The Associated Research 4040A is a rugged, durable and quality instrument engineered for years of productive service.
120 volts (1 Amp) AC, 50/60 Hz .,Single phase, through 7-1/2 ft .,three conductor detachable line cord, terminated in three prong grounding type plug.
0-3 kV AC, Continuously adjustable. Essentially sinusoidal. Frequency same as input. Maximum current 25 mA (adjustable from .5 to 25 mA). No transients exceeding 120% of peak value .Peak value between 1.3 and 1.5 times RMS value.
Factory preset at 1240 volts with a 1% 120 K ohm load resistor .May be reset if necessary. When properly adjusted, response time is 0 .5 second or less.
Analog, 0-3 kV with 50 volt reading resolution, connected directly across the output terminations. Voltmeter input impedance exceeds 14.7 megohms.
2%of full scale, with 2% tracking.
Failure Detection System:
Audible and visual indication of unacceptable performance and auxiliary relay contacts (SPDT) which transfer when failure is detected. Indicators remain active and conspicuous until reset manually.
High Voltage & Return/Continuity Terminations :
High voltage three prong isolated grounding type receptacle. Also equipped with detachable 5 ft .(grey) high voltage and (black) return/continuity test leads.
