PULS UC10.241 and UC10.242 DC buffer modules

DIN rail-mount power supplier PULS has released the UC10.241 and UC10.242 DC buffer modules. They extend the buffer times currently offered by the UF20.241 and UF20.481 by utilising electrochemical double layer capacitors (EDLC), which can provide a backup time of up to 33 s for a 10 A load.

Unlike with DC UPS systems which utilise batteries, no cabinet ventilation is required. With a short charging time compared to that of batteries, the units are rapidly back in ready mode following a discharge. They also maintain a regulated output voltage in buffer mode of 22.5 V and are capable of providing full output power between -40 and +60°C. With quick-release spring clamp terminals, wiring is quick and easy.

Other features include an inhibit digital input which, when activated, turns off the output and buffering; and ready relay outputs to provide unit status back to a control system. The modules have an operational lifetime expectancy of 10+ years.
