The DEIF CSQ-3 Marine Multi-Function Synchroscope Meter is a precision instrument used in marine power management and generator control systems. Its primary function is to display and monitor the synchronisation status between an incoming generator and a live busbar, providing operators with the critical phase angle, frequency, and voltage matching data required before paralleling generators safely. As part of a vessel’s marine control system, this meter plays an essential role in preventing out-of-phase connection events that can cause significant damage to alternators, switchboards, and distribution equipment. It is typically mounted on main switchboards or generator control panels aboard a wide range of commercial and working vessels.
Key Features
✓ Multi-function synchroscope functionality with busbar input rated at 450V, 0.5mA, 50/60 Hz and generator input rated at 450V, <20mA, 50/60 Hz, providing accurate live synchronisation indication.
✓ Sync output supports both 250V AC and 24V DC at 8A resistive, with a maximum auxiliary signal of 40V DC / 10mA, enabling integration with automatic synchronising relays or control circuits.
✓ Designed for compatibility with DEIF marine power management and generator control panel architectures, subject to confirmation against the specific panel model and system configuration.
✓ Suitable for installation in main switchboard enclosures and generator control desks in the engine control room or machinery spaces; exact environmental ratings and mounting dimensions should be confirmed from the unit nameplate or DEIF documentation.
✓ Manufactured by DEIF, a recognised specialist in marine power control instrumentation, with products commonly found aboard vessels operating under class society requirements; certification status for this specific unit is subject to confirmation.
Marine Applications
✓ Main switchboard synchronisation panels aboard cargo vessels, bulk carriers, and container ships where multiple generators operate in parallel.
✓ Generator control systems on offshore support vessels, platform supply vessels, and anchor handling tugs requiring precise power management.
✓ Engine control room instrumentation on passenger ferries and ro-ro vessels where reliable busbar monitoring is critical to operational continuity.
✓ Power distribution control panels on dredgers, crane vessels, and other special-purpose workboats with complex generator arrangements.
✓ Retrofit and upgrade projects on existing switchboard installations where the original DEIF synchroscope meter requires direct replacement to maintain system integrity.
Why Marine Engineers Choose
Marine engineers specify the DEIF CSQ-3 for its reliable multi-function display, its straightforward integration into DEIF-based power control systems, and the confidence that comes from sourcing OEM-matched instrumentation for critical synchronisation duties in demanding shipboard environments.
Ideal For
Cargo ships, bulk carriers, container vessels, offshore support vessels, platform supply vessels, ferries, ro-ro ships, dredgers, crane barges, and any commercial or working vessel operating multi-generator power plants with main switchboard synchronisation requirements.
Technical Support & Compliance
Remote troubleshooting guidance, onboard technical support, testing and commissioning assistance, repair evaluation, retrofit integration, and system compatibility confirmation are available subject to review of the specific installation. To confirm suitability and compatibility for your vessel’s power control system, buyers are encouraged to share nameplate photographs, available part numbers or drawing references, the switchboard or generator control panel model and system version, vessel name, IMO number, and the full scope of the replacement or upgrade requirement. All compatibility and certification claims are subject to confirmation based on documentation provided.
