Both regulated and unregulated output models are available. The ISA, ISE, ISH and ISK series offer unregulated outputs while the ISR and ISW have regulated outputs. ISE and ISA ranges provide 1W output with single and dual unregulated outputs respectively, the ISH is a 2W version of the ISE range, and the ISK offers an unregulated 0.25W single output. ISW is a 1W single output converter with a regulated output, with the ISR range providing a regulated 3W single output. Accordingly there are various combinations of single output models from 3.3 to 24VDC, and dual output models with outputs of ±5, ±9, ±12, ±15 and ±24VDC. Each series offers up to five ±10% input voltage ranges or a 2:1 input range on the ISR series.

Offering standard 1.5 or optional 3 kVDC input / output isolation figures, the converters measure 12.7 x 8.3 x 7.25 mm for the ISE, ISH and ISK ranges. The ISA and ISW measure 15.24 x 8.30 x 7.25 mm and the ISR measures 23.86 x 13.70 x 8.00 mm. All have industry standard pin outs. The converters feature an extended operating temperature range of -40 to +105C for the ISA, ISE, ISH, ISK and ISR ranges (+85C for ISW), and full output power up to +100C is achievable (+85 C for ISR and +70C for ISW).

The ISA/E/H/K/R/W series is available from Farnell element14, Digi-Key.
