Electrical parameter measuring work bench

By Amrit Jain

Dear all.
I have an SMPS with me with a connected load(LED light)
I have only two terminals of input AC supply,which are open. I need to design a workbench which can check I/P voltage, Current, PF, THD, Wattage all in one. there will be 5 separate meters to measure each individuals. I just need to know how these meters will be connected in series or parallel.
What are the precautions which need to be taken while making this test bench.

i have a auto transformer with me, so i also want to have a voltage range feature in this.
like at 85V, what is the all other parameters, at 150V, what are all other parameters etc.

Please suggest some good electrical connection diagram with all necessary precautions mentioning each.

Fairchild Semiconductor’s Power Supply WebDesigner Now Provides CCM, Non-Isolated PFC Buck and Buck LED Driver Designs in Under a Minute

New Modules Provide Optimal Design with Complete Schematics, Inductor Design and Bill of Materials

SAN JOSE, Calif.–(BUSINESS WIRE)– Fairchild Semiconductor (NYS: FCS) , a leading global supplier of high performance power and mobile semiconductor solutions, has enhanced Power Supply WebDesigner – an online design and simulation tool that provides complete designs in under a minute – to include complete continuous conduction mode (CCM), non-isolated active PFC buck and buck LED driver designs.

From user-specified design inputs, the Power Supply WebDesigner (PSW) tool allows designers to choose all the components used in a design or have the tool automatically recommend the design values – providing Fairchild part numbers where applicable. PSW can automatically recommend design values, or allows the user to evaluate their own component choices.

While using the tool, designers can accept default recommended values, or spend time optimizing the important details to their unique design needs. Designers can get quick, accurate estimates on design performance, and refine design choices as they go. The tool also allows them to spend the time to perform detailed simulation analysis and learn the insights of how their design and its hardware prototype will work with higher degree of confidence.

When a design is complete, PSW creates a BOM which can be sent to their procurement department or instantly procure the components online, saving time on documentation or sourcing parts elsewhere. Additionally, they can save their design for future reference or pass the design on to other engineers.

Using the Power Supply WebDesigner tool provides the inexperienced designer a quick guided design, while the experienced designer can take their requirements and further customize critical design factors.

Updates:

  • Fairchild’s latest CCM buck and non-isolated PFC buck LED drivers are added options for PSW users, supporting Fairchild’s family of LED drivers.
  • First-available LED online tool designed to help design EMI filters, predict power factor (PF) and total harmonic distortion (THD).
  • PSW features have been extended to include the special driver requirements of low power (≤ 20W) …read more
