DIN-rail mounted controller from PULS Power bridges fluctuations
For uninterruptible power supply (UPS) systems, the UB40.241 is a 40A DIN-rail mounted controller from PULS Power.
It is the most powerful UPS controller in the company’s range, which includes a variety of models up to 20A capacity. In combination with a 24V DC power supply and an external battery pack, it enables the reliable bridging of power failures and voltage fluctuations, says PULS. This can prevent system damage, downtime, time-consuming restarts and the loss of critical data.
Applications include intelligent buildings and factories, industry 4.0, security and CCTV, instrumentation and measuring systems.
The system power supply provides sufficient voltage and the DC-UPS controller charges the battery bank. Should the supply voltage suddenly fail, the energy stored in the battery is released to the DC bus in a regulated process.
The PULS 1-Battery in the UB series, ensures the longest possible battery life, says PULS. Each 12V battery is charged and monitored separately and eliminates the need to match batteries. The UB40.241 allows precise charging, testing and optimised usage of the battery capacity.
The control unit can be combined with different battery sizes from 12 to 200Ah. A selector on the front of the device allows an adjustment to the corresponding battery size. Power output is decoupled from the input to provide separate circuits for buffered and non-buffered loads.
The UB40.241 has various battery diagnostic functions including an early pre-warning signal when the battery is low. This ensures safe and reliable operation of the entire system. Battery charging is temperature-controlled which also has a positive effect on the battery life. It also features a selectable buffer time limiter as well as signal contacts for system ‘ready’, ‘buffering’ and ‘replace battery’. For safety and maintenance, there is an inhibit-input signal to enable phases without enforced buffering.
The PULS UB40.241 has an operating temperature range from -25 to +70 degrees C, which is 50 per cent extra output power for up to five seconds, has fully international safety agency approvals and a three-year warranty.
