The 2558 is a precision, stable AC voltage and Current source. Output voltage or current set using front-panel dials is controlled by digital signals through photo-couplers and microprocessors, and displayed on a red 5-digit LED.
Features:
+/-0.08% accuracy
1 mV to 1200V in 6 ranges, 1mA to 60 A in 4 ranges
Frequency ranges - 50, 60, 400Hz or 40 to 500Hz continuously variable
External oscillator can also be used on 40 to 800 Hz frequency ranges.
Overvoltage and overcurrent protection
Sweep mode
Large output capacity - 30V max. on 100 mA range, 0.5A max. on 1 V range
% Deviation readout
Output divider
Remote control and programming using IEEE-488 interface
