More details

The Profitec S N1 is a 100 % analog charger. All regulation and monitoring PCBs (built up in SMD method) contain no software and no programmable components or devices. The invention of a 100 % free-of-software rectifier is due to the security of DC power supply and new requirements for safety and qualification processes.

OPTIONS

Overvoltage limiter (Forsmark-event)
In case of input voltage variation, independent of the input voltage gradient, the duration and its maximum value, the patented overvoltage limiter reduces the value of the DC output voltage to less than 115 % of the nominal DC voltage. Th overvoltage detection is a self-acknowledging fault.
Parallel mode (for output current extension or redundancy)
Diagnostic device for annual checks as required by NPPs
Forced cooling for ambient temperatures up to 50 °C without de-rating
Design as +/- system
Higher IP rating
Battery feeder cubicles, seismic-proofed
Battery symmetry monitoring
Battery charging circuit monitoring
