Electrical Specifications

Power input
• Nominal input voltage 24VDC (9 to 36V) or 110VDC (77 to 150V) according to EN50155
• Two redundant inputs
• Power-on threshold: 0.7xUn = 16.8V (for 24VDC PSU) or 77V (for 110VDC PSU)
• Power change-over threshold (when a secondary power source is connected): 12V (for 24VDC PSU) or 66V (for 110VDC PSU) (lower input voltage results in automatic switch to secondary power source)
• Minimum input voltage when no secondary power source is connected: 9V (for 24VDC PSU) or 66V (for 110VDC PSU)
