USER INSTRUCTIONS
1) Description: DIN rail mountable primary switched-mode power supply with 90...264Vac or 110…345Vdc input (UL not evaluated), 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). 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 pluggable screw terminals. 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 fuses 3.15AT/250Vac, 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 lines with Uin 120…240Vac (see Fig.7). Ensure that the PE conductor is properly connected.
Please connect first the PE.
6) DC input connection: connect L terminal to (+) positive pole, N terminal to (-) negative pole and terminal to GND. Rated voltage 110...345Vdc (UL not evaluated).
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.
Uout can be adjusted with a potentiometer to a wide range (see Fig.1).
Check Uout 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.
Uout must be set uniformly (±100mV) on each power supply and the wiring must be symmetrical to ensure an equal current distribution.
Models with “P” suffix have an integrated ORing circuit.
For redundant connection, use the Models “P” or 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 30ms 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 Uout Unom 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.
11) Operation with Battery: when a battery is connected in parallel to the Output for backup purposes (see accessory device).
12) Environmental: these products are IP20 (according to IEC 60529, not UL evaluated), and therefore chemicals/solvents, cleaning agents and other liquids must not be used.
13) Environment: these power supplies are SMPS for use in applications within a Pollution Degree 2, overvoltage category II environment (overvoltage category III according to EN50178).
Do not use in wet area or subject to moisture. These products are designed for indoor use only.
14) Intended use: these are isolated devices suitable for SELV and PELV circuitry and are designed to be mounted on DIN rail and installed inside a protective enclosure. They are
intended for general use such as in industrial control, communication, and instrumentation equipment.
If the power supply is used in a way not specified in this manual, the protection provided by the equipment may be impaired. Don’t use these devices in applications where malfunction may
cause injury or death.
15) Radio interference: this is an electrical appliance according to EN55032, class A. They may cause radio interference in residential areas.
