Installation and Setup Overview

Installing the DECS100-B05 automatic voltage regulator requires qualified electrical technicians familiar with generator control systems. General Power recommends professional installation to ensure optimal performance and safety:

Pre-Installation Requirements: Before installing the DECS100-B05, verify generator specifications match the AVR's voltage sensing range and current output capacity. Ensure proper current transformers (5A secondary) are installed for VAR/PF control functionality. Review the complete Basler Electric installation manual and verify all mounting hardware and connection terminals are available.

Mounting: The DECS100-B05 features a compact design suitable for panel mounting or DIN rail installation within the generator control enclosure. Mount the unit in a location with adequate ventilation, protected from direct exposure to extreme heat, moisture, and vibration. Maintain recommended clearances for heat dissipation and service access.

Electrical Connections: Connect sensing inputs to the generator's voltage sensing transformers or directly to the alternator terminals based on your configuration (single-phase or three-phase). Wire the field output terminals to the alternator's exciter field winding, observing proper polarity. Connect current transformer secondaries to the designated CT input terminals for power factor and VAR sensing. Install all connections using appropriately sized conductors per electrical codes and manufacturer specifications.

Initial Configuration: After physical installation, configure the DECS100-B05 parameters including voltage setpoint, droop settings (if used), stability adjustments, and VAR/PF control parameters. These adjustments are typically made using potentiometers or digital programming interface depending on the specific configuration. Conduct initial startup under no-load conditions and gradually apply load while monitoring voltage regulation performance.

Testing and Commissioning: Perform comprehensive testing including voltage accuracy verification, response time measurement, and power factor control validation. Test protective functions including overvoltage, under-frequency, and CT loss detection. Document all settings and test results for future reference and troubleshooting.

Frequently Asked Questions About the BASLER DECS100-B05

Q1: What is the primary difference between the DECS100-B05 and other DECS-100 variants?
A: The DECS100-B05 variant specifically includes VAR/PF (reactive power/power factor) controlling capability with a 5A CT secondary configuration, but does NOT include voltage matching functionality. This makes the B05 ideal for single-generator applications or systems where reactive power management is required but parallel voltage matching is not needed. Other DECS-100 variants may include different combinations of voltage matching, different CT ratings, or alternative control features. Always verify the specific variant designation matches your application requirements.

Q2: Can the DECS100-B05 be used to replace my existing analog voltage regulator?
A: In most cases, yes. The DECS100-B05 can replace many older analog AVR systems on compatible generators up to 5MW capacity. However, successful replacement requires verification of several factors: excitation system compatibility, voltage sensing configuration, field current requirements, and whether VAR/PF control is desired in your application. The mounting dimensions and terminal configurations may differ from your existing regulator, potentially requiring minor modifications. General Power's technical team can help assess compatibility for your specific generator model.

Q3: What does VAR/PF control mean and do I need it for my generator?
A: VAR/PF control manages reactive power (VARs - Volt-Ampere Reactive) and power factor in your generator system. This functionality is essential for generators operating in parallel with other generators or the utility grid, as it enables the unit to share reactive loads appropriately and maintain desired power factor. If your generator operates as a single unit in island mode powering mostly resistive loads, VAR/PF control provides less benefit. However, for facilities with significant inductive loads (motors, transformers) or grid-connected applications, the B05's VAR/PF control optimizes system efficiency and stability.

Q4: What size current transformers do I need for the DECS100-B05?
A: The B05 variant is specifically designed for 5A secondary current transformers (5A CT). Your current transformers should be sized based on your generator's full load current on the primary side, with a 5:5 ratio or X:5 ratio (such as 100:5, 200:5, 500:5, etc.) depending on your generator's output current. The CTs must be installed in the generator output circuit to measure load current for power factor calculation and VAR control. Never operate the regulator with CT secondaries open-circuited, as this can cause dangerously high voltages and damage.

Q5: Is technical support available if I have installation or programming questions?
A: Absolutely. General Power provides technical support for all Basler Electric products we sell, including the DECS100-B05. Our team can assist with application questions, installation guidance, parameter configuration, and troubleshooting. Additionally, as an authorized dealer, we have direct access to Basler Electric's engineering support resources for complex technical issues. We recommend having your generator nameplate information, electrical diagrams, and specific questions ready when contacting our technical support team for most efficient assistance.
