Introduction
The Keithley Models 2380-500-15/2380J-500-15/2380-120-
60/2380J-120-60 programmable high-precision DC electronic load
instruments support constant current (CC), constant voltage (CV),
constant resistance (CR), constant power (CP), and transient
operating modes. Its power ranges from 200 W to 250 W. The
resolution of its voltage and current are 0.1 mV and 0.01 mA. Its
adjustable current rise and fall times range from 0.0001 A/µs to 2.5
A/µs. Its measurement speed of voltage and current reaches up to 50
KHz. The load can be controlled externally from 0 through 10 V
using analog interfaces. It is equipped with built-in ports of RS232,
USB, and GPIB. The load also provides special LED mode to
conduct LED power supply test by simulating LED current.
The models are listed in the table.
