The GW Instek PFR-100LGL DC power supply has a longer life cycle because of its fanless structure. The fanless structure allows users to focus on their experiments and tests in a quiet environment. The PFR-100LGL has a maximum output voltage of 50V (at 2A) with rated 100W. The PFR-100LGL also has a GPIB and LAN interface.

Notes:
*1: At 85 ~ 132Vac or 170 ~ 265Vac, constant load.
*2: From No-load to Full-load, constant input voltage. Measured at the sensing point in Remote Sense.
*3: Measure with JEITA RC-9131B (1:1) probe
*4: Measurement frequency bandwidth is 10Hz to 20MHz.
*5: Measurement frequency bandwidth is 5Hz to 1MHz.
*6: From 10%~90% of rated output voltage, with rated resistive load.
*7: From 90%~10% of rated output voltage, with rated resistive load.
*8: Time for output voltage to recover within 0.1% + 10mV of its rated output for a
load change from 50 to 100% of its rated output current.
*9: For load voltage change, equal to the unit voltage rating, constant input voltage.
