FPS300.245-049-102 Installation Manual
Product Description
The FPS300.245-049-102 is a stand-alone power supply for single phase mains systems, which
provides a stabilized and galvanically separated PELV/ES1 output voltage at 3 outputs. The negative
potential of the outputs is permanently connected to PE within the unit.
The housing is rated as IP65 and IP67 according IEC60529 and provides protection against electrical,
mechanical and fire hazards.
Intended Use
This indoor use device is intended for commercial use, such as in industrial control, process control,
monitoring, measurement or the like.
Do not use this device in equipment, where malfunctioning may cause severe personal injury or
threaten human life, without additional appropriate safety devices, that are suited for the end-
application.
If used in a manner outside of its specification, the protection provided by the device may be impaired.
Installation Instructions
Install the device with the terminals on the bottom of the device. Other mounting orientations require a
reduction in output current.
When installing watch out for the risk of injury from sharp edges and assure that when installed any
sharp edges on the back cannot be accessed and cannot cause injury.
Use 4 screws ( 2 on top and 2 on bottom mounting holes) suitable for the underground and a strength
comparable to M4 or UNC 8-32 screws.
The device is designed for pollution degree 3 areas in controlled environments.
The enclosure of the device provides a degree of ingress protection of IP65 and IP67 when installed
with all mating connectors firmly connected. Assure that during installation no moisture or dirt gets into
the connections. Operation in wet locations or in areas where moisture or condensation can be
expected is possible.
The isolation of the device is designed to withstand impulse voltages of overvoltage category III
according to IEC 60664-1.
The device is designed as "Class of Protection I" equipment according to IEC 61140. Do not use
without a proper PE (Protective Earth) connection.
The device is suitable to be supplied from TN, TT or IT mains networks. The voltage between the input
terminals and the PE potential must not exceed 264Vac.
The device is designed for convection cooling without a fan. Do not obstruct airflow.
The device is designed for altitudes up to 5000m (16400ft). Above 2000m (6560ft) a reduction in
output current and overvoltage category is required.
Keep the following minimum installation clearances: 30mm on top and bottom, 10mm on the front, the
left and the right side.
The device is designed, tested and approved for branch circuits up to 20A (UL) and 32A (IEC) without
additional protection device. If an external fuse is utilized, do not use circuit breakers smaller than 6A
B- or C-characteristic to avoid a nuisance tripping of the circuit breaker. For DC supply voltages above
150Vdc an external circuit breaker (rated 6A with B- or C-characteristic) is required.
Make sure that you only use plugs and cables rated for the device output current and the required
temperature range. Follow all local and national codes for installation.
Do not connect outputs or devices in parallel for higher output currents.
Do not connect the negative potential of any output to PE.
The maximum permissible ambient air temperature is +70°C (+158°F). The operational temperature is
the same as the ambient or ambient air temperature and is defined 2cm below the device.
Cleaning only with a damp cloth.
Functional Description
The output is electronically protected against no-load, overload and short circuit and can supply any
kind of loads, including inductive and capacitive loads. If capacitors with a capacitance >20mF are
connected to one output, this output might switch off after turning the unit or the output on or
connecting the load.
Do not apply return voltages from the load to the output terminals higher than 35V.
The green Status LED reports an output above 90% of the adjusted voltage of a running device and
no output tripped due to overcurrent or overtemperature.
The OUT-OK contact is closed when the Status LED is green and all outputs according settings.
Contact ratings: 60Vdc 0.3A, 30Vdc 1A, 30Vac 0.5A for resistive loads.
The device has an internal overtemperature protection. If the temperature is too high the unit shuts
down and starts automatically again after cooling off.
Each output will get the same state as before the shutdown.
In case of an internal defect, a redundant circuit limits the maximum output voltage to 32.5V. The unit
shuts down and automatically attempts to restart.
LED bargraph and push-buttons:
The LED bar normally displays the actual output power as percentage value. 100% equals an output
power of 300W. LEDs up to and including 100% are green, the LEDs above 100% are orange. With
pressing the up / down buttons you can see the percentage of each output. The orange LED indicates
the selected output. If you press the "Set Mode" button for 3 seconds all LEDs light up briefly and one
LED stays on, showing the actual output voltage. With pressing the up or down button you can change
the set voltage to the values indicated by the green LED. All orange LEDs are dark. The voltage is set
immediately and the value stored until the next change. If you press the "Set Mode" button again you
can set the output current limit for the selected channel indicated by the orange LED. With the up /
down buttons the current limit is changed to the values indicated by the single lit green LED. The value
is stored until the next change. Select o
ther outputs with the “Set Mode” button. Without further
pressing of push-buttons, the LED bar will return from any other mode to normal mode after 15s.
With the buttons at each channel the channel can turned on/off manually by pressing for at least 1s.
Mating connectors:
Use a 3 Pin 7/8” female plug to connect to the input voltage connector (X1).
Pin assignment for (X1): Pin 2 for L, Pin 3 for N, The Pin with the PE symbol for PE.
Use a standard M12 A-coded 5 pin female plug to connect to the OUT-OK signal connector (X2).
Pin assignment: Pin 1 and Pin 4 for relay contact.
Use 4 pin 7/8” male plugs for the output voltage connectors(X3, X4, X5).
Pin assignment: Pin 1 and 2 for plus; Pin 3 and 4 for minus.
