Data Sheet

Input:
• 120VAC, 60Hz, 3.5 amp.
• Input fuse: 5A/250V.
Output:
• Eight (8) PTC protected power-limited outputs.
• 12VDC or 24VDC selectable output.
• 12VDC or 24VDC @ 4.0 amp supply current.
• Outputs are rated @ 2 amp.
• Auxiliary power-limited output
rated @ 1 amp (unswitched).
• Overvoltage protection.
Battery Backup:
• Built-in charger for sealed lead acid or gel type batteries.
• Maximum charge current 1.54 amp.
• Automatic switch over to stand-by battery when
AC fails. Transfer to stand-by battery power is
instantaneous with no interruption.
Supervision:
• AC fail supervision (form “C” contacts).
- Notification trigger is selectable for
30 seconds (factory set) or 2 hours.
