CATERPILLAR 365-2076 VR6 AUTOMATIC VOLTAGE REGULATOR
CATERPILLAR 365-2076 is panel mounted marine VR6 series automatic voltage regulator AVR, designed for Caterpillar marine diesel generator excitation control system, widely fitted onboard cargo vessels, offshore platforms and heavy-lift ships for generator output voltage stabilization and excitation regulation. This marine AVR unit senses generator output voltage and automatically adjusts excitation current, maintaining stable output voltage under varying load conditions for Cat parallel genset operation.

The marine voltage regulator integrates voltage sampling circuit, power thyristor control circuit, surge protection, watchdog monitoring and status LED indicators, supports voltage parameter trimming, fault memory storage and overvoltage / undervoltage interlock function for marine generator power system supervision. Its generator voltage regulation & hardware diagnostics function continuously monitors generator voltage sampling signal, internal circuit and excitation output state, detects voltage drift, component failure and excitation loss fault, transmits AVR fault alerts and generator operating status to vessel AMS alarm console. The generator voltage regulation & hardware diagnostics ensures stable parallel power operation for marine Caterpillar genset control system. It enables reliable marine 365-2076 automatic voltage regulator operation under heavy vessel vibration and salt mist marine environments.

This Caterpillar 365-2076 VR6 voltage regulator delivers stable marine generator excitation control performance installed inside vessel generator control cabinet. The generator voltage regulation & hardware diagnostics adopts marine-grade flame retardant PCB assembly with EMC shielding against electromagnetic interference and mechanical shock. Marine electrical technicians rely on marine 365-2076 AVR operation to test voltage adjustment range, inspect excitation output and verify parallel load sharing during routine maintenance. It adopts standard panel mounting design for straightforward spare replacement and minimal marine generator control system downtime. Internal circuit boards use conformal coating to protect electronic components against salt mist, condensation and temperature fluctuation. It works cooperatively with Caterpillar diesel generator, current transformers and ship integrated alarm monitoring system. It is widely used as generator excitation spare hardware for Caterpillar marine low voltage genset parallel power control system maintenance and retrofit projects.
