DECS100-B11 AVR Voltage Regulator for Diesel Genset Parts

Product Introduction: The DECS100-B11 AC Voltage Regulation Stabilizer AVR is a generator spare part for diesel genset excitation and voltage regulation service. It is typically used in industrial power generation, standby power systems, service workshops, rental fleets, and aftermarket repair channels where a voltage regulator board is required to help maintain stable generator output. The module is suitable for replacement selection where the existing AVR, terminal layout, sensing input, and generator excitation requirements match the installation. Based on the supplied product information, it supports 190-240 Vac sensing/power input at 50/60 Hz and provides DC excitation output for alternator field control. Functional features such as soft start voltage ramping, sensing voltage loss protection, jumper selectable sensing, under frequency roll off protection, and an under frequency LED indicator make it relevant for maintenance teams managing generator reliability and load response. The visible open PCB structure with heat sink, capacitors, wiring terminals, and control interfaces indicates a panel-mounted electronic AVR for genset electrical control cabinets. For B2B buyers, this product supports spare part stocking, repair service, project replacement, and OEM/ODM procurement programs by offering a practical sourcing option for generator maintenance and power backup equipment supply chains. Confirm compatibility with the generator model, wiring diagram, excitation system, and original part before ordering.
