Description
The 5220A Transconductance Amplifier allows for the calibration of AC or DC meters and shunts and current functions of digital multimeters that measure up to 20 A. A known input voltage of 1 to 20 volts produces a known output current of 1 to 20 amps. The 5220A is designed to be controlled by the 5700A or 5100B series calibrators but may be driven by any other voltage source. Features and Specifications:
  • Transconductance: 1 siemens (1 A per volt)
  • Output range: 0 to 20 A dc or rms ac
  • DC accuracy: ±(0.025% of output + 1 mA)
  • AC accuracy: ±(0.05% of output + 1 mA) from 30 Hz to 1 kHz, and ±(0.05% of output + 1 mA) x f from 1 kHz to 5 kHz, where f is frequency in kHz
  • Short-term stability dc: output changes less than ±(0.005% + 200 µA) in 10 minutes, with constant line, load, and temperature
  • Short-term stability ac: output changes less than ±(0.01% + 500 µA) in 10 minutes, with constant line, load, and temperature
  • 100, 110, 115, 120, 200, 220, 230, 240 Vac +10%; 50-60 Hz operation
  • Weight: 50 lb; Size: 178 mm (7.0 in)H x 432 mm (17.0 in)W x 559 mm (22.0 in)D
