Use a single, 24V DC power supply, such as catalog number 2711P-RSACDIN, to power PanelView Plus terminals with a nonisolated DC power supply. Using a separate, isolated, and ungrounded source with each terminal prevents ground loop currents from damaging the product.
The power supply of the isolated DC PanelView Plus 700...1500 terminals lets you power multiple terminals from one DC power source without creating a ground loop. The illustration below shows one 24V DC power supply providing power to a DC motor and a nonisolated PanelView Plus terminal.
The design is to comply with the requirements for Voltage Variations for DC Distribution Systems as per 4-8-3/1.9 of the Marine Vessel Rules. The applicable table is listed below for convenience. Any harmonics created within AC systems is to be within the limits specified in 4-8-2/7.21 of the Marine Vessel Rules.
There are strict requirements on power density, thermal performance, eficiency and core rail tolerance, including DC accuracy and load transient response (AC tolerance), as well as many other specifications such as ripple and electromagnetic interference. A wide variety of power solutions exist for non isolated DC/DC rails.
