Description
1. Product Description
⚙️ The Basler Electric DECS-200-2L is a microprocessor-based digital excitation control system designed to regulate synchronous generator excitation. It supports automatic voltage regulation (AVR), field current regulation (FCR), reactive power (VAR), and power factor (PF) control modes.
🔧 The unit features a pulse-width-modulated (PWM) power stage, generator voltage and current sensing, excitation limiting, soft-start buildup, and monitoring functions. It supports excitation outputs of 32 V DC, 63 V DC, or 125 V DC, with continuous field current up to 15 A, depending on the application configuration.
