This high-voltage power supply system allows the BlueROV2 to be powered through the tether, allowing it to operate indefinitely and eliminating the need for batteries! It’s designed with safety as the highest priority and comes with everything needed to retrofit your BlueROV2.
The System comprises of three parts. Topside power supply, replacement cable with Power lines inside and Subsea power bottle.
The Topside Power Supply Unit
The Topside power supply unit is built into a portable case. Inside it has a high-voltage power supply, a built-in Fathom-x interface board and a ground fault interrupter (GFI) for safety. It has a built-in laptop shelf that minimizes the table space needed to operate the ROV.
Since it includes a Fathom-X communication board, the topside unit connects directly to the laptop via a USB cable and there is no need to use the FXTI Box.
The ROV Power Supply Enclosure
On the ROV, the battery enclosure is replaced with the ROV Power Supply Enclosure, which contains a power supply that converts the 400 volt power down to the 15 volts needed by the ROV. It comes with a pre-installed power cable and a tether signal cable with penetrators, making it a drop-in replacement for the original battery tube. The enclosure is equipped with two wet-mateable electrical connectors that allow the ROV to be connected and disconnected from the tether cable.
The High-Power Tether Cable with Connectors
The High Power Tether Cable is specially designed for this application and has five twisted pairs of varying sizes for each function. Two 23 AWG pairs are used for the primary isolated power transmission while a 24 AWG pair is used for a solid connection to the earth ground to help detect any safety faults. One 26 AWG pair is used for the primary Fathom-X communication and another is available for auxiliary devices such as the Water Linked Analogue Locator.
The tether is available in 125m and 250m lengths. It is not compatible with the Fathom Spool at the moment.
