1.1 PS-1/PSU-1: AC SupplyInput
The AC supply input module provides AC to DC conversion, DC voltages for the backplane, battery
and radio (or an external device), an optional isolated 24 VDC output and various monitoring
functions.
The PSU-1 was manufactured to power a 24 V backplane, 24 V battery and 24 V radio. The PS-1 was
manufactured in two models. PS-1-1: powers a 12 V backplane, 12 V battery and 12 V radio. PS-1-2
(similar to the PSU-1): powers a 24 V backplane, 24 V battery and 24 V radio.
The module has limited charging capacity for externally connected lead acid batteries. The charging
capacity is designed for float operation and short term boost of batteries already charged and in good
condition. Use of this supply on flat or fully discharged batteries may cause damage.
An optional isolated 24 VDC output rated at 10 W (400 mA) is available for powering a limited number
of analog loops or digit input circuits. It cannot be used with inductive loads such as coils, contactors
etc. Power for these is to be provided from a separate supply.
The PS-1/PSU-1 features supply, voltage, current and temperature monitoring circuits that enable the
processor unit to access these as analog and digital points in the system. When the AC supply fails
and the system is powered from external lead acid batteries if connected the voltage monitoring circuit
provides battery cut-off (for battery preservation) when battery cell voltage reaches +10.5 V (12 V
battery) or 21 VDC (24 V battery). The load capacities for each output of the power supply are shown
in the following table.
This module can be installed in any I/O slot of a 3, 6 or 12 slot backplane in a system. Up to 4 Power
Supply modules of any type can be installed in a backplane thus providing redundant and alternative
power source configurations.

PS-1 Battery Charging States
•Charge State: The power supply starts up in the Charge State. In the Charge State the Power
supply will charge the battery with the highest possible current. This current is determined by the
maximum current the power supply can supply and the maximum battery charge current. The
maximum battery charge current is typically 0.25 * the battery capacity. E.g. if the battery capacity is
6.5 AH the maximum charge current will be 0.25 * 6.5 = 1625 mA. To achieve the desired charge
current the supply voltage will be slowly increased. If the supply voltage reaches 14.25 V at 25 °C the
charge mode will be terminated and the Boost mode will be entered.
•Boost State: In the Boost State the supply voltage will be maintained at 14.25 V at 25 °Cas long as
the battery charge current and the maximum supply current are not exceeded. The Boost State lasts
8% of the charging time. If the charging time was less than 12 minutes the Boost State will be skipped
and the Float State will be entered.
•Float State: In the Float State the power supply wants to maintain 13.8 V at 25 °C as long as the
maximum supply current is not exceeded. The voltage will be very slowly decreased from 14.25 V
(Boost/Charge voltage) to 13.8 V. The maximum adjustment rate is one adjustment every 2 minutes.
This is done to let the battery float down to this voltage. The float state is also entered when the
power supply is in Charge or Boost mode and AC power is lost. If the AC power returns, the power
supply will enter the Charge State.
•No Battery State: If the power supply is in any of the above states and the battery current is less
than 10 mA and greater than -10 mA for longer than 5 minutes, then the No Battery state is entered.
In this state the power supply wants to maintain 12.5 V at any temperature. If the battery current
becomes greater than 15 mA or less than -15 mA the No battery state is terminated and the Charge
state is entered.
•Manual State: If the Manual bit in the power supply is set, the Manual state is entered. In Manual
state there is no control except that the supply voltage will be reduced if the maximum supply current
is exceeded. Resetting the Manual bit will cause the power supply to enter the Charge State.

* These voltages are temperature compensated. The voltage shown is the voltage at 25 °C. The
voltages are increased by 22 mV for each degree Celsius the temperature decreases. If the
temperature is 80 °C or -20 °C (minimum or maximum values) the temperature sensor is assumed to
be faulty. An error will be flagged and a temperature of 25 °C will be assumed.

Notes:
•A condition has to be valid for 3 seconds before the trim voltage is adjusted.
•In float state the trim voltage will only be decreased at a maximum rate of once every 2 minutes.
•In every state the maximum supply current is continuously monitored and the voltage is reduced if
exceeded.

