Technical Specifications
The BE2000E accepts input voltages from 100 to 240 VAC at 50 or 60 Hz. The sensing input range is 80 to 300 VAC. The regulator provides continuous output current of 5 A with a peak capability of 10 A. Voltage regulation is within ±0.5 percent. The transient response time is less than 20 milliseconds. Operating temperature range is -40 to +70 degrees Celsius, and storage temperature is -40 to +85 degrees Celsius. The unit is rated for 95 percent non-condensing humidity. Weight is approximately 2.5 kilograms.
Protection and Control Functions
Built-in protection includes overexcitation limiting, underfrequency roll-off, and V/Hz limiting. These functions protect both the generator and connected loads from abnormal operating conditions. The BE2000E also includes a sensing loss protection circuit that reduces excitation if the generator voltage sensing signal is lost, preventing overvoltage. The regulator can be configured for different droop settings to allow parallel operation with other generators.
Installation and Configuration
Installation requires mounting the unit on a control panel or inside a switchgear enclosure. Connections include power input, voltage sensing leads, and field output wiring. Jumpers and potentiometers are used to set the regulator to match the generator characteristics and application requirements. The soft start time, stability, and voltage setpoint are adjustable. Commissioning involves verifying correct rotation, setting the voltage, and checking dynamic response under load steps.
Applications
The BE2000E is widely used in diesel and gas generator sets, marine power systems, standby and prime power plants, and cogeneration facilities. Its robust design and flexible configuration make it suitable for industrial, commercial, and military applications where reliable voltage control is essential.
Environmental and Compliance
The BE2000E is built to withstand vibration, humidity, and temperature extremes commonly found in generator rooms and outdoor enclosures. It meets UL, cUL, and CE marking requirements and is RoHS compliant. The regulator also meets relevant EMI/EMC standards for industrial equipment, ensuring reliable operation in electrically noisy environments.
Conclusion
Basler Electric BE2000E offers a reliable, precise, and feature-rich solution for automatic voltage regulation of brushless generators. Its digital control, protection functions, and flexible power options make it a preferred choice for generator manufacturers and end users worldwide.
