The ISOPOWER is specifically designed as a power source for the ISOPORT and ISONODE network modules, the ISOPOWER provides a 24VDC output for upto 32 output or inlet modules. The ISOPOWER provides the facility to connect three separate DMX512 inputs. It then buffers and isolates them, and provides three DMX512 outputs. When used as a standalone unit the ISOPOWER provides the isolation between the inlet modules and the outlet modules. Outputs can then be fed through Multisplit data splitters. Installing a distributed network of DMX512 inlet and outlet modules enhances security against equipment failure rendering the total system useless. However a distributed system will only be totally reliable if the power supply to the individual modules can be guaranteed. For this reason the ISOPOWER is short circuit proof and has the facility to be linked to a second ISOPOWER to provide full redundancy. An auto-fault detection circuitry detects a power failure in the first unit and automatically switches to the back-up ISOPOWER. A front panel button allows you to manually switch the ISOPOWER into either active’ or ‘standby’ mode. Front panel indicators display essential information such as data present on any of the three incoming DMX512 streams; internal power supplies’ status (including ‘fault’ indicator); cooling fan operating; and ‘active’ or ‘standby’ mode. The ISOPOWER can be connected to the ‘outside’ world in a number of variations. The basic unit has the wiring for the three DMX512 inputs and the three DMX512 outputs on a computer style DB25 connector. The DC out is provided on a separate power connector. A rear panel switch allows the individual termination of each DMX512 input. The system wiring can then be wired directly to a mating DB25 connector or to an optional ISOPOWER KRONE termination panel.
