Fuse 6A/250V AC Input Fuse
6A/250V PTC fuse protects power module from AC line power
spikes.
CAUTION: Fuse is not field replaceable
LNG
AC –In
Terminal Block
A 3-wire terminal block for AC power input.
Handles 110-240 VAC. Accepts wire gauge 12AWG to 18AWG.
L= Line (+) N=Neutral G=Ground
AC LED
AC Power
Indicator
Green LED indicator is lit when AC power from AC circuit or
battery is ON. Indicator may be on board or on exterior of
enclosure.
AC FAIL AC Status Relay
A 3-wire terminal block providing a SPDT-Form C contact that
changes state when the AC power is interrupted. Provides
2amp@120VAC output for triggering alert notification
NO = Normally Open C = Common NC = Normally Close
When energized switch is NO/C open, C/NC closed. During power
loss, the switch changes state with NO/C closed and C/NC open.
TROUBLE Low Battery Relay
A 3-wire terminal block providing a SPDT-Form C contact that
changes state when battery voltage drops to 12.1VDC/24.2VDC.
Provides 2amp@120VAC output for triggering alert notification
NO = Normally Open C = Common NC = Normally Closed
The switch is NO/C open when energized, C/NC closed when
energized. During power loss, the switch changes state with NO/C
closed and C/NC open.
PWR LED
Battery Power
Indicator Green LED indicator is ON when AC or battery power is present.
OFF indicates AC fail with low or no battery power.
-DC OUT+
DC-Out
Terminal Block
A 2-wire terminal block for DC output voltage to devices, power
distribution or accessory board. DC output is Class 2 power
limited and accepts 10AWG to 24AWG wire.
12V 24V 12/24vdc switch Toggle switch allows field selection of 12VDC or 24VDC output.
-BAT+
Battery Backup
Plug
A 2-pin plug for connecting battery cables for uninterruptable
battery backup.
DC LED
DC Output Power
Indicator
Red LED indicator is lit when DC power is ON.
+LTW
Battery Limited
Time Warning
2 position header providing an open collector output from the
negative position to annunciate low battery. Default position is
Normally Open. Circuit closes to trigger a signal when battery falls
to 95% depleted. Terminal accepts 22AWG to 30AWG wire.
3. Select Output Voltage
Determine voltage of devices that will be powered by the power supply unit. The AQD5 provides
5 amps continuous output at 12VDC or 3 amps @ 24 VDC.
To select voltage, slide switch in the direction of the desired voltage.
CAUTION: ENSURE AC POWER, BATTERY AND OUTPUT LOAD ARE DISCONNECTED
BEFORE CHANGING SETTING . Ensure that the battery voltage matches the power
supply output voltage before connecting batteries.
