RB
Description
The RB series DC/DC converter has been designed for isolating or converting DC power rails in
general purpose applications. Although low cost, it does not compromise on features and offers
1KVDC/1s or 2kVDC/1s isolation, a –40°C to +85°C operating temperature range and optional
continuous short circuit protection.

Model Numbering
Notes:
Note3: standard part is without Continuous Short Circuit Protection
add suffix „/P“ for Continuous Short Circuit Protection
Note4: standard part is with 1kVDC/1s Isolation
add suffix „/H“ for 2kVDC/1s Isolation
or add suffix „/HP“ for 2kVDC/1s Isolation and Continuous Short Circuit Protection
Ordering Examples:
RB-123.3/P: 12VDC Input Voltage, 3.3VDC Output Voltage, Single Output with continuous short circuit protection and 1kVDC/1s isolation
RB-0509D/HP: 5VDC Input Voltage, ±9VDC Output Voltage, Dual Output with continuous short circuit protection and 2kVDC/1s isolation

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
