Product Description
The FPT500.245-034-106 is a stand-alone power supply for three-phase mains systems, which
provides a stabilized and galvanically separated PELV/ES1 output voltage at 2 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.
The device is designed as “Class of Protection I” equipment according to IEC 61140. Do not use
without a proper PE (Protective Earth) connection.
For TN,TT mains systems with earthed neutral and IT star mains systems with insulation monitoring
the device is designed for overvoltage category III zones up to 2000m (6560ft) and for overvoltage
category II zones up to 5000m (16400ft). For TN, TT, IT delta mains systems or IT star mains
systems without insulation monitoring the device is intended for overvoltage category II zones up to
2000m (6560ft).
The device is designed to be safe in case of a single phase loss and does not require an external
protection.
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 is required and the operation is limited according mains systems description above.
Keep the following minimum installation clearances: 50mm on top and bottom, 10mm on the front and
10mm left and 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.
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 parallel devices or outputs for higher output currents.
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.
The device is designed to operate in areas between 5% and 95% relative humidity.
Do not connect the negative potential of any output to PE.
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. Feed-back energy
from a load must be below 4J.
The green Status LED reports an output above 90% of the adjusted voltage of a running device and all
three phase voltages are present.
The contact of the DC-OK relay is closed when the DC-OK LED is on.
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 500W. 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 / down buttons you can be changed to output
voltage to the values indicated by a 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 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 other 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 standard M12 S-coded female plug to connect to the input voltage connector (X1). The Pin
assignment is Pin 1 for L1, Pin 2 for L2, Pin 3 for L3 and The Pin with the PE symbol for PE.
Use a standard M12 A-coded 5 pin female plug to connect to the DC OK signal connector (X2). Pin
assignment for (X2): Pin 1 and Pin 4 for relay contact.
Use standard M12 L coded male plugs for the output voltage connectors(X3, X4).
Pin assignment X3 (X4) is Pin 1 is 24VDC Out1(2); Pin 2 is 0V DC Out1(2);
Pin 3 is 0V DC Out1(2); Pin4 is 24V DC Out1(2); Pin5 is PE;
