1. Product Overview:

️· RU/RUM Series: These are isolated DC/DC converters with two independent outputs.
️· Key Features:
- Isolated outputs (1kVDC input/output, output/output). "/H" versions offer 2kVDC isolation.
- Compact size (especially the RUM series).
- Wide input voltage range.
- Suitable for applications requiring multiple isolated channels.
️· Typical Applications: Multiple channel circuits where inter-channel isolation is needed.

2. Key Specifications:

️· Input Voltage: Varies by model (see selection guide).
️· Output Voltage: 5V and 3.3V models are shown in the example selection guide.
️· Output Current: 100mA per output.
️· Efficiency: Typically around 70-78%
️· Isolation Voltage: 1kVDC or 2kVDC (with the "/H" suffix)
️· Operating Temperature: -40°C to +85°C (with derating)

3. Models & Selection Guide:
