Universal calibrator H4-20A

Calibrator is designed for reproduction of constant and alternating (in the frequency range from 40 Hz to 2,5 kHz) electric voltage, constant and alternating (in the frequency range from 40 Hz to 2,5 kHz) electric current, frequency of alternating (in the frequency range from 40 Hz to 2,5 kHz) electric voltage, simulation of electric power (with simultaneous reproduction of electric voltage and electric current). The calibrator is able to work both autonomously and as part of automated measurement systems with RS-232 and ETHERNET interfaces. The device in the mode of reproduction of voltage and DC current provides polarity reversal on potential terminals. The device has protection against overloads, short circuits on the output and load interruption. The device has manual (from the front panel) and remote (via RS-232 and LAN) control of output parameters. The device allows continuous operation under working conditions for at least 16 hours
