The KU-1948-SPU/D DC-to-DC converter and emergency power module, part of KDT's Cuprium passive range, is an exceptionally smart and safe solution for supplying power and uninterruptible backup (UPS) to video surveillance systems, switches and industrial racks.
Overview
The KU-1948-SPU/D DC-to-DC converter and emergency power module, part of KDT's Cuprium passive range, is an exceptionally smart and safe solution for supplying power and uninterruptible backup (UPS) to video surveillance systems, switches and industrial racks. When mains power fails, it switches to the battery circuit instantly and without interruption, delivering regulated output voltages and keeping sensitive equipment from shutting down. Intelligent thermal management, separate terminal blocks and an all-metal design that mounts easily on industrial DIN rails ensure fully stable, safe and reliable operation in network infrastructure.

Frequently asked questions: Infrastructure
Answers to common questions about this product line, from the KDT Help Center.
Where should I start when choosing the right infrastructure equipment?
Start by defining the intended use, the number of devices, the installation environment, the capacity required and your plans for future expansion. Then choose the model and technical specifications based on what the project actually needs.
Which technical specifications matter most for infrastructure equipment?
Depending on the project, the most important specifications are capacity, speed, compatibility, environmental ratings, management features and scalability. Basing your choice on a single figure is usually not enough.
Is a cheaper infrastructure equipment model always the right choice?
No. The purchase price is only one factor. You also need to consider reliability, features, service life, after-sales service and maintenance costs.
How do I work out how much capacity network infrastructure needs?
Base the calculation on the number of devices, actual usage, how long the system will be in use and how much the project is likely to grow. It is also wise to keep some capacity in reserve.
Can infrastructure equipment be upgraded later?
In many cases, some of the capacity or equipment can be upgraded. However, this depends on the product's architecture and its hardware limitations, so check before you buy.
