Instek PFR-100L w/GPIB+LAN - Fanless Multi-range DC Power Supply

C.V/C.C Priority Mode

Under the conventional C.V mode, inrush current and surge voltage appeared at forward voltage (Vf ) of LED.


 

Under C.C priority mode, inrush and surge voltage are effectively restrained.

Under the application conditions of diode load, conventional power supplies under the C.V priority mode will produce inrush current and surge voltage at turn-on. The PFR-100 series has C.V and C.C priority modes. The C.C priority mode can prevent inrush current and surge voltage from occurring at turn-on to protect DUT.

Adjustable Slew Rate

Adjustable Voltage Slew Rate

Voltage Slew Rate
0.1V~100.0V/sec (PFR-100L)
0.1V~500.0V/sec (PFR-100M)



Adjustable Current Slew Rate

Current Slew Rate
0.01A~20.00A/sec (PFR-100L)
0.001A~4.000A/sec (PFR-100M)

The PFR-100 series can adjust the slew rate for current and voltage. Via setting the rise and fall time of voltage and current, users can verify DUT's characteristics during voltage and current variation. Additionally, slew rate adjustment can mitigate voltage shift to effectively prevent DUT from being damaged by inrush current. This function is ideal for tests such as capacitive load and motor.

Web Server Remote Control Function

Users, via general browsers including Internet Explorer, Mozilla Firefox, or Android cellular phones, can monitor PFR-100's test and measurement anywhere. Users not only can remotely monitor PFR-100 via internet but also remotely observe and adjust your operating PFR-100 in the lab from your home. The outputs of PFR- 100 can be monitored including OVP, OCP, UVL; and system information that can be checked such as unit's serial number, firmware edition, and internet setting. Users can remotely adjust PFR-100 settings, including output voltage/current, the slew rate for voltage/current, Bleed circuit control, OCP, delayed time for output voltage, and Buzzer settings.

Bleeder Circuit Control

The PFR-100 series power supply has a bleeder circuit control which is in parallel with the output terminal. When power is off or load is disconnected, the bleed resistor will consume electricity from the filter capacitor. Without a bleed resistor, the filter capacitor of power could still be charged with electricity that poses a potential danger. In addition, for the ATE system, the bleed resistor allows the PFR-100 series to bleed current rapidly so as to prepare itself for the next operation.

Remote Program Control

(Up To 31 Units Connection)
Provide USB, GPIB and LAN for PC to remote control Master PFR-100. RJ-45 connector on the rear panel can connect up to 31 units. LAN or USB remote control and augmenting slave units by using the multi-drop mode will no longer need any switch/hub that can help customers save equipment costs.
 

External Analog Control Function

The rear panel of the PFR-100 series has an analog control terminal. The external analog control interface allows external voltage or resistance to control voltage and current output, and allows the power supply to output or to be turned on and off. The diagram above shows typical connection methods for external control applications. For more detailed connection information please refer to the user manual.

Output ON/OFF Delay

The Output On/Off delay feature enables the setting of a specific time delay for output on after the power supply output is turned on, and a specific time delay for output off after the power supply output is turned off. When multiple PFR-100 units are used, the On/Off delay time of each unit can be set respectively referring to fix time points. This multiple-output control can be done through the analog control terminal at rear panel or through the PC programming with standard commands.

Using the Rack Mount Kit

The Rack Mount Kits of the PFR-100 Series support both EIA and JIS standards. A standard rack can accommodate 5 units of PFR-100.
