INTRODUCTION
Without doubt, power interruptions cause major problems for home and business
computing. An unpredictable power supply can lead to worrying problems such as
surges, spikes, lightning strikes, brown-outs, power-cuts (black-outs), power-back
surges, mains over-voltage, and complete failure - all of which can damage electrical
and electronic equipment. If any of these should occur, there’s a strong chance you
will suffer from loss of critical data, lowered productivity and even damage to your
expensive equipment.
Sollatek encompasses a wide range of power protection products for use in many
different industries where clean, regulated mains power is critical to their continued
operation.

AVS13 micro, AVS13 RL micro, AVS15 micro
The AVS is an Automatic Voltage Switcher rated at 13 Amps
(AVS13) or 15Amps (AVS15). The AVS will switch off the equipment
connected to it if the mains power goes outside preset acceptable
limits and will re-connect -automatically* - when the mains power
returns to normal. Re-connection takes place after a delay to ensure
stability of the mains.
This new version of the AVS has a built-in micro-processor that has
added advanced features to the product. These include;
* unless set to MANUAL on the Time delay Dial
2) Time Delay dial
By adjusting the dial, you can set the start-up delay (after first connecting and after re-connection
in case of over or under-voltage) from 15 Seconds to 3 minutes (AVS13) or 1.5 minute to 5 minutes
(AVS15). Alternatively you can pre-set to MANUAL. MANUAL indicates that the AVS will not connect
your load until you press the LOAD ON/OFF switch.
Tip: Use MANUAL setting if you do not want equipment to automatically re-start for example if you
do not wish the Air-conditioner to re-connect automatically after a power cut.
3) LOAD ON/OFF Switch
Using this button, you can switch your equipment on or off. If the switch is in the off position
(Light bulb off), press the switch to turn the equipment on. PLEASE NOTE THAT THE EQUIPMENT
WILL BE CONNECTED AFTER THE DELAY HAS PASSED AS SET BY THE TIME DELAY DIAL.
SPECIFICATIONS
1) Five voltage indicators
The power supply is good and the load is connected
The AVS has detected that the mains voltage is too high
and therefore dangerous to your equipment. The AVS
has disconnected the power supply .
Power supply has returned to normal (after an over-
voltage condition - see above). The AVS is waiting before
the power supply is restored to your equipment.
Power supply has returned to normal (after an under-
voltage condition - see below). The AVS is waiting before
the power supply is restored to your equipment.
The AVS has detected low voltage condition and has
disconnected the power to your equipment to protect
against it.
Hi
Lo
OPERATION:
1. Make sure that your load does not exceed the rating of the AVS.
2. The limits of the AVS are pre-set at the factory (i.e. The AVS13 is 185-260 volts).
If different limits are required, please refer to your dealer.
3. The AVS15 is supplied with a lead only. Connect a suitable plug and fuse to the lead, and plug in
to the mains.
4. Plug your appliance into the AVS.
5. The LEDs on the front indicate the state of the AVS (see facing page for full details).
6. It is recommended that the AVS is kept switched on, and the appliance switched on and off to
prevent activating the time delay every time the appliance is switched on.
7. The plug connected to the AVS13 is fused at 13Amps. If the unit stops working and no LEDs are
lit on the front of the unit check that the fuse is intact. If not, replace with a 13Amp HBC fuse.
The AVS15E has a 18amp circuit breaker located on the side of the unit. Press to reset.
Caution: Before replacing fuse or resetting the circuit breaker, ensure that the load does not exceed
the recommended rating of the AVS.

