Product Description
The FPS300.241-002-101 is a stand-alone power supply for single phase mains systems, which
provides a stabilized and galvanically separated PELV/ES1 output voltage. 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 devices in parallel 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.
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 >100mF are
connected, the unit might charge the capacitor in an intermittent mode.
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.
The DC-OK contact is closed when the Status LED is green.
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 output shuts
down and starts automatically again after cooling off.
In case of an internal defect, a redundant circuit limits the maximum output voltage to 32.5V. The
output 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.
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 predefined values: 24V, 24.5V, 25V, 25.5V, 26V, 26.5V, 27V and 28V as printed aside
the LEDS. The voltage is set immediately and the value stored until the next change. If no button is
pressed for 15s unit returns to the normal state the LED bar will return to show the output power.
Mating connectors:
Use a Harting HANQ4/2 female plug to connect to the input voltage connector (X1). Pin assignment:
Pin 1 for L; Pin 4 for N; Pin PE for PE.
Use a standard M12 A-coded 5 pin female plug to connect to the DC OK signal connector (X2).
Pin assignment: Pin 1 and Pin 4 for relay contact.
Use a Harting HANQ4/0 male plug to connect to the output voltage connector (X3). Pin assignment:
Pin 3 for plus; Pin 2 for minus; Pin 1 and 4 are not connected.
