500mW LED Bulb Testing

Setup – We have provided 220 Volts AC Input to the SPEA-1 source and connects

the 0.5W led bulb at load. Micro SD Card is inserted in SPEA-1. For real time data

viewing we have connected SPEA-1 to the software through USB

In the above Image Vrms, Arms, W, VTHD, ATHD, and serial no is showing. SPEA-1 is in

production mode. As per image in display column 1 Vrms is 221.4Volts, Arms is

14.43mAand Watt is 0.332 watt. In Display column 2 VTHD% is 1.2 and AmpTHD% is

19.7.

In the lower display serial no of testing model shows which is 1124. THD TYPE LEDs

and PERCENT LEDs are OFF. This also shows that SPEA-1 is in production mode. (Mode

has been discussed on HOME page). You can also view more information on SPEA-1

Details .

In the above image SPEA-1 is in R&D mode.In display column 3, Left side shows

harmonics value/Percent and right side shows serial no or level of harmonics. Last

display so Harmonics is showing in place of Serial No. Harmonics type is Voltage and

image shows the value of 3rd harmonic.
