2 Both outputs connected in parallel
3 Both outputs connected in series
4 For customer-specific models with 220 mm case length
5 Controlled by the battery temperature sensor, see Accessories
Various options are available to adapt the converters to
individual applications. An external temperature sensor is
available
to
allow
for
temperature
adapted
battery
charging.
The converters may either be plugged into 19" rack
systems according to IEC 60297-3, or be mounted on a
chassis or plate.
Important:
These products are intended to replace the LK1000 and
LK2000 models, in order to comply with IEC/EN 61000-3-2.
For applications with DC input or main frequencies other than
50/60 Hz, the LK1000 and LK2000 models are still available.
