USER INSTRUCTIONS
1) Description: DIN rail mountable primary switched-mode power supply with 90...264Vac (110…345Vdc) input, suitable for Single phase main line and DC line.
2) Installation: use DIN-rails according to EN60715.Installation should be made vertically(see Fig.4). Forbetter device stability fix the rail to the wall close to the point where
the device isto be mounted. In orderto guarantee sufficient convection, we recommend observing aminimum distance to other modules (see Fig.3).
The device isprovided with a thermal protection; a limited air flow can cause the thermal protection tripping.
The SMPS automatically restartsafter cooling. To get normal operation reduce the temperatureof the air surrounding the power supply, increase the ventilation or reduce the
load (see Fig.8)
3) Connections: the device is equipped with screw terminal blocks.To avoid sparks, do not connect or disconnectthe connectors before having previouslyturned-off input
power and waited for internal capacitorsdischarge (minimum 1 minute)
In order to complywith UL certification, use appropriate copper cables of indicated crosssection, designed for an operating temperatures of:
60°C for ambient up to 45°C
75°C for ambient up to 60°C
90°C for ambient up to 70°C
Strip the connecting ends of the wiresaccording to the indication and ensure that all strands of a stranded wire enter the terminal connection (see Fig.5)
4) Input protection: the device input is provided with varistors against overvoltage. Input isprovided with internal fuses 1AT/250Vac, thus an external short circuit/overcurrent
protection mustbe provided by the end user (see Fig.6).
For operation on a single-phase system, a protection fuseon the phase mustbe provided.
Surge protection: it is strongly recommended to provide external surge arresters (SPD) according to local regulations.
5) AC input connection: the device can be connected to single-phase AC lines with Uin 120…240Vac (see Fig.7).
6) DC input connection: connect L terminal to (+) positive pole,N terminal to (-) negative pole. Rated voltage 110...345Vdc.
The device isalso suitable for photovoltaic or wind turbine applications (seeFig.7).
7) Output connection: The device is suitable for SELV and PELV circuitry.
Check Uout before connecting the powersupply to the load. With output voltage set to the max. value, the continuous [current x voltage] must not exceed the nominal power.
8) Parallel connection and redundancy: power supplies can be connected in parallel to increase power.
For redundant connection, use an external isolating device must be used (see accessory device).
9) Output protection: the device is protected against overload (OL) / short circuit (SC) / overvoltage (OV) / overtemperature (OT).
OL and SC: are controlled by a hiccup mode auto-reset protection with the following behaviour.
OL behaviour: Max. OL = In x 1.6 with constant output voltage. If the current is In x 1.6 the unit enters the OLprotection and startsan ON/OFF cycle (hiccup mode).
SC behaviour: the device supplies the indicated short circuit peak current for 40ms ifthe output current exceeds In x1.6 the device entersinto a controlled ON/OFF cycles
(hiccup mode). The output voltage drops to a voltage value depending on the impedanceof the failed load circuit.
Output OV circuit protection: the output is protected against potential OVdue to internal malfunction or coming from the load for Uout Unom x 1.2 – 1.3, depending on the
model.
OT protection: turns offthe device if the internal temperature exceeds a safe limit.
The device restarts automatically after cooling down. To recover to normal operation reduceair temperature surrounding the power supply, increase cooling orreduce load
(see Fig.8).
10) Feeding DC motors: it is possible to feed DCmotors considering that when a motor starts-up under effort itsconsumption is much higher than the nominalcurrent and it
can trigger overcurrent protection (see accessory device).
NOTE: motors can generate high conducted noise on the DC line. Therefore itis not recommended to feed on the same linemotors and equipment sensitive to noise.
