Description: The Low Voltage Detector is a product intended to detect the absence/presence of voltage in electrical
networks up to phase-phase 380 V. It uses a system to read the voltage in the network, which detects the
absence/presence of voltage per phase sending a spontaneous event to the Distributor.
The equipment is flexible to adopt the communication module most adequate to the topology of the
Distributor, initially being offered with Modem Cellular or Sigfox. The design concept is based on low energy
consumption and low cost. Its power system uses the low voltage network itself associated with
ultra-capacitors, which keeps it maintenance-free and autonomy for up to 40 minutes without the presence
of a low voltage network.
Three-phase voltage detection of up to 380V by isolated opto-couplers.
AC main power supply from 90V to 240V.
Auxiliary source of ultra-capacitors with autonomy of 40 minutes.
IP65 Protection Degree.
Operating temperature range: -30 to 85°C.
Storage of up to 200 messages.
Message update every 60 minutes
Communication via Sigfox network or cellular modem with penta-band technology.
Capacity for 2 SIM cards
Data sent to a local server that converts the message into DNP3 protocol and forwards to SCADA.
