20W High performance AC/DC Converter - LH20-23BxxR2 Series

MORNSUN launched 20W AC/DC converters LH20-23BxxR2 series for Class I equipment (including PE systems), which are requiring high performance in power supply modules. The new series in 305RAC family have the same layout size as the LHE20-20B series, but with higher performance, higher efficiency, and greater environmental adaptability. 

 

They are the cost-effective solution with high EMC performance by adding a common-mode EMI filtering circuit and protecting earthing (grounding), which can be widely applied in the output-PE system or AC charging pile/box with the circuit of Y capacitor-PE system.

 

 

Advantages

1. Miniature size: 62.0 * 45.0 * 22.5mm (Compatible with LHE series)

 

2. Wide input voltage range: 85 - 305VAC/100- 430VDC

The products are in MORNSUN "305RAC" family, meeting a criterion of universal voltage requirement and various regions' electricity power voltage of 110VAC, 220VAC, 240VAC, and 277VAC. It can operate reliably for a long time even under the condition of power grid fluctuation.

 

3. Wide operating temperature: -40℃ to +85℃

The products can work without derating in the range of -25°C to +55°C and stably operate in extremely cold weather or poor ventilation environment.

 

4. High efficiency

Low standby power consumption as low as 0.3W, efficiency up to 86%, and low ripple & noise

 

5. High reliability

① High EMS performance: Lightning surge, EFT meets IEC/EN61000-4-4 ±4KV

② 4200VAC high isolation voltage, 5000m altitude application

③ Plastic case meets UL94V-0 flammability

④ Safety according to OVC Ⅲ (meet IEC62477-1, 2000m altitude) and IEC/EN/UL62368 standards

⑤ 3-year warranty

 

 

Applications

LH20-23BxxR2 can be widely used in industrial control system, smart home, smart building, intelligent agriculture, household appliance, etc.
