Description
DEIF
RELAY
SYNCHROSCOPE
MODEL: CSQ-2
MARINE
VOLTAGE: 415V
The DEIF CSQ-2 is a marine-rated synchroscope relay designed for generator synchronising applications within shipboard power management and control systems. Operating at 415V, this instrument provides the visual or electronic indication required to confirm phase alignment between two alternating current sources before paralleling generators — a critical step in safe and stable vessel power distribution. As a core component of the marine control system, it supports switchboard operators and engineers in executing safe load transfers and generator changeovers.
Key Features
✓ Synchroscope relay function: provides continuous phase-angle comparison between incoming and running generator supplies to enable safe paralleling at 415V.
✓ Rated operating voltage of 415V as stated in original product data; further electrical parameters such as frequency range and burden are subject to confirmation from nameplate or documentation.
✓ Designed for integration within marine switchboard panels, generator control units, and power management systems typical of commercial and offshore vessel installations.
✓ Intended for switchboard or control panel mounting in the engine control room or main switchboard space; exact enclosure rating and mounting dimensions should be confirmed against vessel drawings.
✓ Replacement of the CSQ-2 restores critical synchronising functionality to the power control system; compatibility with existing wiring and panel cutouts should be verified prior to installation.
Marine Applications
✓ Main switchboard generator synchronising on cargo vessels, tankers, and bulk carriers where multiple alternators must be paralleled safely.
✓ Offshore support vessels and platform supply vessels requiring reliable power management during dynamic positioning operations and load transitions.
✓ Passenger ferries and ro-ro vessels where rapid, accurate generator changeover is essential to maintain uninterrupted hotel and propulsion power.
✓ Drill ships and semi-submersible rigs operating complex power distribution systems with multiple generator sets running in parallel.
✓ Naval auxiliaries and government vessels fitted with DEIF-based control and monitoring infrastructure requiring OEM-matched components.
Why Marine Engineers Choose
DEIF instrumentation is widely specified across commercial and offshore fleets for its reliability in demanding shipboard electrical environments. The CSQ-2 synchroscope relay is a direct-fit solution for vessels already equipped with DEIF power control panels, minimising integration risk and commissioning time when restoring switchboard functionality.
Ideal For
Cargo vessels, tankers, bulk carriers, offshore support vessels, platform supply vessels, passenger ferries, drill ships, and any commercial or government vessel operating DEIF-based marine power management and generator control systems.
Technical Support & Compliance
Technical assistance is available to support troubleshooting, onboard diagnostics, testing and commissioning, and integration of this synchroscope relay within existing switchboard configurations. Retrofit and upgrade guidance can be provided subject to confirmation of system compatibility. To confirm suitability for your installation, buyers are encouraged to share nameplate photographs, existing part numbers or wiring diagrams, the switchboard or control panel model and software version where applicable, and vessel name or IMO number. All compatibility assessments are subject to confirmation based on the information provided.
