Programmable Range Power Tester

Example LED Driver’s Specification - INPUT : 170-270 V~0.2 A, 50-60 HzOUTPUT : 5 V 1 AEFFICIENCY - 80%

output wattage ~ 4 Watt

170 V

270 VN

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

16 Channel output/Measurement

Here you can give timing for switching of relays.This will be transferred toPRPT-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

D1 8.3

In above D14 has two Drivers of 4.1 W So Total W = 4.1*2 = 8.2So 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 canProduce more voltage or increase the wattage and other can beproduce 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 3.2wThen 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

Software Snapshot of PRPT-16

Enter Model No and Version for which you are setting Limits.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

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.

Proposed Selector Switch for Changing Test Modes

Rapid Mode

Auto Mode

In this mode no relay will be ON.

In this mode Relay 1 will be ON

In this mode Relay 2 will be ON

In this mode user defined Cyclic Switching will ON

In this mode Automatic Switching of Relays with time period of 2 Seconds will ON

We are also proposed to use Selector Switch for changingthe Test Mode.
