The series of outdoor phase selectors SELBLUOUT301 of BLUNERY are a complete and fully integrated solution to increase redundancy for AC single phase loads (i.e.: UPS for HFC networks). It is a very convenient way to reduce the use of the UPS’ batteries if one phase shuts down.
The SELNVTPEF301 intelligent module included in this units, allows for the connection of single phase AC loads into three phases AC lines.
Protection devices, AC & DC distribution, status signaling, etc. are included in the unit for a quick and easy deployment in the field.
The instalation requires only two steps: the connection of the AC source to the input terminal block and the load to the output terminal block.
The powerfull firmware embeded in the SELNVTPEF301 intelligent modules allows monitoring all the AC source waveform parameters for each phase, connecting the best one to its output.
MAIN FEATURES
• Up to 3.5KW loads can be safely connected to its output.
• Outside status indicators for AC line, AC output and fail.
• Adjustable parameters such as: transfer to main phase, high and low line voltage, transfer delay, etc.
• High current DIN terminal blocks for a quick AC (line & load) wiring.
• By-pass switch for service and maintenance.
• Field replaceable SELNVTPEF301 intelligent module.
• Compatible with worlwide line standards: voltage and frequency.
