General Specifications

Voltage: 0-18V

Current: 0-300A

Circuits: up to 5

Data Sampling Rate: 1 sec

Input Power Supply: 3-phase, 50/60 Hz

Accuracy: 0.5% of FS*

Network: Coax

*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.

The LCRN can charge constant current with or without a voltage limit. If a voltage limit is set, then the unit will charge constant current until the voltage limit is reached. It will then change constant potential with the charge current tapering to maintain the preset voltage. Three silicon controlled rectifiers and five diodes in conjunction with an inductive capacitive filter provide the regulation of the unit.
