Product Description

2-ch, high voltage amp, high isolation per channel, 1M samples/s, 2V to 1kV F.S.

High Voltage Input module records direct AC power line or DC power source up to 1000Vp-p.  Some application requires faster than 50/60Hz AC signal can also be recorded on the GL7-HV using the maximum 1MS/s (1µs) for laser, IR, and blue-ray signals that may encounter high voltage values.  There is more need to measure generator/inverter based system for automotive and aerospace market as well as electrical and heavy industrial equipment for performance quality and product longevity monitoring.  GL7-HV with its real-time RMS measurement capability allows true-RMS monitoring for manufacturing with investments in high priced heavy equipment.
