PULS introduces Ultracap Buffer Modules

PULS introduces Ultracap Buffer Modules. Back-up for minutes with a DC-UPS utilising only one 12V battery or for seconds with our battery-free buffer module with no battery wear out. This prevents down time, loss of data and long restart sequences.

Currently, the commonly used battery for DC-UPS systems is VRLA battery (Valve regulated lead acid battery) which has many shortcomings as below:

• Short lifetime
• Must be replaced periodically
• Limited temperature range (0…+40ÀöC), out of which may cause over-aging of batteries, the reduction of the battery’s capacity and even the generation of the flammable and explosive gas, Hydrogen
• The heavy metal lead which is contained in the battery production process and expiring process is difficult to be handled properly, resulting the environmental pollution and being harmful to people’s health

In contrast, the “gold capacitor” Ultracap EDLC (Electrochemical Double Layer Capacitors) with the following advantages can meet the requirements of new technologies and global environmental trends:

• Long lifetime expectancy
• Maintenance-free
• Wide temperature rage for the increasing demands of outdoor applications
• Higher power and longer buffer time with the extremely low resistance
• EDLC prices became lower during the last years and using them as an energy source is now affordable.

Therefore, PULS automation power supply releases the new UC10-Series EDLC Ultracap buffer modules in its DIMENSION product line which represents innovation and reliability.

Once again, PULS set a new standard for the industrial DC UPS field with the following features:

• Built-in Ultracaps (EDLCs) instead of lead batteries
• Active balancing of the capacitor string brings the longest lifetime and buffer time
• Wide ambient temperature range from -40ÀöC to +60ÀöC enable it to be applied in harsh environment
• One unit includes the controller of UPS and the Ultracap so that it can be installed in small cabinet
• More than 10 years’ typical operational lifetime, and in which the EDLCs are proven components for more than 15 years
• No generation of Hydrogen, no ventilated cabinets required
• Regulated output voltage in buffer mode (22.5V)
• 50% Power Boost (15A) continuously allowed
• Output is decoupled from the input to separate load circuits into buffered and non-buffered sections; Only the critical load will consume the reserved power from Ultracaps when the power is off
• Short charging time, unit turns rapidly back in ready mode.

PULS automation power supply’s new UC10-Series provide the UPS system with wider available temperature range, longer lifetime and more applications, such as railway industry, solar industry, wind power industry, energy storage technology industry, outdoor applications, hybrid automobile industry, as well as military and many other harsh environment applications. In addition, PULS also provides conformal-coated-version of UC10.241 to meet the specific requirements of applications in severe vibration or high humidity environment.
