The DEIF HAS-111DG is a dedicated synchronisation and circuit breaker closing module designed for marine power management and generator control applications. Operating within the Marine Control System category, this module performs the critical function of synchronising generator sets before closing circuit breakers, ensuring safe and seamless paralleling of power sources onboard. Precise synchronisation is essential to protecting shipboard electrical infrastructure, preventing surge damage, and maintaining uninterrupted power supply across vessel systems. With a 110VDC supply voltage, relay outputs rated up to 250VAC or 24VDC at 8A, and an analog output of up to 10V, this module integrates into generator and switchboard control architectures where reliable automatic or semi-automatic breaker management is required.
Key Features
✓ Performs synchronisation and automatic circuit breaker closing for generator paralleling in marine power control systems.
✓ Supply voltage of 110VDC; measurement voltage 110V at less than 0.5mA; relay output rated at maximum 250VAC or 24VDC at 8A; analog output up to 10V — as specified on the original nameplate.
✓ UL-rated for use at maximum 450VAC (measurement) and limited to 24VDC and 110VAC supply under UL compliance conditions, subject to confirmation of applicable installation requirements.
✓ Designed for integration into DEIF generator control panels and compatible marine power management architectures; compatibility with specific panels or controllers should be confirmed against system drawings and configuration details.
✓ Suitable for installation in protected switchboard or control panel environments onboard; replacement of this module should follow manufacturer procedures and be carried out by qualified marine electrical engineers to maintain system integrity.
Marine Applications
✓ Generator paralleling and load sharing control systems on merchant vessels, offshore platforms, and naval auxiliaries.
✓ Automatic and semi-automatic switchboard management systems requiring precise breaker closing synchronisation.
✓ Integrated power management systems on cruise ships, ferries, and large yachts with multiple generator sets.
✓ Emergency and harbour generator changeover systems where safe synchronisation is a critical operational requirement.
✓ Retrofit and upgrade projects on existing DEIF-based power control systems requiring module replacement or system modernisation.
Why Marine Engineers Choose
The DEIF HAS-111DG is valued for its dedicated synchronisation function, robust relay output ratings, and compatibility with established DEIF marine power control architectures — making it a reliable choice for maintaining safe generator paralleling operations across a wide range of vessel types and power system configurations.
Ideal For
Merchant cargo vessels, offshore support vessels, ferries, cruise ships, platform supply vessels, and any commercial or industrial marine application utilising DEIF-based generator control and power management systems.
