Ventilation Control – LD10-20B12

CASE STUDY
"We need a reliable AC DC converter to power our ventilation controllers"

Request

The customer wanted a low profile, low cost PCB mount ac dc power supply to power monitoring and control electronics in a kitchen ventilation management system. The control box manages air conditioning and fan control whilst also providing gas detection.

  • LD10 Series

    Input: 85-264Vac
    Outputs: 3V3 to 24V
    Power: 10 Watt
    Tamb: -25 to +70°C
    Dims: 53.8 x 28.8 x 19mm
    UL / CE EN60950 Approved

Refine

We had to find a module that fitted with a 20mm height profile, but we also took them through their EMC requirements (needed EN55022 class B), thermal considerations (kitchens get warm) and long term reliability of the product.

  • LD05 Series

    Input: 85-265Vac
    Outputs: 3V3 to 24V
    Power: 5 Watt
    Tamb: -25 to +70°C
    Dims: 50.8 x 25.4 x 15.16mm
    UL / CE EN60950 Approved

Result

The LD10 has a wide 85 to 264Vac input with a single fixed dc output in a compact PCB mount package just 19mm high, which provided a good physical fit for this project. The kitchen environment also dictated extended operation at elevated temperatures; again the LD10 fulfils this with an operating temperature range of -20 to +70°C. A 300,000 hour MTBF backed with a 3 year warranty confirm that the LD10 will offer the required long term reliability, along with short lead times and a sensible price enable it to fit all of the requirements.

  • LD01 Series

    Input: 85-305Vac
    Outputs: 3V3 to 24V
    Power: 1 Watt
    Tamb: -25 to +70°C
    Dims: 33.7 x 22 x 18mm
    UL / CE EN60950 Approved
    3 Years Warranty
