Descrição de R438 Automatic Voltage Regulator for Generator, Stable Power Output, Durable Replacement Part

I'm checking the source text shape and will keep the output to exactly five HTML paragraphs, preserving the technical details while removing brand terms and any promotional wording.

Soft-start voltage ramping is included for smoother operation, along with sensing voltage loss protection to help maintain stable performance. The unit supports 120 or 240 Vac sensing, with jumper-selectable configuration for flexible setup.

Under-frequency roll-off protection is built in, and an under-frequency LED indicator provides a clear status signal during operation. These functions help the regulator respond appropriately when operating conditions change.

Sensing and power input specifications are designed for practical use in compatible systems: voltage range is 40-150 Vac, three phase, with 50/60 Hz frequency selected by jumper. This allows the regulator to adapt to different installation requirements.

Output performance is specified at a maximum of 160 Vdc with 120 Vac input and a maximum current of 8 A. Voltage regulation is less than +/-0.5% with 4% engine governing, and less than +/-1% under standard conditions, supporting consistent electrical control.

The colour is black, and the material is plastic. Package contents include 1 automatic voltage regulator and 1 English manual.
