For operating frequencies <47 Hz and >63 Hz contact Power-One. The converters have been tested up to 440 Hz.
Output power derating at low input voltage and/or high case temperature T C (see Output power derating ).
Models with feature E (type test with LWN1801-6E)
V i ≤ 250 VDC for models with option F.
Models with 12 V output: ≥ 0.70 for LWR, ≥ 0.75 for LWN
