Setting voltage (typ.) with open R-input
For derating at low input voltage see section Output Power Derating .
For minimum quantity and lead times consult Power-One.
The converters have been tested up to 440 Hz; for operating frequency <47 Hz or >63 Hz contact Power-One.
Nominal output figures, calculated with a cell voltage of 2.27 V at 20 °C.
Improved EMC performance. Former models without E are still available on request.
V i ≤ 250 VDC for models with option F.
Min. efficiency at V i nom , V o nom , I o nom , and T A = 25 °C. Typical values are approx. 2% better.
