Specify the connector, pin numbering and cable requirements when ordering. The optional barrel connector dimensions do not by themselves establish its current rating. The IP67 power-body rating does not extend to the DC connector.

Reliability and measurement notes

MTBF reference 2902.2 thousand hours minimum, Telcordia SR-332 (Bellcore); 294.4 thousand hours minimum, MIL-HDBK-217F at 25°C.
Catalogue warranty The manufacturer's series datasheet lists a 5-year warranty; its terms and applicability govern.
Catalogue version 2024-10-16

Unless otherwise specified, parameters are measured at 230 VAC input, rated load and 25°C ambient.

Ripple and noise are measured at 20 MHz bandwidth using a 12-inch twisted-pair wire terminated with 0.1 µF and 47 µF capacitors in parallel.

Voltage tolerance includes set-up tolerance, line regulation and load regulation. Set-up time is measured at a cold first start; repeated ON/OFF operation may increase set-up time.

Apply all temperature, input-voltage, output and connector limits together. Integration, wiring and the final equipment's compliance must be checked for the intended installation.
