DC UPS Systems

Altech delivers a complete range of DC power technologies designed to keep equipment running safely and reliably. The CBI DC-UPS Series combines a power supply, battery charger, backup module, and battery care system in one compact unit. It prioritizes the load during power interruptions, manages charging intelligently for lead-acid, gel, and Ni-Cd batteries, and prevents deep discharge while maintaining high efficiency.

For applications needing fast, maintenance-free backup, Altech’s C-Tec UltraCapacitor systems use advanced ultracapacitor technology to deliver rapid charge and discharge cycles. They are ideal where brief but frequent power losses occur, providing reliable support without battery wear or replacement cycles.

Altech also offers a full line of DIN-rail power supplies, built with wide input ranges, high efficiency, and comprehensive protections against short circuit, overload, and overvoltage. Designed for rugged industrial environments, these supplies meet UL and IEC standards, ensuring reliable operation across demanding applications.

Together, Altech’s DC-UPS devices, ultra-capacitor backup modules, and DIN-rail power supplies provide a complete ecosystem of industrial power continuity—covering everything from primary supply to smart energy storage and rapid backup.

CBI Series DC-UPS Solutions

CBI All In One UPS Power Solutions combine the requirements for several applications in just one device which can be used as power supply unit, battery charger, battery care module or backup module. The available power is automatically distributed among load and battery, while supplying power to the load always is the first priority. The maximum available current of the load output is two times the value of the device’s rated current.

If the device is disconnected from the main power source, the battery will supply the load until the battery voltage reaches 1.5 V per cell. This prevents the battery from deep discharge. CBI devices provide microprocessor controlled battery charging. Using algorithms, the battery’s condition will be detected and based on that, an appropriate charging mode is chosen. The real-time diagnostics system will continuously monitor the charging progress and indicate possibly occurring faults such as elements in short circuit, accidental reverse polarity connection or disconnection of the battery by the battery fault LED and a flashing code of the diagnosis LED.

CBI All In One UPS Power Solutions are suitable for open/sealed lead acid-, lead gel- and optionally Ni-Cd batteries. By using the battery-select-jumper, it is possible to set predefined charging curves for those battery types. The available charging options are recovery-, boost- and trickle charge. All CB devices are built in a rugged metal case with a DIN rail mounting bracket.

Ultra Capacitor DC-UPS

Ultra Capacitor based technologies provide an attractive yet efficient platform for both simple and complex applications.

The DC Back-Ups from Altech Corp.® utilize Ultra Capacitors as an innovative way to store energy within a compact design. In the event of a main power supply interruption, the energy stored in the Ultra Capacitors is released. The load is energized from the buffer module, until it‘s depleted.

Back up times depend on the state of the charge of the Ultra Capacitors and the load in which they are supplying. Compared with standard buffer modules, Ultra Capacitor units are capable of prolonged back-up times (up to 55 minutes) and fast discharges. Capacitors excel at controlled shutdown functions and allowing for the protection of computer systems. Backup times are dependent on the load and amount of Capacitors within the unit. Back up times can be calculated to better serve the requirements of required functions.

FEATURES

Works primarily in an online parallel configuration
Controlled shut down functions
Up to 40 A low discharge protection through load rejection
Ultra Capacitors have 15 years of life
Quick back up recharges due to the nature of Ultra Capacitors
DIN rail mount

REDUNDANCY BUFFER MODULE

PS-RDN20 is a 20A redundancy (decoupling) module for the 24V DC power system. Containing 2 sets of 20A Or-ing diodes with wonderful heat dissipation deployment, PS-RDN20 give you a new option for safe connection of 1+1 redundant set-up. Not only perfectly decouple power sources from each other as well as from the load, PS-RDN20 also provides users monitoring signals for both input channels through the built-in relays. Since there’s no switching components inside the module, PS-RDN20 will not arise additional EMI issues and should provide you a worry-free application platform!
