ISC 230B

ISC 230B intrinsically safe mains power supply and signal interface

Design of ISC 230B is specifically for meter set-up with UNIGAS 300. It combines the functionalities of intrinsically safe circuits for LF pulses & serial communication, and explosion safe external power supply for UNIGAS 300. ISC 230B is operated by 230 VAC, but can be supplied by 12 VAC or 12 – 15 VDC as well. Because of this, ISC 230B is ready for use with a solar system.
