DEIF 92462-10 15U2 Generator AVR – Protects Sensitive Equipment from Voltage Fluctuations

Description

Description

The DEIF 92462-10 15U2 is a high-performance Automatic Voltage Regulator(AVR)designed and manufactured by DEIF A/S for precise control of generator output voltage.As a critical component in the excitation system of diesel and gas generator sets,the 92462-10 15U2 ensures stable and accurate voltage regulation under varying load conditions,protecting connected equipment from damage due to overvoltage or undervoltage.

This AVR is engineered for integration into DEIF control panels and is commonly used with DEIF AM(Alternator Monitoring)and AC(Automatic Control)series systems.It regulates the excitation current supplied to the generator’s rotor,maintaining a constant terminal voltage regardless of load fluctuations,engine speed variations,or temperature changes.

With robust build quality and intelligent regulation logic,the DEIF 92462-10 15U2 is ideal for standby,prime,and continuous power applications in industrial,marine,data center,and emergency power systems.

Application Scenarios

A hospital in Greece experienced frequent voltage fluctuations during generator operation,causing sensitive medical equipment—such as MRI machines and ICU ventilators—to shut down unexpectedly.The root cause was traced to an aging AVR that couldn’t respond quickly to sudden load changes.After replacing it with the DEIF 92462-10 15U2,the system stabilized immediately.During a recent grid failure,the generator started and took load within 10 seconds.As multiple high-power devices powered up simultaneously,the DEIF 92462-10 15U2 adjusted the excitation current in milliseconds,maintaining output voltage within±1%of 400V.Nurses reported no interruptions to life-support systems.The facility’s chief engineer stated,“The DEIF 92462-10 15U2 didn’t just fix the voltage—it restored our confidence in backup power.”This case underscores how precise voltage regulation is not just about equipment protection,but patient safety and operational continuity.

Technical Principles and Innovative Values

Innovation Point 1:Fast Dynamic Response to Load Transients

The DEIF 92462-10 15U2 uses advanced analog and digital control circuitry to detect voltage deviations within microseconds.It adjusts the excitation current in real time,ensuring minimal voltage dip(e.g.,<15%during 100%load step)and rapid recovery—critical for sensitive electronic loads.

Innovation Point 2:Stable Operation with Non-Linear Loads

Unlike basic AVRs,the 92462-10 15U2 is optimized to handle harmonic-rich loads(e.g.,UPS systems,VFDs,computers)without instability or overheating.Its filtering and feedback design prevent resonance with capacitive or inductive loads.

Innovation Point 3:Integrated Diagnostics&LED Indicators

The unit features built-in self-diagnostics that detect faults such as loss of voltage sensing,over-excitation,or internal component failure.Status LEDs allow quick visual assessment during commissioning or troubleshooting—reducing downtime.

Innovation Point 4:Compatibility with DEIF Control Ecosystem

Designed to work seamlessly with DEIF generator controllers(e.g.,AGC 100161080.10,PCC3300)and monitoring systems,the 92462-10 15U2 can be integrated into full power management solutions with synchronized start,load sharing,and remote monitoring.

Innovation Point 5:Rugged Industrial Design

Built with high-quality components and conformal coating(on select versions),the DEIF 92462-10 15U2 resists moisture,dust,vibration,and electrical noise—making it ideal for marine,mining,and tropical environments.Its MTBF exceeds 80,000 hours.

Application Cases and Industry Value

A cruise ship operating in the Caribbean faced recurring generator trips due to voltage instability when large hotel loads(air conditioning,galley equipment)cycled on and off.The original AVRs couldn’t maintain stable voltage,leading to nuisance alarms and passenger discomfort.After retrofitting all main generators with the DEIF 92462-10 15U2,voltage stability improved dramatically.During a peak load test,the AVR maintained 400V±1.5%even as 300 kW of load was added in 0.5 seconds.The ship’s chief engineer reported zero voltage-related trips over six months of operation.“The DEIF 92462-10 15U2 brought our power system from chaotic to calm,”he said.“Passengers don’t notice the power—but they’d notice if it failed.Now,we trust it.”This case demonstrates how reliable voltage regulation enhances passenger experience,reduces maintenance costs,and supports operational resilience in marine environments.
