The 5725A Amplifier enhances the 5700A Calibrator in the ac voltage, ac current, and dc current functions. The 5725A operates under complete control of the 5700A through an interface cable supplied with the 5725A.
-
Enhancements to 5700A ac voltage output capability provided by the 5725A are as follows:
-
Frequency limits at higher voltage increase to 100 kHz at 750V, 30 kHz at 1100V
-
Load limits are to 70 mA for frequencies above 5 kHz, and to 50 mA for frequencies less than 5 kHz
-
Capacitive load limits are increased to 1000 pF
-
Model 5725A operating functions and ranges are as follows:
-
AC voltage: 220 to 1100V rms up to 70 mA (50 mA < 5 kHz), 40 Hz to 30 kHz; 220 to 750V rms up to 70 mA, 30 kHz to 100 kHz
-
DC current: 0 to ±11A
-
AC current: 1 to 11A rms, 40 Hz to 10 kHz
-
100, 110, 115, 120, 200, 220, 230, or 240 Vac ±10%; 47-63 Hz operation
