Power cable

The radome radar systems are intended for use on ships’ DC power systems operating in the 10.7 to 32 V DC range (that is, 12 V and 24 V systems, not 32 V systems). A 1.5 m (5 ft) power cable is supplied (with the display unit) for connecting the ship’s DC power to the radar scanner via the display unit. Refer to the HSB Series Display Owner’s Handbook for details on connecting this cable. This section provides details for extending the length of the power cable.

If a longer power cable run is required, use the supplied power cable to connect to the display unit. Then use a suitable connector block to connect the free end to the extension cable. The supplied power cable has a cross-section of 2.0 mm2.

Note: For vessels with 24 V power systems, the power cable may be extended by up to 20 m using a wire gauge of 1.5 mm2 (AWG 16) or greater, irrespective of the inter-unit cable length.

For vessels with 12 V power systems, longer power cable runs may require larger wire gauges to minimize any voltage drop in the cable. The scanner type and the length and type of the inter-unit cable (see tables) also affect the wire gauge required for the extension power cable. In order to determine the correct supply cable size if the power cable must be extended, estimate the length of cable between the ship’s main power source and the connector block, and then select the wire size indicated by the distance and inter-unit cable in the appropriate table following.

For example, you might have a 24" scanner, with 20 m between the scanner and display unit, that you plan to connect by extending the supplied 15 m heavy inter-unit cable with a 5 m extension cable. In addition, your 12 V power supply might be 10 m from the display unit, requiring an extension of 8.5 m. To determine the wire gauge required for the power cable extension, refer to the table for the 24" scanner, go to the row labelled 15 m Heavy + 5 m ext, and read across until you come to a maximum cable length greater than 8.5 m. This is the 10 m entry, in the column for 4.0 mm2 wire gauge.
