Manual 2101 Datasheet

The Valhalla 2101 is a single-phase digital power analyzer boasting twin high resolution digital displays, DC to 50 KHz frequency responses, true power measurement, true RMS voltage and current and built-in peak overload indicators.

The wideband direct-coupled, front-end design of the 2101 permits it to make accurate power measurements, even in the most difficult applications. Switching power supplies, SCR controlled circuits and pulsed DC devices are just a few of the applications requiring the true power measurement capability of the Valhalla 2101.
