MORE DETAIL CLOSE

The PFR-100 series, a small and high-performance programmable D.C. power supply, adopts natural convection design to dissipate heat. The fanless structure allows users to focus on their experiments and tests in a quiet environment. Fanless power supply will not suck in dust and foreign objects, therefore, PFR-100 series has a longer life cycle compared with that of power supplies with fan.

 

The PFR-100 series is a power supply with a five-fold rated power that allows users to self-define voltage and current under rated power conditions so as to satisfy them with wider voltage and current operational ranges. PFR-100 series, with rated 100W, provides two models: PFR-100L- maximum output voltage of 50V (at 2A) or maximum output current of 10A (at 10V); PFR-100M maximum output voltage of 250V (at 0.4A) or maximum output current of 2A (at 50V).

 

The PFR-100 series provides front and rear panel output terminals. The front panel output terminal helps users shorten test lead replacement time while conducting adjustment on front panel's function keys. The rear panel output terminal facilitates an easy wiring operation for rackmount assembly. 3U height, 70mm width and 2.5KG in weight have greatly elevated PFR-100 series portability. Furthermore, the multi-drop mode allows users to control up to 31 PFR-100 series without using switch/Hub that help users save the equipment cost.

Applications and Solutions - The setting of Test Script

Test Script Setting Procedures: (Using a PSW as an example):

1. Download t001.csv and t001.tst from GW Instek website

http://www.gwinstek.com/upload/media/application/TheSettinOfTestScript/t001.zip

 

2. Save t001.csv and t001.tst to your USB’s root directory and confirm the saved file names are identical in your USB flash drive

 

 

3. Open t001.csv provided by GW Instek and edit output voltage, current, time, cycle, etc. for step1~step9. Please refer to the following chart. For cycle setting, first of all, set the step numbers for Start and End. Start and End should be placed corresponding to the step positions.

 

 

 

After filling the Excel chart with the parameters, users can quickly obtain a sequential power output as shown below.

 

From the above output example, each step is a setting and there are 9 steps to make up a cycle. The set cycle was repeated for two times.

 

Settings for power supply: (For demonstration purpose, this example only planned 9 steps, please see Test Script features below for its full capability.)

 

Features of GW Instek Test Script:

Setting: Capable of editing up to 20,000 settings

Cycle: Capable of setting 1 billion or infinite cycles

Duration time: Each setting can be set from 50ms to 20 days

 

Settings for power supply:

Step 1 Set output Off for two seconds
Step 2 Set 80V/ 7A output for 10 seconds
Step 3 Set 20V/3.5A output for 3 seconds
Step 4 Set 75V/8A output for 5 seconds
Step 5 Set 30V/10A output for 2 seconds
Step 6 Set 45V/10A output for 4 seconds
Step 7 Set 50V/10A output for 2 seconds
Step 8 Set 10V/10A output for 1 second
Step 9 Set 70V/20A output for 5 seconds. Determine whether the cycle number reaches 2.

 

(End Test Script if the cycle number is 2. If the cycle number is less than 2, repeat step1~step9.)

 

Test Script Parameter Definition:

i. OVP: over voltage protection setting. MAX: Maximum value by default;MIN: Minimum value by default

ii. OCP: over current protection setting. MAX: Maximum value by default;MIN: Minimum value by default

iii. Set Bleeder to 1 to activate bleeder control。(This function is to assist DUT to quickly discharge) Set Bleeder to 0 to deactivate bleeder control
iv. IV mode:
CVHS: Set PSW under CV priority mode, voltage rising and falling are at the fastest mode (slew rate setting for voltage and current is invalid)
CCHS: Set PSW under CC priority mode, current rising and falling are at the fastest mode (slew rate setting for voltage and current is invalid)
CVLS: Set PSW under CV slew rate control mode, voltage rising and falling are operated by settings。
CCLS: Set PSW under CC slew rate control mode, current rising and falling are operated by settings。
Cycle: Set the number of cycles (To execute infinite cycles please set the number of cycles to 0)

 

4. The following dialogue box will appear when you save or close the file. Please click “yes”to maintain this format.

 

 

5. After saving the file, please insert USB to the USB port on the front panel of PSW and wait for 5 seconds. (MS appearing on the display represents USB has been read)

 

6. Press test key on the front panel of PSW to enter Sequence function settings.

 

 

7. Use voltage knob to select T-02, then use current knob to select desired memory location (1~10) and press voltage knob to save the file to PSW.

 

Note: If .csv file name is t001 please select memory location(number) 1. If .csv file name is t002 please select memory location 2 and so on.

 

 

8.Use voltage knob to select T-01, then use current knob to select desired memory location (1~10) and press voltage knob to confirm execution setting. Press OUTPUT key, PSW will then output the previous edited settings.

 

9. Press voltage knob and then the following display will be shown to represent it is successfully entering the execution stand-by display. Press “output” to initiate operation. To pause operation, press “output” again. To resume operation, press “output”. To terminate operation and exit Test Script, press “Test”.

 

 

 Note: If there is error messages as shown on the following displays please follow “Error Messages and Solutions”to amend t00x.csv file.。
(For example: Error 93→_SEQ_ERR__OCP_TOO_SMALL.) OCP setting is too small that is beyond the specifications. Settings should be within the specifications.)
