Complete LED Driver Testing with DTM-1

Complete LED Driver Testing with DTM-1

     

DTM-1 is AC-DC converter testing instrument with harmonics. It is made to increase the quality of LED drivers/SMPS/AC-DC Converters at production.

It tests both AC and DC parameters with harmonics and efficiency.

AC Parameters are –

Voltage, Current, Watt, PF, Frequency
Vthd, ATHD, Harmonics 1st to 55th

DC Parameters are –

Voltage, Current, Watt, Efficiency

ScreenShots and Details on DTM-1

Main Page display

Main Page – Includes AC-DC parameters which are sufficienct for production testing.

AC parameters only Voltage current and THD

AC Parameters Page – Voltage , Currnet Watt, Frequency, VTHD,ATHD and NET THD

DC parameters

DC Parameters Page: Voltage, Current, Watt, Efficiency

DTM-1 has internal memory to save Production report without pendrive or computer.

It can store upto 4000 Tests in its internal memory.

Backing up on Pen drive

Saved data can transfer to pendrive for backup.  Above page shows to transfer the ONBoard data (Internal Memory) to the pendrive.

There are Three options as user can save last unbackuped test or previous 1000 Tests or previous 4000 Tests from the ONBoard internal memory to pendrive.

Some other features are –

  1. Pen drive based production and data logging with Serial No.
  2. Internal Real Time clock for logged data
  3. Software Interface with Real time values and other PC based testing facility
  4. Log on connect mode for automatic testing of led drivers with serial no and datetime stamp.
  5. LED Driver test report in pdf format.

FAQs –

Q1- What parameters it shows on main page?

Ans- It shows AC voltage, Current, Watt/PF, Current THD% , DC Volts, Current, Watt and Efficiency on the main page.

Other parameters are available by pressing the page button.

Q2- What are the  harmonics level it measures?

Ans-  It measures upto 55th harmonic of voltage and current.

Q3- How many product models i can save in DTM-1?

Ans- It saves upto 25 models in its internal memory. You can overwrite if you require.

Q4- Can overwrite any model or limit in DTM-1?

Ans -Yes. You can change/overwrite models saves in DTM-1 using DTM-1 software.

Q5- If pendrive is provided then why do i require internal memory?

Ans – In ternal memory is useful for historical data as well as it makes sure you have a backup.

Typically, You would like to wrok with internal memory and a superwiser could take data using a pen drive and process it further on his computer.

Q6- Can i transfer the production data from DTM-1 internal memory to pendrive.

Ans- Yes. DTM-1 has option to transfer the datapoints to the pendrive. You can transfer last 1000 data points or 4000 data points to pendrive.

Q7- What is the format of pendrive data?

Ans- Data saved in pendrive is in csv format which is easily openable in excel or notepad.

Q8- How much data can i save in the pendrive?

Ans- A  pendrive can save millions of data points.

Q9- What is maxmium memory of pendrive it support?

Ans – It supports upto 16 GB Pendrive for logging.

Q10- Can i set the display refresh rate in DTM-1?

Ans – Yes. You can change the display referesh rate from 0.5 seconds to 2 seconds in the DTM-1.

Q11- Can i set and autochange the serial number in production testing?

Ans – Yes. You can edit the serial number in DTM-1.

Q12- For each Led driver we take 3 tests at voltages of 120Volts, 230Volts, 270Volts

Ans – You can use Grouped Test and select value 3 for it in setting menu. You will get auto increment of serial number with A/B/C.

For example 3 Consecutive readings with 2893A, data, 2893B, data, 2893C, data with auto increment option.

Q13- What input source should i provide?

Ans – Normally you can work on AC power Supply with Variac. If Input THD at your  location is high then you may provide a sine wave UPS/Inverter.

Q14- I want to do testing without touching DTM-1. Is there any option to do this in DTM-1?

Ans- Yes. DTM-1 has Log on Connect facility. You can set the LOC ON/ OFF time and serial number once. Then You can do testing without touching DTM-1. It will log the data and increment serial number automatically when any load connect and disconnect to it.

Q15- Is DTM-1 indicate the PASS/FAIL status on testing?

Ans – Yes. DTM-1 indicates FAIL result by blinking status LED.  It also dipslay PASS/Fail on LCD Display. Buzzer facility is provided for PASS/FAIL.

Q16- Can i do datalogging in DTM-1?

Ans – Yes. DTM-1 has data logging facility on pendrive. You can set the data logging period and set the application as data logging.
