New PULS 40A DC UPS controller now available
A new DIN-rail mounted controller for uninterruptible power supplies has been announced by PULS
PULS Power has announced the arrival of its new UB40.241 40A rated DIN-Rail mounted controller for uninterruptible power supply systems. The new model is now the most powerful UPS controller in the PULS range, which already includes models providing up to 20A capacity. In combination with a 24Vdc power supply and an external battery pack, the company says that it enables the reliable bridging of power failures and voltage fluctuations, thus preventing system damage, costly downtime, time-consuming restarts, and the loss of critical data.
Applications targeted with the new controller include Industry 4.0, security and CCTV, instrumentation and measuring systems. While the system power supply provides sufficient voltage, the DC-UPS controller will charge 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.
PULS claims that a unique feature of the UB series is its PULS 1-Battery concept. To ensure the longest possible battery life, each 12V battery is charged and monitored separately, a smart function which eliminates the need to match batteries. The UB40.241 allows precise charging, testing and usage of the battery capacity.
The control unit can be combined with different battery sizes from 12Ah to 200Ah with a selector on the front of the device making it easy to adjust it to the corresponding battery size. Power output is decoupled from the input to provide separate circuits for buffered and non-buffered loads.
To ensure safe and reliable operation, the UB40.241 has various battery diagnostic functions including an early pre-warning signal when the battery is low. Battery charging is temperature-controlled which is stated to have a positive effect on 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 reasons, an inhibit-input signal is included to enable phases without enforced buffering.
The PULS UB40.241 has an operating temperature range from -25°Celsius to +70°Celsius, 50% extra output power for up to 5s, and also has fully international safety agency approvals and a 3-year warranty.
