PW-250AS Series 250W Desktop Adapter Power Supplies with ON/OFF Switch

The 250W Desktop Adapter Power Supplies with ON/OFF Switch deliver high-capacity power conversion for general applications. They feature a universal AC input, high power factor, ultra-low no-load power consumption, and efficiency of over 89%. In addition, Conexa Tech builds these safety- and EMC-approved adapters into a durable black plastic case featuring an integrated physical switch and a “Power-ON” LED indicator, which ensures dependable performance for demanding electronics.

Key Features & Electrical Specifications

• Universal Inputs & Control: Specifically, these adapters accept a universal AC input range of 90 to 264VAC (47 to 63Hz) with a high power factor of >0.90 at 230VAC full load via an IEC320-C14 (Class I) connector. They also feature a convenient physical ON/OFF switch fitted directly on the case end adjacent to the input connector.

• Precision Outputs: Furthermore, this series features a single output ranging from 12 to 54VDC, offering output regulation of +5%/-5% alongside low ripple and noise (300mV p-p Max).

• Protection & Efficiency: As a result of an advanced internal design, built-in protection guards against over-current (OCP), over-voltage (OVP), and short-circuit (SCP) conditions. Meanwhile, units meet efficiency requirements with an average efficiency of over 89% and a no-load power consumption of under 150mW.

• Customization: Moreover, engineers can customize output voltages, casing colors (subject to minimum order quantities), and cable connectors for high-volume project requirements.

Mechanical & Environmental Characteristics

• Enclosure & Cabling: In particular, manufacturers house these units in a robust black plastic case measuring 200 x 90 x 45mm, equipped with a 0.8M output cable that can be fitted with standard plugs or supplied bare-ended.

• Thermal & Operational Standards: Overall, they operate reliably across a wide temperature range of -20 to +60°C (derating below zero and above 40 degrees), making them ideal for protected indoor environments.

• Compliance: Consequently, they meet rigorous global safety standards including IEC/EN/ETL62368-1 (with UL, TUV, and CB approvals) and comply with EMC standards including EN55024 Class B, EN55032 Class B, and FCC Part 15 Class B.
