INSTRUCTIONS
1) Description: DIN rail mountable primary switched-mode power supply with 187...265Vac - 250…345Vdc input, suitable for Single phase main line and DC line.
2) Installation: use DIN-rails according to EN 60715. 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 causes 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.
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 capacitors discharge.
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 <45°C) and 75°C (for ambient <
60°C).
Strip the connecting ends of the wires according to the indication on Fig.5 and ensure that all strands of a stranded wire enter the terminal connection.
4) Input protection : the device input is provided with varistors against overvoltage. Input isn’t provided with internal fuses, 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 according to local regulations.
5) AC input connection: the device can be connected to single-phase AC lines with Un 230 Vac (see Fig.7).
6) DC input connection: connect L terminal to + pole, N terminal to – pole and I terminal to GND. Rated voltage 250...345Vdc.
The device is also suitable for photovoltaic or wind turbine applications.
7) Output connection: The device is suitable for SELV and PELV circuitry.
Uout can be adjusted with a potentiometer (see Fig.1)
Check Uout before connecting the power supply to the load. With output voltage set to the max. value, the continuous current must not exceed the nominal power.
8) Parallel connection and redundancy: more 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.
For redundant connection, an external isolating device must be used.
1
9) Output protection: the device is protected against overload (OL) / short circuit (SC) / overvoltage (OV) / overtemperature (OT).
OL and SC: are controlled by an hiccup auto-reset protection with the following behaviour:
OL behaviour: Max. OL = In x 1.5 with constant output voltage for max. 5s. If the current is ≥ In x 1.5 the unit enters the OL protection and starts an ON/OFF cycle (hiccup).
SC behaviour: the device supplies the indicated short circuit peak current for 250 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 Uout  Unom x 1.2 – 1.3.
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.
When operating at normal load and > 45°C reduce the output power with 10W/°C.
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.
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) Warranty: power supplies are guaranteed free from factory defects for the time specified in the “Sales Conditions”
Failures caused by misuse, external and/or abnormal events (i.e. overvoltage, over temperatures) or non-respect of above parameters and standards, are not covered by warranty.
Opening the housing of the product makes warranty to be no longer valid.
In order to improve the products Nextys SA reserves the right to change product specifications, ratings and data without previous advice.
