Voltage fluctuations and drops are a common problem in complex power supply systems. They can also cause some serious failures which mean production processes are interrupted, machines stop working and systems have to be reconfigured. Murrelektronik's buffer modules provide stability in power supply systems. The modules buffer the power that is supplied to the system to prevent voltage fluctuations that may cause a breakdown. They ensure that machines and systems continue to operate smoothly. The supplier has enhanced the MB Cap Ultra series with a new, more efficient buffer module. The new component, called MB Cap Ultra 40/24 3.6s, buffers a load current of 40A at a nominal current of 24V DC for a time of 3.6 seconds. The module is equipped with ultra capacitors that are maintenance-free for life.
