Converters(CN-SF/D)
The TECNED CN(SF/D) converter series is available with input and output voltages ranging from 24Vdc to 220Vdc nominal. The CN(SF/D) converters are available in capacities from 10 to 400A.
CN (SF/D) converter can be supplied as standard or fault tolerant systems within a single enclosure to meet customer requirements for safety and reliability.
The CN-SF (software free) model is a strictly analog converter available with natural convection and forced air cooling depending on rating. Standard features include input high/low, output out of limits and general alarm, input and output V/A metering, potential free contacts and input/output fuse monitoring.
The CN-D model includes an additional digital controller with LCD display that shows the systems current state of operation and system values, allows setting of system parameters and includes event and alarm logs.
