PULS UC10.241 and UC10.242 DC buffer modules

The PULS UC10.241 and UC10.242 DC buffer modules 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.

One of the key features of the modules is a greater than 10 years operational lifetime expectancy and, unlike 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 and are capable of providing full output power between -40 and +60°C and with quick-release spring clamp terminals it makes wiring quick and easy.

Other features include a digital inhibit input that when activated turns off the output and buffering and provides unit status back to a control system using a relay output.
