Marine ancillary products refer to all marine equipment and devices except the hull, which is an important part of the shipbuilding industry. These products cover a wide range of equipment and systems required for navigation, operation, safety and daily operation of ships. Specifically, marine ancillary products mainly include the following categories: Power equipment: such as ship main engine, auxiliary engine, steam boiler, thruster, shafting, etc., which are the core equipment that provides ship power and power. The main engine of a merchant ship is usually the ship's diesel engine, while the auxiliary power unit is the ship's generator, which provides electrical energy for the ship in normal and emergency situations. Maneuvering equipment: including steering gear, steering gear, autopilot, remote control system, etc., which are used to control the course, speed and attitude of the ship. Loading and unloading equipment: such as cranes, cranes, conveyor belts, etc., used to realize the loading and unloading and transportation of goods.

★With dynamic display of output voltage, current；

★High  precision  regulated  voltage,  output  DC regulated voltage coefficient is less than 1%；

★Output with automatic protection of over voltage or current ,and fan cooling of overheating；

★Wide  range  of  voltage  usage(AC200-240V ， DC24-40V)；

★If the input AC voltage is too low or the power is cut off, the battery power supply will be automatically switched to ensure smooth communication.

Note：

Use any power supply, according to the instrument you are using,  must be professionally configured by what voltage output is required, and  in  the  output  power  range  of  the  power  supply.   Improper  configuration may cause damage to the instrument or burn out the  power supply！

Usage instruction

1.Put the power supply in a dry and horizontal place, and fix the support.    2.Connect the power plug to the AC 220V socket,connect the DC 24V power  supply to the  input  end.  Make  sure  that  the  positive  and  negative

connections  are  not  reversed.  In  the  absence  of AC  input,  the  power supply can be automatically converted to DC input.

3.The output end is connected to the navigation device. Note that the positive and negative connections are not reversed.

4.24Vpower supply：The output voltmeter shows 24V. When there is no load, the ammeter indicates 0A. When there is load, there is current display.  Linear  power  sources  have  a  voltage  drop  of  4V(e.g.  input 24V,output 20V).

5.Automatic power supply：When the input voltage is higher than 29V, the power supply enters the stable voltage, and the output is 24V. When the input voltage is lower than 27.5V, the input voltage is directly output (e.g. the input voltage is 27.5V and the output is 27V).

6.13.8Vpower supply：Output voltmeter indicates 13.8V.

Usage maintenance and warranty scope

Do not place the power supply in a corrosive environment to avoid damage  of  electronic  components.  When   moving  the   power  supply, handle it with care to prevent vibration to cause the internal line contacts loosening.

The warranty period of this product is one year. During the warranty period, the fault (judged by the personnel of the company) arising from the normal use in accordance with the operation instructions will be repaired free of charge. Other artificial damage, the manufacturer will not warranty.
