Keithley 228A
Prog Voltage Current Sourc 100V/10A
Description
This Programmable Voltage Current Source is a precision programmable source with the capacity to sink of source up to 100 watts.
Six ranges accurately regulate voltage or currents as determined by the load.
And because it is two programmable sources in one you get the flexibility for a broader range of test setups, without having to buy separate sources.
It is capable of bipolar source or sink up to a full 100 watts without derating, permitting it to act as a voltage or current supply or as an active load.
Key Points
