Fluke 5725A 量程扩展放大器

Fluke 5725A放大器增强了5700A系列多功能校准器的交流电压，交流电流和直流电流功能。 5725A通过5725A附带的接口电缆完全控制5700A系列校准器。

Enhancements to 5700A/5720A ac voltage output capability provided by the 5725A：

▪  Frequency limits at higher voltage increase to 100kHz at 750V, 30kHz at 1100V

▪  Load limits are to 70mA for frequencies above 5kHz, and to 50mA for frequencies less than 5kHz

▪  Capacitive load limits are increased to 1000pF

Voltage output from the 5725A is available at the 5700A Series Calibrators' front or rear binding posts. This eliminates the need to move cables during a procedure that requires amplified as well as standard calibrator outputs.

The 5725A front or rear panel OUTPUT binding posts are only for current output. Extended-range ac and dc current is supplied through them. Since most meters with a high current range use a separate high current input terminal, this configuration normally eliminates the need to move cables during a procedure. If a single-point current output is needed, the 5700A Series Calibrator can be configured to source all current outputs through the 5725A binding posts.

Model 5725A operating functions and ranges:

▪  AC voltage: 220V to 1100V rms up to 70mA (50mA < 5kHz), 40Hz to 30kHz; 220 to 750V rms up to 70mA, 30kHz to 100kHz

▪  DC current: 0A to ±11A

▪  AC current: 1A to 11A rms, 40Hz to 10kHz
