INSTRUCTION MANUAL

DESCRIPTION

The automatic phase switch APM-20 is

designed to ensure uninterrupted power

supply of a one-phase receiver in case
of phase loss or RMS voltage value de­crease below the norm. The main ad­vantage of the device is a small relative

voltage measurement error, which does

not exceed 1% even for highly distorted
waves. The above is a result of an im­plementation of the True RMS converter.
The APM-20 device is supplied by three

phases L1, L2, L3 with the L1 phase as
the prior one. The voltage switch thre­shold (180 V AC), switching time (150
ms) and voltage hysteresis (10 V AC)

have default settings and cannot be
changed by a user. Each phase parame­ters are optically signalled by means of

LEDs on the front panel of the device.

The internal system of output contacts
assures an increased resistance to their
bonding and protects against phase-to-

-phase short circuit. The maximum out­put capacity should not exceed 16 A for
AC1 class receivers. APM-20 is mounted
in distribution boards (TH35 rail). The ca-

sing has the width of 2 modules.

FEATURES

● maintaining uninterrupted power sup­ply of a single-phase receiver,

● three-phase power supply L1-L2-L3

(L1-priority phase),

● automatic phase switching during po­wer supply failure or its value decre­ase below 180 V AC,

● switching time at a level of 150 ms

● voltage switch threshold, switching

time and voltage hysteresis have de­fault settings and cannot be changed
by a user,

● high voltage measuring accuracy – re­lative error < 1%,

● voltage measurement of distorted si­gnals (True RMS),

● output load– maximum 16 A for AC1

loads,

● signalling the parameters of particular
voltage supply phases – 3 x LEDs,

● mounting in distribution boards (TH35
rail) – width of 2 modules.

MOUNTING

CONNECTION

1. Disconnect power supply by the phase

fuse, the circuit-breaker or the switch-

-disconnector combined to the proper
circuit.

2. Check if there is no voltage on connec­tion cables by means of a special me­asure equipment.

3. Mount the APM-20 device on the TH35
rail.

4. Connect the cables with the terminals in
accordance with the installing diagram.

5. Switch on the power supply from the

mains.

6. Check if the device operates correctly.

FUNCTIONIG

After power supply is applied, the device is ready to operate. If the voltage on the L1 phase
is higher than 180 V AC, then the receiver is supplied from another phase. If the voltage on
the L1 drops below 180 V AC, then there is an automatic switch to the L2 phase in <150
ms. Analogically, if the L2 phase voltage drops below 180 V AC, then there is an automatic
switch to the L3 phase. In case the L3 phase voltage is below 180 V AC, there is a power
supply switch off for the receiver connected to this output. If the given phase is switched off
due to a voltage drop of <180 V AC, then it is switched on again at a value of >190 V AC
(hysteresis 10 V). The L1 is the priority phase. In case its parameters are correct, then this
phase will supply the receiver. For example, if a receiver is supplied by the L3 phase and, at
the same time, the L1 has correct parameters again, then an automatic switch to the L1 pha­se supply will occur. If the voltage on a particular phase is >180 V AC, the appropriate LED
switches on. This LED switches off if voltage drops below 180 V AC. The phase switching
on and switching off times are the same and equals about 150 ms.

CAUTION

The device is designed for single-pha­se installation and must be installed

in accordance with standards valid in

a particular country. Installation, con­nection and control should be carried

out by a qualied electrician staff, who
act in accordance with the instruction

manual and the device functions. In
case of casing dismantling, the guaran­tee is lost and an electric shock may
occur. Before installation make sure
the connection cables are not under
voltage. The cruciform head screwdri­ver 3,5 mm should be used to install
the device. Improper transport, stora-

ge, and use of the device inuence its
wrong functioning. It is not advisable
to install the device in the following

cases: if any device part is missing
or the device is damaged or defor­med. In case of improper functioning
of the device contact the producer.
