Datasheet

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.

The LAN interface for PFR-100 is Ethernet port. PFR-100 also has a built-in web server and intuitive user interface. 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 their

operating PFR-100s in the lab from your home. The outputs of PFR-100 series can be monitored including OVP, OCP, UVL; and

the system information 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, Bleeder circuit control, OCP, delayed

time for output voltage and Buzzer settings.

The PFR-100 series provides special functionalities to meet test requirements for different load's characteristics. The CC priority

mode can be applied for DUTs with diode characteristics to prevent DUT from being damaged by inrush current. A slow rise time

for voltage can also protect DUT from inrush current, especially for tests on capacitive load. When power is off or load is

disconnected, the activation of Bleeder circuit control will allow the bleeder resistor to consume filter capacitor's electricity.

Without the bleed resistor, power supply's filter capacitor may still have electricity that is a potential hazard. For automatic testing

equipment systems, the bleeder resistor allows PFR-100 series to rapidly discharge to prepare itself for the next operation.

C.V/C.C PRIORITY MODE

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.

Under C.C priority mode, inrush and surge voltage

are effectively restrained.
