PULS SL20.303 DIN-rail Power supply

Inrush current limiting done with a fixed 47R resistor (not a thermistor) which is bridged after the unit is running, so losses are minimised. That means no reset time even at a warm-start.

To be fused with a 3 x 10A, B-type 'circuit-breaker' switch based on the usual thermomagnetic overload sensing principle (used anyway to fuse the input lines; unit has no internal fuses).

To achieve current sharing the output V/I characteristic can be altered to be 'softer' (48.8 V at 0.1 A, 48 V at 10 A). This is done by repositioning a bridge connection (without opening the unit). 

Design advantages:

  • All connection blocks are easy to reach as mounted at the front panel.
  • PVC insulated cable can be used for all connections, as the connection blocks are mounted in the cooler area on the underside of the unit.

You can place an order for the PULS SL20.303 DIN-rail Power supply online via one of our Middle East branches (Dubai/ Oman/Saudi Arabia) and get it delivered at a low cost at a specific time.
