USER INSTRUCTIONS
1) DESCRIPTION
DIN rail mountable primary switched-mode power supply with 90 - 264 VAC or 110 - 345 VDC input (UL not evaluated), 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 fuses 3.15AT / 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). Ensure that the PE conductor is properly connected.
Please connect the PE first.
6) DC INPUT CONNECTION
Connect L terminal to (+) positive pole, N terminal to (-) negative pole and terminal to GND. Rated voltage 110 – 345 VDC (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.
Vout can be adjusted with a potentiometer to a wide range (see Fig.1). 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 (±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 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.
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 EN 50178).
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 designed according to EN 55032, class A. It may cause radio interference in residential areas.
