WARTSILA PDM-20/24V Power Distribution Module

WARTSILA PDM-20/24V is a marine-grade power distribution module built for Wartsila vessel engine control and ship automation systems. This power distribution module supplies fused 24V DC power to sensors, controllers and alarm units onboard. The power distribution module adopts multiple independent output channels with individual fuse protection. The power distribution module supports DIN rail mounting inside marine control cabinets for compact installation.

Branch circuit protection is the core function of WARTSILA PDM-20/24V. Branch circuit protection isolates short-circuit or overload faults on single power branches automatically. Reliable Branch circuit protection prevents local electrical faults from collapsing the whole 24V control bus. Configurable Branch circuit protection protects critical marine automation equipment during continuous vessel operation.

This unit delivers reliable fuse status monitoring for each output channel. fuse status monitoring uses LED indicators to display blown fuse alerts for quick inspection. Robust fuse status monitoring sends collective fault alarms to the ship central monitoring system. Complete fuse status monitoring reduces troubleshooting time in engine room control panels.

WARTSILA PDM-20/24V features redundant 24V DC input design and marine anti-humidity PCB coating. It works under wide temperature range and withstands vibration and shock from seagoing conditions. Each channel has replaceable plug-in fuse for convenient maintenance. Widely used in cargo ships, tankers and offshore platforms for main engine control, alarm management and marine automation power supply. It serves as an essential power protection spare part for Wartsila marine propulsion systems.
