Datasheet
**OWA - 90E series** 90W Single Output Waterproof Switching Adaptor ## **IP67** ## ■ **Features** - ‧Universal AC input / Full range (up to 264VAC) - ‧Built-in active PFC function - ‧High efficiency up to 91% - ‧Protections: Short circuit / Over current / - Over voltage / Over temperature ## ■ **Applications** - ‧Robotic lawn mower - ‧Household appliance - ‧Battery charging - ‧General electronic products in dusty or humid environment - ‧Class Ⅱ power unit, no FG - ‧Fanless design, cooling by free air convection - ‧No load power consumption <0.15W - ‧ErP step 2 - ‧5 years warranty ## ■ **Description** OWA-90E is a 90W AC/DC, class Ⅱ (without earth pin) external power supply series pinpointing the waterproof feature. The fully-potted silicone inside the plastic enclosure enhances the heat dissipation; it also benefits that the OWA-90E achieves **I** P67 level so that this series specializes the application in which the damp, humidity or dust resistance is needed for the external power supply. The no load power consumption is less than 0.15W, following the major demand for adaptors concerning the energy efficiency in Europe. Moreover, OWA-90E fits the applications requiring EN60335 such as household appliances, greatly simplifying the system design. OWA-90E adopts the universal input range from 90VAC to 264VAC and incorporates a built-in PFC function. With the working efficiency up to 91%, OWA-90E is cooled by free air convection; the working temperature ranges from -40℃ to +70℃. ## ■ **Model Encoding** **OWA - 90E -** [| **12** Output voltage Europe type of plug Output wattage Series name _File Name:OWA-90E-SPEC 2014-01-20_ **OWA - 90E series** 90W Single Output Waterproof Switching Adaptor ## **SPECIFICATION** ||**MODEL**<br>**DC VOLTAGE**<br>**RATED CURRENT**<br>**RATED POWER**<br>**OUTPUT**<br>**LINE REGULATION**<br>**LOAD REGULATION**<br>**SETUP, RISE TIMENote.4**<br>**HOLD UP TIME (Typ.)**<br>**VOLTAGE RANGE**<br>**FREQUENCY RANGE**<br>**POWER FACTOR (Typ.)**<br>**EFFICIENCY (Typ.)**<br>**AC CURRENT (Typ.)**<br>**INPUT**<br>**INRUSH CURRENT (**<br>**.)**<br>**Typ**<br>**LEAKAGE CURRENT**<br>**WORKING TEMP.**<br>**WORKING HUMIDITY**<br>**STORAGE TEMP., HUMIDITY**<br>**TEMP.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
