About the DEIF PPU 300
The DEIF PPU 300 is a paralleling and protection unit from DEIF's Multi-line 300 platform, designed for marine use. One controller contains the functions to protect and control a generator or inverter and its breaker, and it can be configured as a genset, bus tie breaker, shaft generator or shore connection controller. Up to 32 controllers form one system with load-sharing sections. The controller is modular: measurement, input/output and communication modules plug into a rack and can be added or replaced on site. DEIF lists the PPU 300 as not recommended for new designs and names the iE 250 Marine as its successor.
What is the PPU 300 used for?
The PPU 300 is installed in the main switchboard of vessels and offshore units, one controller per generator, shaft generator, shore connection or bus tie breaker, where it handles synchronisation, load sharing and generator protection. It suits vessels with several power sources on the busbar, including generators, battery inverters, shaft generators and shore connections.

Before you order
What to photograph or confirm so the right unit is quoted.
Identify the controller type (GENSET, BUS TIE, SHAFT or SHORE), the rack size (R4.1 or R7.1), the installed hardware modules and whether the CODESYS option is fitted. The order code and variant are on the rack label. Send a label photo and, if available, a PICUS configuration backup.
OEM successor to PPU 300
Named by DEIF as the successor. It is an upgrade, not a like-for-like spare: check wiring, I/O and configuration for your installation before ordering it in place of the PPU 300.
Other parts in the DEIF Multi-line 300 family
Listed for reference. They differ from the PPU 300 in rating, supply, interface or function and are not interchangeable with it unless DEIF says so. Match the part number on your unit.
