PULS 24 VDC 15 A Buffer Units from Control Logic

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 using Electrochemical Double Layer Capacitors (EDLC) which can provide a back-up time of up to 33 s for a 10 A load.

Some of the key features of these modules are good operational lifetime expectancy and, unlike with DC UPS systems which use 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, are capable of providing full output power between -40 and +60°C and with quick-release spring clamp terminals, wiring is quick and easy.

Other features include an inhibit digital input that when activated turns off the output, buffering and ready relay outputs to provide unit status back to a control system.
