DC Helix

Network managed redundant DC power systems for uninterrupted power in mission critical applications.

FLEXPOWER HELIX are single voltage power systems specifically designed for mission critical applications that require redundant back up power for use in the Access Control or Security industry.

Two identical FPO power supplies are combined in a single enclosure with the Helix module to provide a single output voltage. In the event of a failure of the main power source, the Helix module will automatically switch the output to the backup FPO power supply.

HELIX is factory configured for 120 VAC operation and user configurable to 12 or 24 VDC output (factory default is 12 VDC), and available with single or multiple outputs. HELIX systems also feature comprehensive fault detection and reporting through local or network connection and come in a steel enclosure with lock and tamper switch.
