The DEIF CSQ-3 is a marine-grade multi-function synchroscope meter engineered to monitor and display synchronisation parameters between a generator and a busbar within a vessel’s power management and marine control system. By providing real-time visual indication of phase angle, frequency difference, and voltage matching, it enables operators and engineers to perform safe, accurate manual or assisted generator paralleling. Reliable synchronisation is fundamental to shipboard electrical safety, and instruments of this class are a core component of engine room control panels and switchboard assemblies on vessels of all types.
Key Features
✓ Accepts a 115V busbar input at 0.5mA and a 115V generator input at less than 20mA, supporting both 50Hz and 60Hz systems for broad shipboard compatibility.
✓ Sync output rated at 250V AC or 24V DC at 8A resistive, with a maximum of 40V DC at 10mA, enabling direct interface with synchronising relay and control circuits.
✓ Designed as a multi-function synchroscope, combining phase angle indication and frequency comparison in a single panel-mounted instrument, reducing wiring complexity on switchboards.
✓ Marine-rated construction suitable for installation in engine room control consoles, main switchboard panels, and generator control enclosures; specific ingress protection and approval details subject to confirmation from nameplate or documentation.
✓ Manufactured by DEIF, a recognised supplier to the marine and offshore industry, supporting compatibility with a range of DEIF power management and generator control systems — specific system compatibility should be confirmed prior to installation.
Marine Applications
✓ Main switchboard synchronising stations on merchant vessels, tankers, bulk carriers, and container ships requiring manual or semi-automatic generator paralleling.
✓ Generator control panels aboard offshore support vessels, platform supply vessels, and anchor handling tugs where reliable power distribution is operationally critical.
✓ Engine room automation and power management systems on cruise ships, ferries, and RoPax vessels managing multiple generator sets in parallel operation.
✓ Retrofit and upgrade projects on existing switchboards where ageing synchroscope instrumentation requires replacement with a compatible, marine-rated unit.
✓ Commissioning and testing of new generator installations on yachts, workboats, dredgers, and specialist vessels where accurate synchronisation indication is required during sea trials.
Why Marine Engineers Choose
The DEIF CSQ-3 is valued for combining multiple synchronisation monitoring functions into a single robust panel instrument, reducing installation footprint while delivering the accurate, reliable readout that safe generator paralleling demands in a marine environment.
Ideal For
Merchant vessels, offshore support craft, ferries, cruise ships, workboats, yachts, and any vessel class operating multiple generator sets that require precise synchronisation monitoring at the main or emergency switchboard.
Technical Support & Compliance
Specialist technical support is available to assist with identification, installation guidance, integration into existing power management or generator control systems, and commissioning of this synchroscope meter. Remote troubleshooting, onboard support coordination, and retrofit consultation can be arranged subject to confirmation. To verify compatibility and ensure correct supply, buyers are advised to share nameplate photographs, the full part number and revision code, panel or switchboard drawings, the generator control system model and software version where applicable, and vessel name or IMO number. All compatibility and suitability assessments are subject to confirmation based on documentation provided.
