Convectional cooling.
-Overvoltage protection, option A.The output
voltage is limited to 15% nominal output voltage.
A thyristor short-circuits the output.
-Undervoltage alarm with relay, option B The
logic alarm output is replaced with a relay with
selectable alarm logic NO or NC.
-Built in series diode, option C. A series diode
on the output, when output is connected in
parallel with other power supplies to achieve
redundancy. Output power is derated by 20%.
-Remote sense, option S. The voltage sensing
can be put at the load to compensate for voltage
drop.
-Inrush current limit with NTC, option H Only for
C -input code. Reduce the inrush current during the
start up. The input voltage range will be affected.
- 2.5kVac isolation input/case, option E1. On 24,
36 & 48V inputs The emission level increase to level A.
- 2.5kVac isolation output/case, option E2.
The emission level will increase to level A.
-Train input, option T. Input voltage range
according to train Standard EN50155 and IEC
60751.
- Euro panel, option L 8TE for PSE 150 & PSE
200, 10TE for PSE 250.
- Wall mounting panels, option N. Wall
mounting panel with connector holder The female
connector has to be chosen.
- H15 screw type female, H15-S
- H15 fast-on 6.3mm female, H15-T
- Din rail TS35 clips, option Q.