1.2 PS-10: AC SupplyInput 90 to 260 VAC
& PS-20: DC Supply Input 20 to 60 VDC
The PS-10 power supply provides AC to DC conversion, DC voltages for the backplane, battery and
radio (or an external device), an optional isolated 24 VDC output and an optional monitoring
processor. The PS-20 power supply offers the same functionality as the PS-10 except it has a DC
supply input instead of an AC supply input.
The PS-10 and PS-20 are manufactured to power a 12 V backplane, 12 V battery and 12 V radio. The
PS-10 and PS-20 are available as a 24 V module by special order (please see below for
specifications).
An isolated 24 VDC output rated at 10 W (400 mA) is an option available for powering a limited
number of analog loops or digit input circuits. It cannot be used with inductive loads such as coils,
contactors etc. Power for these is to be provided from a separate supply.
In addition the module has limited charging capacity for externally connected lead acid batteries. The
temperature compensated charging capacity is designed for float operation and short term boost of
batteries already charged and in good condition. Use of this supply on flat or fully discharged batteries
may cause damage.
When the AC supply fails and the system is powered from external lead acid batteries (if connected),
the voltage monitoring circuit provides battery cut-off (for battery preservation) when battery cell
voltage drops to 10.5 V ± 0.2 V.
The PS-10/20 has an optional monitoring processor that can be factory fitted. This allows battery
voltage, battery current, regulated supply current, and internal or external temperature to be
monitored.
If no monitoring circuit is loaded, the PS-10/PS-20 will not be able to communicate with the processor
module and therefore will not show up in the hardware overview. In addition, there will be no power
supply monitoring information (i.e. indication of battery current, battery voltage, temperature, battery
low, AC present, Aux 24 V present) in the system. On/off control of the radio power and auxiliary 24 V
output power will be under control of the processor module.
A power supply module can be installed in any I/O slot of a 3, 6 or 12 slot backplane in a system. Up
to 4 Power Supply modules of any type can be installed on a backplane thus providing redundant and
alternative power source configurations.

PS-10/PS-20 – Module LEDs
LED Description (when ON)
OK * Module is functioning OK
Vsup AC supply input is powered. For PS-20, ON when DC input circuitry is powered.
Vb Battery voltage supply is OK. This LED should always be on and means that the power
supply is able to charge a battery or is being powered by the battery input.
5 V Internal 5 V supply is OK. This LED should always be on as the 5 V supply is used to
power all the modules.
Vaux Auxiliary 24 V supply is OK (will only display if the 24 V converter is installed).
Controllable if a monitoring processor is fitted.
BATT CHG * Battery is being charged
FL * Battery is in float charge mode
BO * Battery is in boost charge mode
LO *
Battery has reached discharged condition (< 11.5 V± 0.2 V).
LO LED is cleared when battery > 12.4 V ± 0.2 V
* Only enabled when a monitoring processor is fitted (optional for the PS-10 and PS-20)
PS-10/PS-20 - AdditionalFeatures
The PS-10 and PS-20 have an additional DC output for powering low power radios. The connections
are on the DC terminal block. This output is switched off on low battery voltage for battery protection
and can be controlled when the monitoring processor is fitted.
The PS-10/PS-20 is supplied with an internal and external temperature sensor. When a battery is
connected, the external sensor should be mounted close to the negative terminal of the battery to
ensure correct charging operation. The lowest temperature is monitored by the monitoring processor
and used by the temperature compensated battery charging (in normal operation the internal
temperature sensor will indicate a higher temperature than the external sensor).

1.3 PSU-2: DC SupplyInput, 18 to 36 VDC
The PSU-2 DC supply (18 to 36VDC) module provides DC to DC conversion, galvanic isolation,
+12 VDC, +5 VDC and various monitoring functions to power the RTU modules.
An isolated 24 VDC output rated at 10 W (400 mA) is available for powering a limited number of
analog loops or digit input circuits. It cannot be used with inductive loads such as coils, contactors etc.
Power for these is to be provided from a separate supply.
The PSU-2 features optional supply, voltage, current and temperature monitoring circuits that enable
the processor unit to access these as analog and digital points in the system. When the DC supply
fails and the system is powered from external lead acid batteries if connected the voltage monitoring
circuit provides battery cut-off (for battery preservation) when battery cell voltage reaches 10.5 VDC.
The load capacities for each output of the power supply are shown in the following table. Note: the
specifications shown are for the 12 V model of the PSU-2. The PSU-2 was also available as a 24 V
model.

PSU-2 Module LEDs
Three red LEDs labelled +5 V, +12 V and Vs are on when the various power supply sections are
functioning correctly. The Vs LED indicates when the isolated 24 Volt/10 Watt output is activated. This
output is under the main processor control (CP-1 or SBX-2) but is normally in the on state. A green
LED at the top of the face plate is ON when the microcontroller of the monitoring circuit and the power
conversion circuits are operating correctly. An additional four red LEDs labelled CHG, FL, BO and LO
indicate the condition of a connected battery which are:
CHG Battery is being charged
FL Battery is in float charge mode
BO Battery is in boost charge mode
LO Battery has reached its discharged condition (<22 V)
This module can be installed in any I/O slot of a 3, 6 or 12 slot backplane in a system. Up to 4 Power
Supply modules of any type can be installed in a backplane thus providing redundant and alternative
power source configurations.
