USER INSTRUCTIONS
1) Description: DIN rail mountable primary switched-mode power supply with 90...264Vac (110…345Vdc) input, 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 betterdevice stabilityfix the rail to the wallclose to the point where
the device is to be mounted. Inorder to guarantee sufficient convection, we recommend observing a minimumdistance to other modules (see Fig.3).
The device isprovided with a thermal protection; a limited air flow can cause the thermal protection tripping.
The SMPS automatically restartsafter cooling. Toget normal operation reduce thetemperature ofthe 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 capacitorsdischarge (minimum 1 minute)
In order to complywith UL certification, use appropriate copper cables of indicated crosssection, 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 wiresaccording 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 mustbe provided by the end user(see Fig.6).
For operation on a single-phase system, a protection fuse on the phase mustbe provided.
Surge protection: it isstrongly recommended to provide external surge arresters(SPD) according to local regulations.
5) AC input connection: the device can be connected to single-phase AC lineswith Uin 120…240Vac (see Fig.7). Please connectfirst the PE.
6) DC input connection: connect L terminal to (+)positive pole, N terminal to (-)negative pole and Iterminal to GND. Rated voltage 110...345Vdc.
The device isalso suitable for photovoltaicor wind turbine applications (see Fig.7).
7) Output connection: The device issuitable 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 [currentx voltage] must not exceed the nominal power.
8) Parallel connection and redundancy: power supplies can be connected in parallel to increase power. For paralleling for power set the Ilim jumper to C.C. algorithm.
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 mustbe used (see accessorydevice).
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 or a constant current (C.C.) mode protection with the following behaviour.
The Hiccup modeor C.C. mode are selectable with Jumper (see Fig.1)
OL behaviour in hiccup mode: Max. OL= 1.5 x In the output voltage remains constant at nominal voltage for 5s and after that time the device starts an ON/OFF cycle.
OL behaviour in C.C. mode: the maximum output current is limited at 1.5 x In ifthe load resistance is furtherdecreased the output voltage starts to drop.
SC behaviour in hiccup mode: the device supplies 1.5 x In for 5s, afterthat time it switches off for 10s. The ON/OFF cycle is repeated continuously.
SC behaviour in C.C. mode: the device supplies 1.5 xIn the outputvoltage dropsto a value depending on the impedance ofthe failed load circuit. After 5s the current is
limited to In. The device never switches off.
Output OV circuit protection: the outputis protectedagainst potential OVdue to internal malfunction or coming from the load for Uout Unom x 1.2 – 1.3, depending on the
model.
OT protection: turns offthe device if the internal temperature exceeds a safe limit.
The device restartsautomatically after cooling down. To recover to normal operation reduce airtemperature 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 whena motor starts-up under effortits consumption ismuch higher than thenominal current and it
can trigger overcurrent protection (see accessory device). For these applications the C.C. (Constant Current) mode of current limitation is recommended.
NOTE: motors can generate high conducted noiseon the DC line.Therefore it isnot recommended to feed on the same line motorsand equipment sensitive to noise.
11) Operation with Battery: when a battery is connected in parallel to the Output for backup purposes; the NPSM121 mustbe set on C.C. mode to avoid battery over-charging
(see accessory device).
