DC/DC Converter
RHV3
Description
The RHV3 is a DC/DC converter with exceptionally high 20kVDC (12.5KVAC/1 minute) isolation in a compact SIP16 case. Input voltages can be 5, 12 or 24VDC and outputs 5V, 12V, 24V, ±5V or ±12V. The operating temperature is -40°C to +80°C without derating. Applications include high vacuum monitoring, X-Ray equipment, HVAC dust extraction systems and other high voltage industrial applications where a very high isolation remote power supply is required.
