PRPT-16

Key Features

• Heavy Duty Dual Relay Capable of Switching at Loads of more than 24 Amps
• Automatic and programmable Switching
• 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. Semiconductor-based equipment is tested at these extreme voltages and that too 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 the easily customizable switcher and 16 channel wattmeter. You only need to provide the power/Voltage as per your requirement and initial configuration.

Required Ruggedness Test for LED Drivers

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.

Display Features

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

LEDs Indication

PRPT-16 has 16 set of green and red LEDs load pass/fail indication. If the load is connected to any channel related channel green LED will ON. If Load is failed than related red LED will ON. Load limits can be set using the 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 a set button is used to enter the setting.

Rotatory Switch

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

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 switching cycle.

For example, we have to do the 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 the above graph.

For reporting, we can add some information on the testing product as below –

We can also generate a pdf report based on the filled information in the software. This data will transfer to PRPT-16 and can be run on prog mode.
