The 16" 18 gauge
wires shown below
are needed for the
outputs to share
the load when
connected in parallel
for full power.
Amps available on the 24vdc. Figures 1 - 4 illustrate
each of these four hookups for the SPS-20. Charging
two 12v batteries independently is also a very big
benefit for long battery life.
Specifications/Instructions
AC Input: L, N, G - 3P Terminal block
Safety Cover, snap or hinge is provided
L= Line, N= Neutral, and G = Ground
The G terminal must be connected to Earth Ground.
Optional 3 wire line cord P/N: ..................... HA-LC3SZIP
AC input/Hz/Watts default ...... 90-132vac/47-63Hz/400w
AC input/Hz/Watts
(set 240) .. 133-250vac/47-63Hz/400w
UL evaluated at 60Hz 120/240vac
Caution: Never apply 240vac when AQM20 is set for
120vac this will void warrantee and damage unit.
The AC input default is 120vac. You can cut the PCB
trace marked “CUT 240” on the bottom of the PCB
under the input inductor above and toward the inside of
the AC input terminal block.
AC LED Indicator (Next to AC Input Terminal Strip)
The AC indicator is a bi-color green and red led. This
led off with AC at the terminals would indicate a blown
fuse link.
A blown AC fuse link would indicate catastrophic
failure and must me returned to the factory for repair.
AC Status Output Relay: 3P Terminal block
AC fail “C” contacts ........................................ 2A/120vac
Three position AC fail terminal block marked “NO, C, NC” are
shown in the Normal, energized, AC ON condition.
DC OUTPUTS: 4P Terminal block (2 per output)
Output-1 & 2 continuous rating .............. 12vdc at 8A ea
Output 1 & 2 Typical Output Voltage .......... 13.72vdc ea
Load regulation no load to max ....................... .25%Typ
AC Line regulation 85-136vac/170-264vac ...... .03%Typ
Each Output ripple & noise at full load ............ 400mv pp
Current Overload Short Circuit Protection .............. Yes
Thermal runaway Protection .................................... Yes
Current Overload and Thermal shutdown will auto-
restart without removing load.
Ambient operating temperature range .. -30

Switching Frequency .......................................... 66KHz
DC LED Indicator

Battery Standby
Two 12” battery cable assemblies that plug from
AQM20 to battery are provided. Red (+) 12vdc,
Black (–)Neg.
Optional 36” battery cable (1) P/N: ............... WA-36IBAT
-Battery(s), any type of lead acid .......... 12v 4AH-100AH
Battery(s) recharge1 & 2 ................ 13.72vdc at 2A max
Battery(s) 1 & 2 recharge PTC self resetting ......... 1.04A
Battery(s) 1 & 2 discharge PTC self resetting ............ 8A
Battery)s) 1 & 2 Reverse hookup protection ............. Yes
In standby mode each battery is limited to 8 Amps of
continuous current. When both outputs are connected
in parallel, and standby current will be greater than 8
Amps, you must use 2 batteries connecting one to
battery 1 and one to battery 2.
Paralleling (2) battery
cables to (1) battery will not double the current .
Review application note 3, Battery Standby table to
calculate battery size.
To estimate the recharge time in hours for depleted
battery(s), multiply the AH rating times 1.2. (AH x 1.2).
As an example, 2 12v 10AH batteries would take about
12 hours to re-charge.
Physical
AQM20 Module Dimensions .. 7.75”L x 4.17”W x 3.23”H
