Overview:
These units will convert a 115VAC / 60Hz input, into a regulated 12VDC or 24VDC output up to 6 amp of
continuous load current (see specifications).
Specifications:
• Maximum charge current .7 amp.
• Filtered and electronically regulated outputs.
• Built-in charger for sealed lead acid or gel type batteries.
• Automatic switch over to stand-by battery when
AC fails (zero voltage drop).
• AC input and DC output LED indicators.
• Short circuit and thermal overload protection.
• Complete with power supply, power distribution module
(when applicable), enclosure, cam lock & battery leads.
• Power on-off switch.
Supervised models only:
• AC fail supervision (form "C" contacts).
• Low battery supervision (form "C" contacts).

Installation Instructions:
The unit should be installed in accordance with The National Electrical Code and all applicable Local Regulations.
1. Mount the unit in desired location.
2. Set SW1 on the power supply board to the desired DC output voltage

*Note: P
ower switch is used to disconnect the L (HOT) terminal from the rest of the board. When servicing the unit,
AC mains should be removed.
6. When using stand-by batteries, they must be lead acid or gel type. Connect battery to terminals marked [- BAT +]
(battery leads included). Use two (2) 12VDC batteries connected in series for 24VDC operation.
Note: When batteries are not used a loss of AC will result in the loss of output voltage.
