Converters

Description

• 1kVDC/1 second basic isolation

• Optional continuous short circuit protection

• UL94 V-0 package material

• No heatsink required

• Efficiency up to 85%

DC/DC Converter

The RI series has been specifically designed for applications where board space is at a premium since

these 2 Watt converters have only a slightly larger foot print than the RO series 1 Watt converters. With

efficiencies up to 85%, the full output power is available over the operating temperature range -40°C to

+85°C and the converters can be used in ambient temperatures of up to 100°C with derating. The wide

selection of input voltage and output voltage options plus an I/O-Isolation of 1kVDC as standard makes

these converters suitable for many industrial applications.

Notes:

Note1: Efficiency is tested at nominal input and full load at +25°C ambient

Note2: Max Cap Load is tested at nominal input and full resistive load and is defined as the

capacitive load that will allow start up in under 1s without damage to the converter
