Encore
Current to Voltage Transducer / Shunt
OVERVIEW
Verivolt Encore is part of the Verivolt family of current to voltage transducers designed to measure
isolated and ground currents. The main focus of the Encore family is to ease and accelerate measuring the output current from low voltage current sources as well as isolated current transformers
(CT). Particular attention was paid on providing a solution that minimizes cost and improves overall
performance on distributed systems such as substations, building monitoring, power distribution
systems, etc. The Encore series covers the ranges of ±0.1A, ±1A, ±2A, ±3A, ±4A and ±5A with customizable bandwidth of up to 40kHz and 0.2% accuracy

DESCRIPTION
Verivolt Encore 5c operates as a current to voltage shunt that
generates a ±100mV range signal for it’s nominal input current
range. This signal can then be processed by a computer based
measurement platform. In conjunction with the EasyConnect family, the Encore is the ideal solution for high channel density applications

Due to its compact size and shape, the Encore can be easily
mounted anywhere between the signal source and the data acquisition system. The versions up to 5A may even be used inline
with the cable and not require any mounting at all.
All can be secured to fixtures using cable ties.

DANGER
THIS SENSOR IS NOT A SAFETY DEVICE AND IS NOT INTENDED TO BE USED AS A SAFETY DEVICE. This sensor is designed only to detect and read certain data in an electronic manner and perform no use apart from that, specifically no safetyrelated use. This sensor product does not include self-checking redundant circuitry, and the
failure of this sensor product could cause either an energized or de-energized output condition, which could result in death, serious bodily injury, or property damage.
