Overview

The BASLER DECS100-A11 Automatic Voltage Regulator (AVR) represents advanced microprocessor-based digital voltage control technology designed for reliable generator operation across a wide range of applications. This precision-engineered AVR automatically maintains consistent voltage output from your generator, protecting sensitive electrical equipment and ensuring stable power delivery under varying load conditions. Suitable for generators up to 5MW, the DECS100-A11 delivers robust performance with 63Vdc and 7.0Adc continuous output capacity, making it an ideal replacement or upgrade component for industrial, commercial, and emergency backup power systems.

The A11 variant of the DECS-100 series is specifically configured without VAR/PF controlling capabilities but includes essential voltage matching functions and compatibility with 1A CT secondary current transformers. This AVR senses voltage across multiple configurations including 100/120, 200/240, 400/480, and 600Vac in both single-phase and three-phase applications, providing exceptional versatility for diverse generator installations. The digital control architecture ensures superior voltage regulation accuracy compared to traditional analog AVRs, with faster response times to load changes and enhanced protection features that extend generator lifespan and improve overall system reliability.

Key Specifications

Compatible Alternator Models

The BASLER DECS100-A11 AVR is engineered for broad compatibility with numerous generator and alternator configurations, making it a versatile solution for replacement or new installations. This voltage regulator is fully compatible with Basler-equipped generators from leading manufacturers including Marathon, Stamford, Leroy Somer, Mecc Alte, and Newage. It works seamlessly with brushless alternators featuring PMG (Permanent Magnet Generator) or shunt excitation systems up to 5MW capacity. The DECS-100 series has been extensively tested and approved for use with industrial gensets, marine power systems, co-generation applications, and renewable energy installations. Whether you're maintaining existing Basler-equipped generators or upgrading from older analog AVR systems, the DECS100-A11 provides reliable voltage regulation across single-bearing and double-bearing alternator designs. The unit's flexible sensing inputs accommodate various voltage configurations, while the 1A CT secondary rating ensures compatibility with standard current transformer installations commonly found in medium-sized generator applications. This AVR is particularly well-suited for applications requiring stable voltage output without the complexity of reactive power control, making it ideal for standalone generators, non-paralleling installations, and backup power systems where voltage matching is the primary requirement.

Installation Overview

Installing the BASLER DECS100-A11 Automatic Voltage Regulator requires attention to proper wiring connections and configuration settings to ensure optimal generator performance. Follow these general installation steps:

• Step 1 - Safety Preparation: Completely shut down the generator, disconnect battery power, and lock out all electrical sources. Verify zero voltage at all terminals using appropriate testing equipment. Remove the existing AVR carefully, documenting all wire connections with photographs or detailed labeling to ensure accurate replacement wiring.
• Step 2 - Mounting and Connections: Mount the DECS100-A11 securely using DIN rail or panel mounting hardware in a location with adequate ventilation and protection from moisture and vibration. Connect sensing inputs according to your generator's voltage configuration (single or three-phase), ensuring proper phase relationship. Connect the field output terminals to the alternator exciter field, observing correct polarity.
• Step 3 - Current Transformer and Configuration: Connect the 1A current transformer secondary wiring to the designated CT terminals on the AVR, maintaining proper phasing. Configure any necessary jumpers or DIP switches according to your specific generator voltage and frequency requirements as outlined in the Basler installation manual.
• Step 4 - Testing and Calibration: Restore power to the generator control system, start the generator under no-load conditions, and verify proper voltage buildup. Monitor voltage regulation performance under varying loads, and adjust voltage set-point trim controls if necessary to achieve desired output voltage. Confirm stable operation and proper voltage recovery following load steps before returning the generator to service.

Note: Complete installation instructions are provided with each AVR. For complex installations or parallel generator configurations, consult with a qualified generator technician or contact General Power technical support for guidance.

Frequently Asked Questions

Q: What does the BASLER DECS100-A11 AVR do?
A: The DECS100-A11 is an automatic voltage regulator that continuously monitors your generator's output voltage and automatically adjusts the excitation current to the alternator field windings to maintain consistent voltage output. This protects connected equipment from voltage fluctuations, ensures stable power delivery under changing load conditions, and prevents damage to sensitive electrical devices. The microprocessor-based digital control provides superior accuracy and faster response compared to older analog regulators.

Q: How do I know if my AVR is failing?
A: Common signs of AVR failure include erratic voltage output that fluctuates significantly under load, inability to build voltage when the generator starts, over-voltage or under-voltage conditions that persist despite adjustments, or complete loss of generator output voltage. You may also notice unusual surging, poor voltage recovery after load changes, or visible damage to the AVR such as burned components or loose connections. If you experience any of these symptoms, testing and likely replacement of the AVR is recommended.

Q: Is this an OEM Basler product?
A: Yes, absolutely. General Power supplies only genuine, factory-new OEM Basler Electric components.
