General Specifications

Voltage: 0-18V(other voltages available)

Current: 1µA-300A (2700 in parallel)

Circuits: up to 96

Network: Ethernet

Accuracy: ±0.1% of FS*

Data Sampling Rate: up to 10mS

*Accuracy values are conservative assuming operation will be through the standard temperature range of 0-40˚ C and RH from 10-90% (non-condensing). Units calibrated and maintained in a temperature and humidity controlled environment can expect an accuracy of 0.02-0.05%FS.

Overview

The MCV is a low-current life cycle test system for development of primary and rechargeable batteries in various chemistries. Operating from a common microprocessor, multiple circuits in the MCV module can run individual test programs.  Additionally, the MCV is designed and built for ease of maintenance and service.  The modular construction means that most subassemblies, large or small, remove easily for service outside the cabinet and fast replacement.