AVS30 micro
The AVS30 micro is an Automatic Voltage Switcher rated at 30 Amps. The
AVS will switch off the equipment connected to it if the mains power goes
outside pre-set acceptable limits, and will reconnect automatically when
the mains power returns to normal. Reconnection takes place after a
delay, to ensure stability of the mains.
The new version of the AVS has a built-in microprocessor that adds
advanced features. These include:
By adding microprocessor control to the AVS30, you can enjoy advanced functions which include;
* Variable time delay
* Variable Low voltage disconnect level
* Variable High voltage disconnect level
* Variable Blind time. Response time to under voltage disconnect.
All these new features can be set at installation time.
* The AVS30 Micro has a reset button on the front panel. This button will eliminate the delay time.
* 5 LEDs to indicate the state of the mains supply.
OPERATION
1. Make sure that your load does not exceed the rating of the AVS which is 30Amps.
2. The limits of the AVS as a standard are set for a window of 190-260 volts.
3. The AVS has to be wired to the mains supply and to the equipment it is supplying.
Please refer to the wiring diagram on page 9.
4. On first switching on, there will be no output for the wait time of approximately three minutes
while the AVS monitors the mains.
a) To by-pass the wait time, press the re-set button on the front panel of the AVS30.
b) If a different wait time is required, then change the settings on potentiometer marked
WAIT. Settings are available in increments up to 10 minutes.
You can also set the WAIT dial to MAN. While on MAN the AVS30 will not reconnect the mains
unless the Reset button is pressed. For that period the yellow LED indicates that the mains are
within acceptable limits, after which the green LED goes on and the load is connected.
5. A different blind time can be set if a different undervoltage disconnect limit is required.
Under voltage blind time means the AVS ignores any undervoltage conditions during this time.
The AVS will not switch off unless the under voltage last longer than the blind time.
6. It is recommended that the AVS is kept switched on, and the appliance switched on and off to
prevent activating the time delay every time the appliance is switched on.

AVS3P-0
The AVS3P-0 is an Automatic Voltage Switcher designed to protect three
phase loads from voltage fluctuations, over voltage, under voltage, surges,
dips and frequent start/stops. The output is a single volt-free changeover
contact, rated at 16A. This is intended to control an external contactor,
control circuit, start/stop system or alarm. If the voltage on any one phase
goes above or below the pre-set limits (the ‘window’), then the AVS
will switch off. Once the voltage returns within the window limits, the
AVS will wait for a pre-set time, continuing to check the voltages, before
automatically turning the load back on. The over voltage, under voltage
and delay settings are all adjustable using controls in the terminal compartment of the AVS3P. The
standard window that is considered acceptable is 185V-260V(320V-450V three phase). Outside these
limits electronic and electrical equipment are likely to be damaged.
OPERATION
Connect the AVS in accordance with the wiring diagram opposite (fig 1). Ensure that the R, S
& T sensing connections to the AVS come from the supply side of the contactor. Note: a good
neutral connection must be provided from the supply.
The output from the AVS is a changeover relay with volt-free contacts. There is a common (C),
a normally open (NO) and normally closed (NC) contacts. When the AVS3P-0 is in the Red or
Amber condition then C is connected to NC. When the AVS3P-0 displays Green then C is
connected to NO. Make sure that the control current you wish to switch does not exceed the
rating of the AVS3P-0 relay (max 16Amps).
If the AVS is the only thing to control the contactor (or load, or alarm, etc), then the ‘C’ and ‘NO’
AVS contacts can be used to connect power to the contactor coil (method A). If however, there
are other circuits/equipment that also must control the contactor, then the AVS contacts can be
used to interrupt the contactor coil supply from there (method B) or used in conjunction with a
start/stop or other system, e.g. method C.

Set limits of the AVS3P-0 using the thumb-wheel adjustment inside the terminal compartment.
See fig 2. Ensure that limits set are safe for the load being protected. For example: Low =185V
and High = 260V is normally considered safe for most equipment but you should check with the
equipment manufacturer’s information.
Set the time delay control using the thumb-wheel adjustment inside the terminal compartment.
This will depend on your load and how it is operated. As a general guide, compressors and
refrigeration equipment will need at least 3 minutes; motors, pumps, etc should not be started
too frequently so may be 2 minutes minimum, electronic loads 0.5 minutes. The ‘Off’ position
gives just 10 seconds. The equipment manufacturer should be consulted on the best setting.
At first switching on, there will be no output during the Delay period. For that period the yellow
LED indicates that the mains supply is within acceptable limits, after which the green LED goes
on and the output relay changes state to turn the load on.

