Pure sine wave inverter used in boats for converting DC into AC power

Marine inverter is an industry-specific inverter developed by our company for new energy ships to convert the DC power on board into AC power for various electrical appliances on the ship. This inverter adopts power frequency isolation design. For special requirements such as small installation space and irregular installation space of industry users, performance parameters and installation dimensions can be customized to meet various compact installation space and electrical heat dissipation requirements.

Applications

Marine inverters are widely used in various electrical appliances on ships, including ship electrical equipment, communication equipment, navigation equipment, etc.

Features

Marine inverter adopts Mitsubishi's sixth-generation IPM module, with stable performance and a designed service life of over 15 years.
Dual-mode start option allows for voltage reduction start and frequency conversion start settings through the screen.
Pure sine wave output comes with a transient response time of less than 50ms.
Isolation transformer design enables complete electrical isolation between input and output, with plastic shell circuit breakers on both input and output.
Low input ripple current is suitable for various DC power inputs.
This pure sine wave inverter has passed European CE (EMC and LVD), ISO9001, and CCS certificates.
