Important notice - We will be performing system maintenance from 4pm Friday 19th April. Whilst we are performing this maintenance there will be no pricing available or ability to place orders. This will last for 2-3 days. Please contact customer support for any enquiries 0116 284 9900. We apologise for any inconvenience caused.

The buffer module is connected in parallel with the power supply unit's 24 V dc output and is changed with a capacitor bank. If the primary voltage of the power supply unit falls to zero and the output voltage falls to 22.5 V dc, the buffer module is automatically switched in and overcomes the power failure. The buffer module can supply 20 A/24 V dc for 200 ms; if the load current is lower, the time increases. When connecting two modules in parallel, the time is doubled up to 20 A, alternatively, up to 40 A power supply can be connected for 200 ms. There are two status inputs that indicate when the buffer module is ready to discharge and when it is active. Additionally, there is an input for disconnection of the module for safety circuits and service, for example. A LED on the front shows the status. The buffer module requires no maintenance in that it lacks a battery and fits all applications for which one wants to avoid stops due to temporary power failures. Available for both the Dimension and Silverline series.
V -1 V must be used if working with voltages higher than 24 V dc, such as for compensation of voltage drops in cables. The module will then be activated when the voltage falls -1 V beneath the set voltage, faster than 0.54 V/s. (If the fall time is slower than 0.54 V/s, the buffer module is connected when the voltage reaches 22.5 V dc.)

Renowned for high-quality cable cutting and crimping tools, Klauke serves electrical contractors, cable jointers, and linemen across a spectrum of sectors
At OEM Automatic, we can supply a series of components for your one project. All under one roof. This case study discusses how we supplied several components for our customer's new electro-pneumatic control box.
To promote constant and reliable performance, as well as a longer life of parts in the vehicle, it is important to consider the right cable protector.
We have now added switch disconnectors to our range! Switch disconnectors contribute to the overall functionality and safety of electrical systems.
LOCC-Box from Lutze is an intelligent current monitoring device that provides reliable protection of DC circuits in a slimline 8.1mm housing.
OEM Automatic has integrated push-in technology into it's product offering for many years now. In this blog post, we'll explore the various benefits of push-in technology and some of the products we offer that make use of this innovation, such as push-in terminals, push-in sockets, and even push-in heaters.
