MPAS 120/230-4K AC/AC Switching Transformer 220V

 AC/AC Switching Transformer 220V


Product Model: 


MPAS 120/230-4K

Product Description: 


MPAS (AC/AC Switching Transformer) is a type of high efficient transformer developed by adopting a high-frequency switching technology.


Product Introduction:

The MPAS AC/AC Switching Transformer is used to galvanically isolate the yacht's power system from shore power systems. This device uses high frequency electronic switching technology to efficiently transfer power though a compact and lightweight isolation transformer. Using the MPAS transformer in a yacht can effectively prevent galvanic corrosion of metal parts of the yacht's hull and attachments such as through-hulls and ensure a safe application of a marine power supply system.

Application Field:

For the power supply system of yachts and boats.

Product Features:

● Adopt an advanced high-frequency switching conversion technology to provide a reliable isolated power supply to electrical appliances.
● Wide input range, high adaptability for power grids.
● High efficiency & high power density.
● Multiple built-in protection functions including OVP, OLP, OTP, and SCP.
● Support for parallel operation with multiple MPAS units to achieve for power capacity expansion.
● Intuitive and user-friendly interface, simple to operate, and have an option for using LCD monitoring panel for performing touch-screen quick operations.
● Support for NMEA 2000 communication protocol, and remote monitoring.

● Wall-mounted installation, simple to install and easy to maintain.
