Helios Power Solutions No-Break ™ DC UPS technology represents a truly unique, comprehensive approach to providing uninterruptible and secure DC power when you need it.

No-Break ™ DC UPS systems maximise the integrity of standby battery installations, whilst optimising the life and availability of back up batteries.  They are now available with Serial and Ethernet Communications options.

 The No-Break ™ system is the ideal solution for:

  • Critical systems of 100W to 750W (and above using parallel operation)
  • Applications requiring continuous on-line monitoring of battery and charger status
  • Providing cost-effective management of your battery system investment

Other features include:

  • Ability to view power supply data remotely
  • Automatic or manually initiated battery condition testing to ensure availability of standby power
  • The battery condition test feature of the No-Break ™ DC system determines the condition of the back-up batteries and will provide an early warning of potential failure. This gives plant operators enough warning to replace the faulty batteries before they are required, like in the event of a mains power failure. Battery condition tests are mandatory on some fire alarm systems and are now commonly specified by consultants for critical industrial systems.
