Description
The RD series have been specifically designed for applications where dual power rails need to
be created from a single rail supply and a low cost solution is required. With efficiencies up to 87%,
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 industry standard input voltage and output voltage options plus an input to output isolation of 1kVDC
or 2kVDC makes these converters suitable for many industrial applications.

Model Numbering
Notes:
Note3: standard part is without Continuous Short Circuit Protection
add suffix „/P“ for Continuous Short Circuit Protection
Note4: add suffix „/H“ for 2kVDC Isolation
or add suffix „/HP“ for Continuous Short Circuit Protection and 2kVDC Isolation
Ordering Examples:
RD-123.3D/P: 12V Input Voltage, ±3.3V Output Voltage, Dual Output with continuous short circuit protection
RD-0509D/HP: 5V Input Voltage, ±9V Output Voltage, Dual Output with 2kVDC Isolation and continuous short circuit protection

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
