The DEIF CSQ-3 is a marine-rated multi-function synchroscope meter designed for accurate generator synchronisation monitoring within shipboard power management and marine control systems. As a critical component in generator paralleling operations, it measures and displays the phase angle relationship between an incoming generator and the live busbar, enabling safe and precise synchronisation before breaker closure. Its role in preventing out-of-phase connections makes it an operationally essential instrument in any vessel’s electrical power distribution architecture.
Key Features
✓ Dual-input synchroscope functionality monitoring busbar input at 450V / 0.5mA and generator input at 450V / <20mA, compatible with 50/60Hz systems.
✓ Sync output rated at 250VAC / 24VDC at 8A resistive, supporting both AC and DC control circuit integration depending on panel configuration.
✓ Designed for marine environments and compatible with DEIF power management and generator control panel architectures typical in shipboard installations.
✓ Panel-mount instrument suitable for installation within main switchboards, generator control panels, or power management system enclosures — subject to confirmation of physical fitment and local wiring arrangement.
✓ Replacement of this unit should be carried out by a qualified marine electrician; compatibility with existing wiring, transformer ratings, and control logic should be verified prior to installation.
Marine Applications
✓ Generator synchronisation panels aboard merchant vessels, tankers, bulk carriers, and container ships requiring parallel operation of multiple generating sets.
✓ Offshore support vessels and platform supply vessels where reliable power management and generator load sharing are operationally critical.
✓ Passenger vessels and RoPax ferries with complex busbar configurations requiring continuous synchronisation monitoring across multiple generator sets.
✓ Naval auxiliaries and government vessels operating power plants with strict requirements for safe generator paralleling procedures.
✓ Retrofit and upgrade projects on existing switchboard panels where an original DEIF synchroscope meter requires like-for-like replacement.
Why Marine Engineers Choose
The DEIF CSQ-3 is a trusted instrument within DEIF’s established marine power management ecosystem, offering reliable synchronisation indication with clearly defined input and output ratings. Its compatibility with standard 450V shipboard systems and dual-voltage sync output makes it a practical and dependable choice for generator paralleling applications across a wide range of vessel classes.
Ideal For
Merchant vessels, offshore support vessels, tankers, bulk carriers, container ships, passenger ferries, and any commercial or industrial vessel operating multi-generator power plants requiring synchronisation monitoring as part of the marine control system.
Technical Support & Compliance
Remote technical guidance, onboard commissioning support, testing assistance, and integration advice are available to help ensure correct installation and operation of the DEIF CSQ-3 within your vessel’s power management system — subject to confirmation of your specific configuration. For retrofit or upgrade projects, compatibility should be verified against the existing panel design, transformer ratings, and control wiring. To confirm suitability, buyers are encouraged to share nameplate photographs, the original part number (2034120068 C / 100037986-00064), panel drawings or schematics, the system model and software version where applicable, and the vessel name or IMO number. All compatibility assessments are subject to confirmation based on the information provided.
