AVR R438 Automatic Voltage Regulator for Brushless Generators Genset Stabilizer High Stability & Efficiency

AVR R438 Automatic Voltage Regulator for Brushless Generators Genset Stabilizer High Stability & Efficiency Enhance your generator's performance with the AVR R438, a top-tier automatic voltage regulator designed specifically for brushless type generators. This essential accessory ensures your diesel genset operates with optimal stability and efficiency, providing reliable power output under various conditions. Compatible with a wide range of brushless generators. Ensures smooth and stable voltage output. Easy installation and maintenance. Durable construction for long-lasting reliability. Power input: 35-75VAC, (PMG, or auxiliary winding, single, three-phase) Inductive detection: 90-480VAC Maximum output: DC8A 75V Protection function: Built in low-speed, overexcitation, LAM function Adjustment rate: better than 0.5% Electrical protection function:When overloaded or short circuited, disconnect the voltage detection circuit and maintain the excitation current for 10 seconds, then restore it to approximately 1A send out The motor must be stopped (or the power switch must be cut off) in order to reset the protection function Gradient voltage recovery function:During the load input period, this function helps the unit to recover to its rated speed faster, thereby maintaining the voltage as follows Gradually increasing: If the speed drops to between 46-50Hz, the rated voltage will quickly recover with a slope; if When the speed drops below 46Hz, the prime mover requires more assistance, and the voltage will slowly recover to the reference value with a slope.
