SDN Series Power Supply (Single and Three Phase Units, 60-960 Watts)
The SDN DIN Rail power supply products provide industry leading performance. Sag immunity, transient suppression and noise tolerant, the SDN series ensures compatibility in demanding applications. Power factor correction to meet European directive, hazardous location approvals and optional redundant accessories allow the SDN series to be used in a wide variety of applications. Wide operation temperature range, high tolerance to shock and vibration and reliable design make the SDN series the definition of DC power quality.

Installation

 Fusing
   -Input

 Internally fused. External 10 A slow acting fusing for the input is recommended for SDN2.5, 4 5 and 10P models. A 16A slow acting fuse or time-delay circuit breaker is recommended for the SDN20 model.
   -Output

Outputs are capable of providing high currents for short periods of time for inductive load startup or switching. Fusing may be required for wire/loads if 2x Nominal O/P current rating cannot be tolerated. Continuous current overload allows for reliable fuse tripping.

 Mounting

 Simple snap-on system for DIN Rail TS35/7.5 or TS35/15 or chassis-mounted (optional screw mounting set SDN-PMBRK2 required).
 Connections  Input: IP20-rated screw terminals, connector size range: 16-10 AWG (1.5-6 mm2) for solid conductors. 16-12 AWG (0.5-4 mm2) for stranded conductors. 
 Output: Two connectors per output, connector size range: 16-10 AWG (1.5-6 mm2) for solid conductors.

SDN Series Mounting Top

DIN Rail Mounting

Snap on the DIN Rail:

1. Tilt unit slightly backwards.

2. Put it onto the DIN Rail.

3. Push downwards until stopped.

4. Push at the lower front edge to lock.

5. Shake the unit slightly to ensure
    that the retainer has locked.

SDNMount.JPG (24768 bytes)


Alternative Screwing-on:

  • Using the optional SDN-PMBRK2 accessory, the unit can also be screwed onto plane surfaces 
    (without DIN Rail).
Detachment from DIN Rail:

 Press button downwards (to unlock) and remove the
 unit from the DIN Rail.

 

Chassis Mounting Top

Instead of snapping a Sola SDN power supply unit on the DIN Rail, you can also attached it using the screw mounting set SDN-PMBRK2. This set consists of two metal brackets which replace the existing two aluminum profiles.

Note:

You need one SDN-PMBRK2 per unit.
In addition, two screws are required per SDN-PMBRK2 (e.g. M5 x 12), which are not included with the set.

Dimensions Top

 

 

Exchanging the Profiles Top
At the unit:
  • Remove the screw from the profile.
  • Pull the profile outwards to remove.

  • Push the SDN-PMBRK2 profile into the
    groove as far as possible.
    Secure with screw.

Note the orientation: The profile fits into the groove only as shown here.
