Burn In Tester or Load Monitor for LED Drivers and Single Phase Devices
0 likes339 views
The document outlines the specifications and functionalities of a programmable range power tester (prpt-16) designed for testing LED drivers across a voltage range of 170-270V. It features 16 channels for measurement, software integration for limit setting, and visual indicators for load status. The tester can perform various tests, such as range testing and voltage fluctuation, without needing a computer in production environments.

- 1. —--- Programmable Range Power Tester Example LED Driver’s Specification - INPUT : 170-270 V~0.2 A, 50-60 Hz OUTPUT : 5 V 1 A EFFICIENCY - 80% output wattage ~ 4 Watt 170 V 270 V N We can Test Led Drivers on 16 Channel over its range and also program their Cycle of switching You can also give relay timing for switching between two voltages Channel 1 Channel 2 Channel 3 Channel 16 Connection Diagram Limit Set Software SnapShot prpt-16 Cyclic Switching Between Ranges User programmable Switching Time Limit Set Software Interface 16 Channel output/Measurement Here you can give timing for switching of relays. This will be transferred to PRPT-16 meter. So No need of computer in Production Testing. By this you can do range testing, Testing on Voltage fluctuation, On-Off Testing etc (Burn-in Tester)

- 3. Testing of multiple Drivers in single Channel You can also test more than 16 no. of LED Drivers using Cyclic Load Tester D1D2D3D4D13D14D15D16D11D8D9D5D10D7D6D12 16CHANNELPOWER MEASUREMENT CTs You can connect multiple Drivers in parallel. Load No Wattage D16 8.1 D15 8.2 D14 5.1 D13 8.5 D12 4.9 ------ —--- —--- ------ D1 8.3 In above D14 has two Drivers of 4.1 W So Total W = 4.1*2 = 8.2 So we set here the watt limit to 8. If any driver is fail then Related Load RED LED will show. But using multiple driver in one channel may produce fault result. If you are using Two Drivers and both are fail, then one driver can Produce more voltage or increase the wattage and other can be produce low wattage then total affect will be under the set wattage Limit . For above Example if at D14 Driver 1 produces 4.9 W and Driver 2 produces 3.2w Then Total Wattage = 4.9+3.2 =8.1 W So the total effect is above 8W and This will not detected. Here every Channel has two drivers of 4.1 Watt each. So we set the limit to 8 watt. In below table One Driver in Channel 14 and 12 are fail which is showing in red row

This will save in meter Enter the Voltage connected to relay This is only for graphing on switching Cycle Page Click here to add more Timeset for relay Switching Select the Relay and enter the time for switching Shows the Switching Cycle based on the voltage given and time set This information will transfer to the PRPT-16 Meter by USB Enter the Voltage limit for testing. It will off the relays beyond the set limit so Load will work on the safe voltage region Enter the Watt Limits for testing so if any driver is fail, corresponding red LED will on. Voltage limit protects your loads from low and high voltages So no need to connect the computer on production testing

You can put your notes here Enter Testing Person Name Select if you wants to open the pdf after creation Click here to generate PDF Notes :- Features in Demo and User Version Currently Demo version has 15 Channels. User version will be available with 16 Channels. Demo versions has low accuracy. Accuracy will be increased at User Version. Display size of Demo Version is 16X2. User Version will be available with 16X4 LCD. Demo version is started from its initial stage when it goes off. In user version it will start from its previous state. If required, SSR Can be replaced by Contactor. But we recommend to use SSR . Demo version has Green LED for load and Yellow LED for Fail Indication. In user version Yellow LED will be replaced by Red LED.
