This buffer unit from PULS has been manufactured to a high standard, with a compact design that is ideal for use in panel board installations or other building-in applications where a suitable mechanical enclosure shall be provided to fulfil local requirements.
The unit stores energy in integrated electrolytic capacitors on occasions when the power supply provides sufficient voltages. In case of a mains voltage fault, this energy is released again in a regulated process. These mains faults are completely bridged by the buffer unit, increasing the reliability of the system as a whole.
Once mains power fails or is switched off, the buffer unit will continue to provide the load current for a defined period of time. Process data can be saved and processes can be terminated before the DC power switches off. Controlled restarts are subsequently possible.
