SDN-C Specifications (Three Phase)
1. SDN20 will operate at 75% load and SDN40 will operate at 50% load under loss of
1 phase. Units will shut down if thermal threshold is exceeded under this condition.
2. Unit passed input voltage overstress test at 600 Vac maximum without failure.
3. DC operation will require the user to provide the proper input circuit protection.
4. Input current ratings are specied with low input, line conditions, worst case
efciency values and power factor spikes. Input current at nominal input settings will
be typically half these values.
5. Losses are heat dissipation in watts at full load, nominal line.
6. Ripple/noise is stated as typical values when measured with a 20 MHZ, bandwidth
scope and 50 Ohm resister.
7. SDN 20 and SDN 40 unit will go to HICCUP mode. SDN 5 and SDN 10 will maintain
min 4 secs to deliver 150% load then drops to almost zero V out. The output voltage
will immediately drop to almost zero when load rises above 150%.

SDN-C Series Mounting (cont.)
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
Alternative Panel Mount: Using the optional SDN-PMBRK2
accessory, the unit can be screw mounted to a panel.
Chassis Mounting
Instead of snapping a Sola SDN™ unit on the DIN Rail,
you can also attach it using the screw mounting set
SDN-PMBRK2.
This set consists of two metal brackets, which replace the
existing two aluminum proles.
