INSTRUCTIONS
1) Description:
DIN rail mountable primary switched-mode power supply with 90...265Vac - 110…345Vdc input, suitable for Single phase main line and DC line.
Functions:
Power supply:
the units can be used as standard power supplies with 12-15V/7A (-12 Version) and 24V/5A (-24 Version) output rating.
Battery charger:
charging current regulator limits the charging current to 0.8A, thus avoiding higher charging currents dangerous for the battery life.
DC UPS function:
in case of the power supply incapacity of supplying the load (mains failure or unit failure) the load will continue to receive power from the battery without ANY
interruption, until the mains recovers or the battery reaches the “Deep Discharge Voltage” threshold ( 9.5V for -12 Version and 19V for -24 Version).
Deep discharge protection:
disconnects the battery from the load when its voltage is lower than 9.5V (-12 Version) or 19V (-24 Version).
The higher the charging current the higher the temperature of the battery, therefore the battery life increases if deep discharge is avoided (the battery life depends also by the numbers
of the charge/discharge cycles, their durations and by other various factors).
Battery reverse polarity protection:
in case of reverse connection of the battery the resettable fuse will trip and protect all circuitry.
Auto-resetting short circuit
protection:
connected in series to the line fed by the battery (the power supply output is actively protected against short circuit and overload)
Status signals:
a
green LED
, a
red LED
and a
dry SPST
contact displays the working status of the product, indicating “Load on Power Supply “ or “Load on Battery”
.
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.
5) AC input connection:
the device can be connected to single-phase AC lines with Un 120…240 Vac (see Fig.7).
6) DC input connection:
connect L terminal to + pole, N terminal to – pole and
I
terminal to GND. Rated voltage 110...345Vdc.
The device is also suitable for photovoltaic or wind turbine applications.
