Testing Setup

To start testing of LED Driver We need to have below setup-

  1.  Test and Measurement Instrument with Harmonics Measurement
  2.  Testing LED Device with Specifications
  3. Micro SD Card or Computer
  4. Wires or Connecting Probe
  5. AC Power Supply

Our setup-

  1. We are using SPEA-1 which is developed and manufactured by Embuilt Technologies. You can also use other single Phase Power Analyzers from Fluke or Yokogawa. We have taken SPEA-1 beacuase it has some advanced features which makes testing easier.
  2. We have taken 0.5Watt LED bulb for testing. Generally low watt devices are not tested by some instruments and 0.5 Watt led bulbs are used widely as night lamp.
  3. Both SD Card and Computer (You can use one of them or both).
  4. Connecting Probe are used
  5. Single Phase Variac for variable power supply.

We have taken SPEA-1 which is manufactured by Embuilt Technolgies for testing of LED Drivers/SMPS/Single Phase AC devices with harmonics.

It has various parameters –

AC Volt, AC- Amps, AC Watt,  PF, Frequnecy, Voltage THD, Amps THD.

Voltage and Current Harmonics upto 55th Level.

Advanced parameter such as Crest Factor, Form Factor, Peak , Average and RMS of Voltage and Current.

SD Card Support for Reporting and Data Logging. For more details visit www.embuilt.com.

 

You can also use others power analyzer such as YokogawaWT310 .

Alarm Limit Specifications

 

To start testing first we specify the testing parameters Limits and enter in the software provided with SPEA-1.

(Optional) Connect Software with SPEA-1 to insert the testing model limits. This is one time requirement. Once the model limits are saved in SPEA-1, it will not remove on system off. It will store in SPEA-1 permanent memory. It can be replaced by another using software.

 

Insert Micro SD Card in its slot. All production reports on write button click will save here.
