The buffer module is connected via 24 V dc unit. The capacitor bank consists of so-called supercapacitors EDLC (Electrochemical Double Layer Capacitors), which has a very large storage capacity compared with the electrolyte. Pulse novel buffer module is an active circuit which ensures that the capacitors will not be charged with high voltage which gives a very long life.
It requires no maintenance as compared to a DC UPS where the batteries must be replaced at regular intervals. The temperature range of -40 to +60°C with the longevity do Buffer modules are suitable in a variety of applications, especially suitable where service and maintenance is costly. If 24 V dc voltage is lost or temporarily falls below 22.5 V dc buffer connected device automatically and bridge the shortfall without any temporary dips. Data can be saved and machines can be shut down in a safe and controlled manner. As soon as the 24 V dc power is restored starting capacitors to charge. The tension is constant 22.25 V dc during the entire buffer period, the voltage drops are not at the end of discharge, thus ensuring that the connected loads do not fall off.
Relay outputs provide signals on the following status:
Ready: The relay closes when the capacitors are fully charged, the input voltage is 24 V dc level.
Buffering: The relay closes when the capacitors are discharged, voltage interruption.
In addition there is an input, Inhibit enabling shutdown of the buffer function using a 24 V dc signal.
