Phoenix power supplies provide the following features:
• Convection cooling – no cooling fans are used
• Ambient rating for enclosure design: -40 to 70°C (-40 to 158 °F) free convection (no fans).
• ±2% voltage regulation
• Compatible with required environmental and agency standards
• Normally Open dry contact and LEDs for status feedback. When the power supply is working correctly, the contact is
closed. When a problem is detected, the contact is open.
• Power supply outputs can be paralleled (Phoenix does not current share but supports redundant operation using an
external FET-OR redundancy module.)
• Current limit and over-voltage protection of outputs. The current limit is rectangular rather than being a fold-back limit.
The current limits at the defined value and output voltage is decreased.
• Input filtering for EMC compliance for incoming and out-going conducted EMI
• CE Mark for Low Voltage Directive (LVD) and EMC
• UL 508 listing
The following table provides a list of the Phoenix (QUINT) Contact power supplies and FET-OR redundancy modules (GE
Part Number Series 342A3648), including a summary of each supply’s features and ratings.
