M192 is accurate resistance power load with adjustable output in range 15 kΩ to 300 kΩ. Load can be used up to 3000 W 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:

M192 -  basic version offers 60 fixed resistance values in range 15 Ω to 4700 Ω.
M192A - full version offers continuous resistance range 15 Ω to 300 kΩ and internal voltmeter
