Model and Configuration
| Complete order model |
OWA-200U-24. |
| Model code |
OWA-200U identifies the North American AC-plug version; the final 24 code identifies 24 VDC. |
| Power-supply construction |

| Input-voltage curve |
At 60 Hz, 80% load at 100 VAC, rising to 100% at 110 VAC; 100% across 110–264 VAC. |
| Working humidity |
20–95% RH, non-condensing. |
| Storage conditions |
−40 to +80°C; 10–95% RH. |
| Temperature coefficient |

| Vibration |
10–500 Hz, 5 G; 12 minutes per cycle and 72 minutes each along the X, Y and Z axes. |
Apply the most restrictive current, power, temperature and input-voltage limits together. The maximum ambient temperature is not a full-power operating point.
The power-factor plot is a typical 200 W load characteristic. The efficiency-versus-load plot is specifically for the 48 V model at 115 VAC and 230 VAC. It is not a guaranteed efficiency curve for every output-voltage version.
Mechanical Details and Installation
| Body size |

The standard connector for this model is R7B. The options above are the connector forms listed for this output-voltage version. Specify the required assembly before ordering; do not append unlisted connector suffixes to the model number.
Optional DC plug kits are sold separately. A connector rating does not increase the power-supply rating. Use the lower permitted current of the supply, connector and cable, and verify the mating contact numbers before connection.

Applications and Selection
Application examples include industrial PCs, POS and kiosk systems, portable battery or electric-lawn-mower charging equipment, household devices, and electronic products used in dusty or humid environments.
For battery-charging applications, the manufacturer recommends a BMS controller. Confirm compatibility with the battery and charging system; the power adapter alone is not specified here as an autonomous battery-charge controller.
Select the exact North American input version, output voltage, load rating and connector required by the equipment.
