General Specifications

Voltage: 0-72V

Current: Up to 3000A; up to 12,000A with external PCC

Power: up to 90kW; up to 360kW with external PCC

Circuits: 1

Network:  Ethernet

Accuracy: ±0.1% of FS*

Duty Cycle: 100%

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

Bitrode’s model DTV is a high current discharge testing system designed for cold crank testing and discharge capacity performance testing.  The DTV also supports data collection on a full range of external inputs for specific laboratory requirements including: thermocouples, PT-100, high impedance voltage, pressure, and specific gravity.
