MEAN WELL OWA-200U-24 is a moistureproof AC/DC adapter with 24 VDC, 8.3 A and 199 W rated output. Match the connected equipment to its fixed output voltage and rated current. This U version uses a NEMA 1-15P AC plug and 100–264 VAC input. The IP67 rating is for the power body; connector protection must suit the installation.

Protection and operating conditions
Parameter
Specification
Overcurrent protection
105–150%; hiccup mode, automatically recovers after the fault is removed.
Short-circuit protection
Hiccup mode, automatically recovers after the fault is removed.
Overvoltage protection
27–34 V; output shuts down. Remove the fault and re-power to recover.
Overtemperature protection
Output shuts down. Remove the overtemperature condition and re-power to recover.
Ambient temperature
−40 to +70°C, subject to derating. Operation from −40 to −25°C is specified only at 230 VAC.
Cooling and load derating
Fanless free-air convection with the recommended horizontal mounting. At 110 VAC: 100% load through +40°C, decreasing to 40% at +70°C. At 230 VAC: 100% load through +45°C, decreasing to 50% at +70°C. Apply thermal and input/load limits together; the upper ambient limit is not a full-load rating.
Input/load curve
At 60 Hz: 80% load at 100 VAC, rising to 100% at 110 VAC and remaining at 100% through 264 VAC.
Humidity and storage
Working: 20–95% RH, non-condensing. Storage: −40 to +80°C, 10–95% RH.

Safety and compliance
Parameter
Specification
Catalog safety and construction
Class II power unit, no FG connection; fully silicone-potted plastic enclosure with 94V-0 flame-retardant housing. IP67 applies to the power body, not an unrestricted waterproof rating for plugs or the complete installation. UL62368-1; UL1012 is a design reference. Suitable for dry and damp locations as catalogued.
Energy-efficiency declarations
Energy efficiency Level VI; EU ErP requirements are stated in the catalog. CoC Version 5 is also stated for this model.

Disconnect AC power before connecting the DC plug, installing, cleaning or servicing, and prevent accidental reconnection. Check voltage, polarity, connector size and current rating before use; never force an incompatible plug. Keep connections secure and protect cables from damage. Provide ventilation and leave 10–15 cm clearance when an adjacent device is a heat source; do not stack objects on the unit. Follow the catalog’s horizontal mounting and load curves; nonstandard mounting or high ambient temperature may require additional derating. Keep plugs and connections appropriately protected; do not immerse the unit in water. Do not open the enclosure. Damaged external cables must be replaced by the manufacturer, a service agent or similarly qualified personnel. Verify insulation, interconnections and EMC in the final equipment.
For battery-charging applications, the catalog recommends operation with a BMS controller. Confirm the battery and charging-control requirements for the complete system before use.
Separate plug converters
The DC plug guide lists separately sold DC PLUG-R7BF-P1J (2.1 mm ID × 5.5 mm OD × 11 mm barrel) and DC PLUG-R7BF-P1M (2.5 mm ID × 5.5 mm OD × 11 mm barrel) for the standard OWA-90U–200U R7B interface. Verify mating, polarity and current compatibility for the actual output before use; a converter must not be assumed to carry the full rated current of every model.
Specification notes
Unless otherwise specified, catalog parameters are measured at 230 VAC input, rated load and 25°C ambient. Typical efficiency, power factor and time values depend on operating conditions; protection thresholds do not authorize continuous overload. The manufacturer catalog states a 5-year warranty; applicable manufacturer terms govern.
