LPRC/2
- Under and Over voltage monitoring (Window)
- Selectable nominals for popular 3-wire or 4-wire supply voltages
- Detects incorrect phase sequence, phase loss and neutral loss (4-wire mode)
- Adjustable Trip levels and Time delay
- 2 x SPDT Relay outputs
- 17.5mm wide, DIN Rail mount
The product monitors it’s own three-phase supply and can be set for either 3-wire or 4-wire monitoring. There are two independent relays provided with one assigned to under voltage monitoring and other to over voltage monitoring. In addition to the measured voltages, all phases (and neutral if applicable) must be present and phase sequence correct for the relays to energise. If any of these conditions are not met, the relay(s) will de-energise.
