The DEIF CSQ-3 Land is a multi-function synchroscope meter designed to monitor and display synchronisation parameters between a generator and a busbar during paralleling operations. As a core component within a Marine Control System, it provides operators with real-time visibility of phase angle, frequency difference, and voltage relationship — critical data needed to safely close a generator onto a live busbar. Reliable synchronisation is fundamental to vessel power management, preventing electrical faults and protecting both generating sets and distribution equipment during load transfer or parallel running.
Key Features
✓ Multi-function synchroscope functionality combining phase angle display and synchronisation status indication in a single panel-mounted instrument.
✓ Busbar input rated at 115V, 0.5mA, 50/60Hz and generator input rated at 115V, less than 20mA, 50/60Hz, with a sync output of 250VAC / 24VDC at 8A resistive as specified.
✓ Compatible with DEIF power management and generator control architectures; intended for integration within land-type panel configurations — specific system compatibility subject to confirmation against installation drawings.
✓ Designed for panel mounting in switchboard or generator control enclosures; installation environment and mounting cutout dimensions should be confirmed against DEIF documentation prior to fitting.
✓ Suitable for replacement or retrofit within existing DEIF-equipped control systems; compatibility with the target control panel or generator management unit should be verified using nameplate data and system drawings.
Marine Applications
✓ Generator synchronisation panels aboard merchant vessels, offshore platforms, and vessels operating multiple generating sets in parallel.
✓ Main switchboard and emergency switchboard installations where generator paralleling and load sharing are performed manually or semi-automatically.
✓ Power management system upgrades and control panel refits requiring direct replacement of existing synchroscope instrumentation.
✓ Vessels operating in dynamic positioning, anchor handling, or other high-power-demand modes where precise generator synchronisation is operationally critical.
✓ Shipyard commissioning, sea trials, and periodic maintenance programmes requiring the testing or replacement of synchronisation metering within integrated power control systems.
Why Marine Engineers Choose
The DEIF CSQ-3 Land multi-function synchroscope meter offers a purpose-built solution for generator paralleling applications, combining established DEIF engineering with clearly defined electrical ratings — making it a dependable choice for engineers maintaining or upgrading vessel power management and control systems.
Ideal For
Merchant vessels, offshore support vessels, platform supply vessels, anchor handling tugs, ferry operators, and any commercial or industrial marine application where DEIF-based generator control and synchronisation equipment is installed.
Technical Support & Compliance
Remote technical guidance, onboard commissioning support, integration assistance, and retrofit or upgrade consultation are available subject to confirmation. For applications requiring system testing or panel integration, buyers are advised to share nameplate photographs, part numbers, relevant wiring diagrams or system drawings, the existing panel or power management system model and software version, and vessel name or IMO number where applicable. Compatibility with specific DEIF control systems or third-party panels is subject to confirmation based on the information provided.
