AQU243-4F, AQU243-8F & AQU126-4F Installation Instructions

AQU243-4F (&-8F) (&-8F) and AQU126-4F Description

The AQU243-4F (&-8F) and AQU126-4F are clean, efficient, heavy duty, low frequency off line switching power
supplies with precision battery charger and power supervision. These supplies are so clean that they can be used
anywhere a linear or switching supply is recommended. The filtering and switching systems we use are very similar
to what you would find on high quality computers. Even though the AQU243-4F (&-8F) (24v) and the AQU126-4F
(12v) are both 100 watt power supplies utilizing the same printed wiring board, we use separate supplies for 12v and
24v models for optimum performance. The universal input of 85vac to 260vac allows them to used anywhere in the
world without adjustments to the power input. The ability to run at very low AC voltages allows the AQU126-4F and
AQU243-4F (&-8F) to tolerate brownouts very well. The AQU243-4F (&-8F) and AQU126-4F are fully self-contained
and isolated from the AC power input line to all world safety standards. Each power supply weighs less than 1.5 lbs
and occupies less than ½ of a cubic foot of cabinet space.

The AQU243-4F (&-8F) and AQU126-4F become an uninterruptible power supply when a stand by battery(s) is
connected with the battery cable provided. These supplies have a special power limiting circuit that allows the
batteries to be float charged across the output without lock up or chirping on and off. The battery(s) is protected with
an automatic resetting circuit breaker and diode for over current and accidental reversed battery hookup. Precision
float charging means faster recovery time and longer life for the battery(s). There is no switch over or voltage drop
when input power fails. Standby battery(s) can be any capacity between 4 and 40 Amp hours. The AQU243-4F (&­8F) 24vdc is rated for 3 Amps continuous current with 300ma reserved for battery charging. The AQU126-4F 12vdc
is rated for 6 Amps continuous current with 500ma reserved for battery charging.

Power Supervision utilizes 2 relays and electronics to indicate 2 levels of the stand by battery. The AC FAIL relay
provides a form C contact set to indicate the AC has failed, the supply is running on standby batteries. The LOW
BAT relay provides a form C contact set to indicate the battery(s) is low, not much stand by power is left. Either of
these form C contacts can be used to signal a buzzer and/or other signaling device. Both of these relays are
normally energized for fail-safe operation.

Battery-Cut Off uses a 3
of it’s service limit, preventing deep discharge that will damage the battery(s). This relay is normally energized as
are the supervision relays.

Explanation of Terminals and LEDs

AC Input Terminals are marked High Voltage (L)ine, (N)eutral, and (G)round. The terminal block and AC LED are

mounted within a high voltage barrier. The terminal block is self-clamping and can accept wires from 12awg to
18awg.

AC LED adjacent to the AC input terminals is ON Green when AC is applied.
AC FAIL Terminals NO-Normally Open, C–Common, and NC–Normally Closed. The normal relay position

indicates the AC power is on and the relay is energized. The terminal block is self-clamping and can accept wire
from 14awg to 24awg. The contacts are rated for up to 2A resistive load to 120 volts. When the AC fails the relay
drops off normal. AC fail is detected by a small drop in output voltage equating to about 99% battery capacity.

LOW BAT Terminals NO-Normally Open, C–Common, and NC–Normally Closed. The normal relay position is
energized and indicates the output battery voltage is in the normal range. When stand battery(s) reach a low level,
the relay drops off normal.

DC Output Terminals on the AQU243-4F (&-8F) and AQU126-4F are marked (–1+) for dc output number 1, and (–
2+) for dc output number 2 repeating through 4. Each of these outputs are class II power limited with PTC auto
resetting circuit breakers. (Note: Output #1 of AQU243-4F (&-8F) is not class II power limited). You must keep a
.25” minimum spacing of power-limited wires to non-power limited wiring. See specifications and door label for
current ratings. The terminal block is clamping and can accept wires from 14awg to 24awg.

DC Output LEDs are adjacent to each output are ON Yellow when output is ON. If a circuit is overloaded and
tripped, the associated LED will be off.

DC Power LED adjacent to battery connector is ON Red when main DC is on.
Battery Connector is marked –Bat+. This is a .156” 2 position header with lock. The provided battery cable plugs

in to this. The provided cable is 12” long. For remote battery mounting, a 36” battery cable is available, part WA­36IBAT. The battery cable wires are Red and Black. The red connects to the positive and black to the negative of
the battery. The AQU243-4F (&-8F) 24vdc model comes with a 12” black wire with female slip on connectors on
each end for connecting 2 12v batteries in series.

Maintenance

The power supply and stand by battery(s) should be tested at least once a year as follows:

1. Check LEDs for normal state. AC ON Green, Output ON Yellow, DC ON Red.

2. Check output voltage with normal load. The AQU126-4F should read between 13.60 and 13.85vdc. The
AQU243-4F (&-8F) should read between 27.20 and 27.7vdc. This assures proper voltage to float charge
batteries.

3. With normal load, disconnect AC input. AC LED should be off, all other LEDs should remain normal.

4. Check DC Output to be above 12.1vdc for AQU126-4F and 24.2vdc for AQU243-4F. This checks standby
batteries to be operational. Sealed lead acid batteries have a typical life of 3 to 5 years.

5. Re Apply AC and verify AC LED ON.

AQU243-4F (&-8F) and AQU126-4F Multiple Output, Off Line Supervised Power Supply/Chargers

Installation Guide

The AQU243-4F (&-8F) and AQU126-4F Supervised Power Supply/Chargers with standby battery(s) provide an
uninterruptible 24vdc or 12vdc power source. The DC power outputs are class II power limited outputs, each with
PTC circuit breaker protection.

1. This installation should be made by a qualified service person, should conform to all local codes and should
comply with The National Electrical Code (or equivalent).

2. Mount the Power Supply in desired location.

3. Connect DC devices to the Output Terminals. Observe polarity.

4. The power table below shows the continuous current you may use for each output.

5. Be sure that the total current requirement conforms to the total available output current.

6. Connect AC FAIL alarm contacts. N/O means normally open with AC ON.

7. Connect LOW BAT alarm contacts. N/O means normally open with battery voltage normal.

8. Connect Line voltage, 90 to 250vac and Earth Ground to the 3 position terminal block marked HIGH VOLTAGE.
The Earth Ground terminal is connected to the enclosure and outer heat sink case for safety and EMI filtering.

9. Each Output Power/Fuse ready is indicated with a Yellow LED ON centered above each output terminal pair.
See instructions for more details regarding LED indicators.

10. To reset a tripped PTC Circuit Breaker, you may have to correct the fault and remove load for up to 1 minute.
This allows the PTC re-settable fuse to cool and reset to it's normal “ON” condition.
