PRPT-16

PRPT-16 is a testing equipment used in burn in testing and Ruggedness Testing of LED Drivers and SMPS.

Keywords: Burn In Testing, Ruggedness Testing, Voltage Dips & Interruption Test, IEC-61547/61000-4-5, Endurance Test, Continuous Run Test, Switching Cycle Test

Features :

  1. Heavy Duty Dual Relay Capable of Switching at Loads of more than 24 Amps.
  2. Automatic and programmable Switching
  3. 16 Channel Wattmeter/ Ammeter with settable limits (both High and Low)

Why is it required?

Normally user is expected to provide 230 Volts to a bulb/driver.

But it is specified to work from typically 130 V to 270V. Semicondutor based equipment are tested at these extreme voltages and that to by switching at different voltages and OFF state.

To do this manually you need:

1- A Person or a Relay Switching as per requirement

2- Wattage Meter at each channel and a person to determine if it has gone out of limits.

PRPT-16 helps you automate this task by easily customizable switcher and 16 channel wattmeter.

You only need to provide the power/Voltage as per your requirement and initial configuration.

Here is a typical required Ruggedness test –

You can download above requirement as pdf here

Note: PRPT-16 can be used to perform most of the above-specified tests.

Test 19 to 30  have to be done manually through variac or through customized power sources.

These tests are required by most of the companies for R&D and Quality Testing.

User can input two voltage source. Switching of these voltages can be done using rotatory switch.

Display –

It has LCD display for showing individual loads parameters, settings and switching voltages.

LEDs indication

PRPT-16 has 16 set of green and red leds load load pass fail indication. If load is connected to any channel related channel green LED will ON. If Load is fail than related red LED will ON.  Load limits can be set using Software interface for program mode or can be entered using buttons of PRPT-16.

Buttons

Three Buttons are given. UP/ DOWN are used for scrolling display and set button is used to enter in setting.

Rotatory Switch

Eight step Rotatory switch is provided for easy navigations on testing. OFF step is provided between two steps for safety purpose.

1- Prog – In this mode, voltage switching will done as eneterd by the software.

2- Rapid In this mode, switching  will done as set in PRPT-16 using buttons.

3- SV1-     In this mode, only relay one will active and voltage source connected to this relay will apply.

4- SV2-    In this mode, only realy two will active and voltage source connected to this relay will apply.

5- Off-  No voltage at output

 

Program Mode Feature –

PRPT-16 Saves the step as they completed. So if due to any reason meter goes off then it will start testing from step from where it goes OFF.

Eg. PRPT-16 goes off at step 6 now again when we start the PRPT-16 it will test from step 6 in program mode.

USB Port –

For Software interfacing.

Software –

In Software You can set the required swtching cycle.

For example we have to do 4th test given in the ruggedness testing requirement table.

 So we have to do ON/OFF Testing for 1Hrs at minimum Operating Voltage. Switching Cycle is 10Sec ON and 5 Sec Off.

We have made this cycle in Software as below –

In the above software image user can set the switching timings will relay operations. We have to ON/ OFF the

Switching cycle can be analyzed on above graph.

For reporting we can add some information of testing product as below –

 

We can also generate a pdf report based on the filled information in software.

This data will transfer to PRPT-16 and can be run on prog mode.
