Description
Updated SE350 revision.
Did you know
- Marathon Electric, a company with a history of producing electrical products since 1913, manufactures the SE350A. The SE350A is an encapsulated electronic voltage regulator designed for brushless AC generators.
- The SE350A is part of Marathon Electric's range of Automatic Voltage Regulators (AVRs), which also includes models like the DVR2000E and PM300. While the SE350A is a compact, encapsulated electronic AVR, the DVR2000E is a more advanced, fully digital voltage regulator.
- The SE350A is chosen for its ability to provide reliable and high-quality output voltage by automatically compensating for fluctuations in power factor, temperature, engine speed, and load. It is also valued for its compact, encapsulated design, which offers protection against moisture and contamination.
| Model | Sensing & Power Input | Continuous Output Power | Voltage Regulation | Operating Temperature |
|---|---|---|---|---|
| SE350A | 190-240 Vac | 73 Vdc at 3.5 Adc (255W) | ± 1.0% | -40°C to +60°C |
| DVR2000E | 95-132V AC or 190-264V AC | Max 63 VDC @ 8A (continuous) | ± 0.5% | -40°C to +70°C |
