Phoenix QUINT-PS/1AC/12DC/20 Primary-Switched Power Supply With SFB
QUINT POWER power supply units – highest system availability due to SFB technology.
Compact power supply units of the new QUINT POWER generation maximize the availability of your system. Even the standard power circuit-breakers can be tripped reliably and quickly with the SFB technology (Selective Fuse-breaking Technology) and six times the nominal current for 12 ms. Defective current paths are disconnected selectively, the defect is limited and the important system parts remain in operation. A comprehensive diagnostics is carried out by continuously monitoring the output voltage and current. This preventive function monitoring visualizes the critical operating modes and reports them to the control unit before an error occurs.
• Quick tripping of standard power circuit breakers with dynamic SFB technology power reserve
• Reliable starting of difficult loads with static POWER BOOST power reserve
• Preventive function monitoring
• Can be used worldwide
• High degree of operational safety due to high MTBF > 500 000 h, long mains buffering times > 20 ms, high dielectric strength up to 300 V AC
