CAUTION
ATTENZIONE
AVVERTISSEMENT
RISK OF BURNS, EXPLOSION, FIRE,
ELECTRICAL SHOCK, PERSONAL INJURY.
Never carry out work on live parts! Danger of fatal
injury! The product’s enclosure may be hot, allow
time for cooling product before touching it. Do not
allow liquids or foreign objects to enter into the
products.
To avoid sparks, do not connect or disconnect
the device before having previously turned-off
input power and wait for internal capacitors
discharge (minimum 1 minute).
RISCHIO USTIONI, ESPLOSIONE, INCENDIO,
SCOSSA, LESIONI GRAVI.
Non effettuare mai operazioni sulle parti sotto
tensione! Pericolo di lesioni letali! Il contenitore
può scottare, lasciar quindi raffreddare il
dispositivo prima di toccarlo. Non far entrare
liquidi o oggetti estranei nel dispositivo.
Per evitare scintille, non collegare o scollegare
l'apparecchiatura prima di avere tolto tensione di
ingresso e prima che sia avvenuta la scarica dei
condensatori interni (min. 1 minuto).
RISQUE DE BRULURES, EXPLOSION,
INCENDIE, ELECTROCUTION, DOMMAGE AUX
PERSONNES.
Ne jamais effectuer des opérations sur les parties
sous tension! Danger de mort! Le récipient peut
produire des brulures, le laisser refroidir avant de
toucher l'appareil. Ne faites pas pénétrer des
liquides ou des corps étrangers dans l'appareil.
Pour éviter des étincelles, ne pas connecter ou
déconnecter l'équipement jusqu'à ce que vous
avez supprimé la tension d'entrée et avant qu'elle
n'ait lieu de décharge des condensateurs internes
(minimum 1 minute).

INSTALLATION INSTRUCTION

USER INSTRUCTIONS
1) DESCRIPTION
DIN rail mountable primary switched-mode power supply with 90 - 264 VAC (110 - 345 VDC) input, suitable for single phase mains line and DC line.
2) INSTALLATION
Use DIN-rails according to EN60715. Installation should be made vertically (see Fig.4). For better device stability fix the rail to the wall close to the point
where the device is to be mounted. In order to guarantee sufficient convection, we recommend observing a minimum distance to other modules (see
Fig.3).
The device is provided with a thermal protection; a limited air flow can cause the thermal protection tripping.
The SMPS automatically restarts after cooling. To get normal operation reduce the temperature of 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 disconnect the connectors before having previously turned-off
input power and waited for internal capacitors discharge (minimum 1 minute)
In order to comply with UL certification, use appropriate copper cables of indicated cross section, 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 wires according 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 is provided with internal fuse 2AT / 250 VAC thus an external short circuit/overcurrent
protection must be provided by the end user (see Fig.6).
For operation on a single-phase system, a protection fuse on the phase must be 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 line with rated Vin 120 - 240 VAC (see Fig.7).
6) DC INPUT CONNECTION
Connect L terminal to (+) positive pole, N terminal to (-) negative pole. Rated voltage 110 –345 VDC.
The device is also suitable for photovoltaic or wind turbine applications (see Fig.7).
7) OUTPUT CONNECTION
The device is suitable for SELV and PELV circuitry.
Vout can be adjusted with a potentiometer to a wide range (see Fig.1), only on Models LDN40-515, LDN40-12 and LDN40-12D.
Check Vout before connecting the power supply 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.
Vout must be set uniformly (±100 mV) on each power supply and the wiring must be symmetrical to ensure an equal current distribution.
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 1.5 with constant output voltage. If the current is In x 1.5 the unit enters the OL protection and starts an ON/OFF cycle
(hiccup mode).
SC behaviour: the device supplies the indicated short circuit peak current for 30 ms if the output current exceeds In x 1.5 the device enters into a
controlled ON/OFF cycles (hiccup mode). The output voltage drops to a voltage value depending on the impedance of the failed load circuit.
Output OV circuit protection: the output is protected against potential OV due to internal malfunction or coming from the load for
Vout Vnom x 1.2 –1.3, depending on the model.
OT protection: turns off the device if the internal temperature exceeds a safe limit.
The device restarts automatically after cooling down. To recover to normal operation reduce air temperature surrounding the power supply, increase
cooling or reduce load (see Fig.8).
10) FEEDING DC MOTORS
It is possible to feed DC motors considering that when a motor starts-up under effort its consumption is much higher than the nominal current and it can
trigger overcurrent protection (see accessory device).
NOTE: motors can generate high conducted noise on the DC line. Therefore, it is not recommended to feed on the same line motors and equipment
sensitive to noise.
