To be fused with a 16A, B-type 'circuit-breaker' switch based on the usual thermomagnetic overload sensing principle (used anyway to fuse the
input lines).
EN 61000-3-2 (harmonic current emissions [PFC]) is fulfilled
Transient

Over-voltage protection

(at Tamb = 60-70°C)

At 49V ±10%: switch to hiccup mode

Front panel indicators:
• Green LED on, when Vout = Vout adjusted
• Red LED on, when Vout < Vout adjusted
Parallel operation

Yes, up to ten SL20

To achieve current sharing the output V/I characteristic can be altered to
be 'softer' (36.6V at 0A, 35.2V at 13.3A). This is done by repositioning an
external bridge connection (without opening the unit).

Design advantages:
• All connection blocks are easy to reach as mounted on 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.