AVS303
The AVS303 is a Three Phase Automatic Voltage Switcher which
protects against over voltage and under voltage on any one of the
three phases as well as loss of one or more phases. Indication and/or
disconnection as a result of mains frequency error of phase sequence
error is available as an option.
The VS303 incorporates a contactor to switch the full load current.
The AVS303-xx is available in different sizes ranging from 23Amps to
1250Amps (the -xx relates to the model number, ie: AVS303-23 is a 23Amp
per phase AVS303).
The options for the AVS303 are:
Frequency error (OPT/01)
Phase sequence error (OPT/02)
Or both (OPT/03)
OPERATION
Make sure that your load does not exceed the rating of the AVS303.
The limits of the AVS303 are set for a window of 190-260 volts line to neutral. If a
different window is required, please refer to your dealer.
If an option board is fitted please ensure the d.i.l. switches are set correctly as
detailed in the separate instructions.
Connections of the three phases from the mains (INCOMING CABLE) and to the
load (OUTGOING CABLE) are made to the contractor.It is essential that the incoming
NEUTRAL is connected to the terminal block.
On first switching on, there will be no output for approximately one minute while
the AVS303 monitors the mains. For that period the yellow LED indicates that the mains are
within acceptable limits, after which the green LED goes on and the load is connected. The red
LED indicates that the mains is outside the window, and the load is disconnected.
Frequency and Phase Error indications, where fitted, are by separate red LEDs.

POWER PROBLEMS
AND THEIR ASSOCIATED CAUSES
All electrical and electronic equipment, connected to the mains supply is at risk of
being damaged from spikes, surges, lightning, brown-outs, power-cuts (blackouts),
power back surges, and over-voltage. The following is a summary of the main types of
power problems, causes and how these affect electrical and electronic equipment.
Spikes/Surge: Very short, (one millisecond) event of very high surge in voltage to
thousands of volts and amps. Spikes are common in all parts of the world and repeated
exposure to spikes will damage electronic equipment and corrupt data.
What causes it? Switching on/off of nearby equipment, lightning, motors starting etc.
RFI (Radio Frequency Interference)/Noise: High frequency disturbances that occur
within a short period of time (milliseconds). RFI & noise are very common in all parts of
the world and are the main cause of data corruption.
What causes it? Generated by high frequency noise from nearby equipment like
TV, radio equipment, transmitters, mobile phones, switching on/off of certain loads,
fluorescent lights, motor speed controls, light dimmers.
Over-Voltage: Long duration (milliseconds, seconds, minutes, hours or days) rise in
the voltage above acceptable limits. Depending on the level of the over-voltage, the
damage can be instantaneous, severe and irreparable.
What causes it? On return of mains supply after power cuts, under-sized utility
oscillating between periods of brown-outs and over-voltage or accidental (e.g.
accidental connection between two phases).
Brown-Out: Long duration of low voltage (milliseconds to seconds, minutes, hours or
days). Very common in parts of the world especially where the power utilities are over-
stretched. Prolonged and frequent brownouts cause the equipment to malfunction
or not work at all. Repeated episodes are certain to cause damage. Motors and
compressors (and therefore fridges, freezers, coolers, air-conditioners and pumps) are
especially at risk. In time, damage is certain.
What causes it? Most commonly an over-stretched utility, especially in areas of poor
power distribution infra-structure and remote areas. Common in dry seasons where
water is used for electricity generation.
Basic Lightning: Direct or nearby strikes can cause minor problems or severe
disturbances and damage. Lightning produces spikes/surges, over-voltage or power
cuts.
What causes it? The surge is generated by either a direct hit, or indirectly striking
underground or overhead lines and transmitting high surges to connected equipment
in nearby buildings.
Power-cuts: Common in many countries in the world, especially in areas of frequent
voltage problems. Sudden loss of power can cause damage ranging from corruption
of data to mechanical faults as equipment is stopped while in operation.
What causes it? Power or sub station failure, breakdown in the distribution network,
or simply a plug being pulled out accidentally.
Power-Back Surges: These typically occur when power returns after a power-cut
and connected equipment receives a surge of electricity at an over-voltage level,
which can be very damaging (see above).
What causes it? Power back surges are created by the utility, when it restores
supply at an above normal voltage in order to compensate for the demand as
connected equipment re-starts simultaneously.
Telecom surges, spikes and lightning: Short term, high voltage and current
phenomena occurring on the telephone lines. Can cause irreparable damage to any
piece of equipment connected to the incoming line. The telephone line itself may
even be damaged or destroyed in severe cases.
What causes it? Telecom spikes are caused by lightning striking either the telephone
line directly or an object near it.
