Emirel V1-11 is a compact single-phase voltage relay designed for monitoring overvoltage and undervoltage conditions in AC mains. Adjustable thresholds (±20 %) and dual independent timers for VM and Vm ensure flexible protection against both short-term surges and dips. The device is self-powered and provides a clear LED indication of supply and alarm status.
Features
- Precise single-phase voltage supervision with adjustable VM and Vm limits
- Independent delay timers TM and Tm (0.5 to 30 s) for separate response tuning
- LED indicators: Green (ON), Red AM (overvoltage), Red Am (undervoltage)
- Form C relay output rated 5 A @ 230 VAC, high electrical endurance
- DIN panel mounting, 48 x 96 x 90 mm ABS case, IP54 front protection
