gle/AC-CTA-100
Rugged AC Current Transducer
Main Features · Rugged construction · Easy installation · Wide temperature range · 400 Hz AC current measurement |
Overview
gle/AC-CTA-100 is a family of rugged AC Current Transducers, based on a toroidal transformer in a potted assembly, directly installable on the current carrying cable to provide a simple method to monitor any AC electrical load.
These transducers are designed for harsh environments applications, typical of onboard flight testing, are optimized for 400 Hz sinusoidal AC current measurement and incorporate a precision low drift resistor to produce a voltage output signal proportional to the input current.
These units are available with different wires length and with four standard output sensitivities, others are available on request.
