YS118C Multi-function Power Source

YS118C is an intelligent multi-function power source for calibration of AC/DC voltmeter, AC/DC current meter, frequency meter, phase meter, AC/DC power meter and electrical quantity transducer. It is characterized by phase angle closed loop, voltage closed loop, current closed loop so as to ensure low shift and year stability.

Description

APPLICATION

YS118C programmable multi-function power source is an intelligent power standards developed in 2006. Featured with high stability, easy operation, it is an ideal upgraded product for calibration of “AC/DC voltmeter, AC/DC current meter, frequency meter, phase meter, AC/DC power meter and electrical quantity transducer”. The multi-function power source is characterized by phase angle closed loop, voltage closed loop, current closed loop so as to ensure low shift and year stability. Besides, it is equipped with full duplex RS232 interface and GPIB interface which in compliance with IEEE standard 488.2 for easy connection with PC, suitable for auto test system.

FUNCTIONS

  • Phase angle closed loop, voltage closed loop, current closed loop to ensure low shift and year stability.
  • High resolution up to 20ppm (0.002%), 5 1/2 output value, set as you desire.
  • Can calibrate D26 meter, voltage range output load current max. up to 800mA.
  • New self-calibration function, any calibration point can be used right after calibration.
  • Can automatically test error of each point of meter under test.
  • Error of meter under test can be displayed between “reference error” and “relative error”.
