Isolation Transformer

- Converts shore power voltage to a higher, lower or equal value to ensure that there is galvanic isolation between the shore power connection and the onboard electrical system. This prevents corrosion and increases safety.

Inverter

- Converts 12, 24 or 48 volt battery power to alternating current at 230 V/50 Hz (or 120 V/60 Hz). This allows appliances such as computers, microwave ovens and TVs to be powered without the need for a grid connection or generator

IEC Approval

- The International Electrotechnical Commission (IEC) is headquartered in Geneva, Switzerland, and develops general standards for the safety of electrical components and equipment. Although it proposes standards, the IEC is not responsible for their enforcement, which is usually carried out by independent test laboratories.

IP Protection Rating

- The code that defines the IP protection degree consists of 3 digits. The first refers to solid particles, the second to the liquid medium and the third to resistance to mechanical impact (no longer used). The code can be expressed, for example, in the following ways: IP 01, IP 21, IP 42, IP X1, IP1X

First digit:

0 - Not protected
1 - Protection against solid objects with a diameter of 50 mm or more
2 - Protection against solid objects with a diameter of 12.5 mm or more
3 - Protection against solid objects with a diameter of 2.5 mm or more
4 - Protection against solid objects with a diameter of 1.0 mm or more
5 - Dust protection
6 - Dustproof

Second digit:

0 - Not protected
1 - Protected against vertically falling drops
2 - Protected against drops falling vertically with body inclined up to 15°
3 - Protected against water spray
4 - Protected against splashing water
5 - Protected against water jets
6 - Protected against powerful jets of water
7 - Protected against temporary immersion in water of up to 1 meter for 30 minutes
8 - Protected against continuous immersion in water
9 - Protection against immersion (for 1 m) and pressure resistant.
9K - Protected against water from steam jets and high pressure

IP Ingress Protection

- IP code or ingress protection code is defined by the International Electrotechnical Commission (IEC) under the international standard IEC 60529 which classifies and provides a guideline to the degree of protection provided by mechanical casings and electrical enclosures against intrusion, dust, accidental contact, and water. It is published in the European Union by the IEC as EN 60529.
