M192 Programmable AC/DC load

M-192 is accurate resistance power load with adjustable output in range 15.000 Ohm to 300 kOhm. Load can be used up to 3000W and 250 Vrms. Frequency range is from DC to 10 kHz. Load is organized as a set of power resistance segments switched using relays. Load is especially suitable for automated testing systems. Instrument is equipped with RS232 interface as standard, IEEE488 interface is available as option.

Two versions of the load are available:

M-192 basic version offers 60 fixed resistance values in range 15 Ohm to 4700 Ohm.

M-192A full version has continuous resistance range 15.000 Ohm to 300 kOhm and internal voltmeter
