FAQ

Can I use the RDDW20F-15 for ±15V signal-conditioning or analog control circuits in industrial equipment?

Yes, if your design needs a constant ±15V output from a 9-36VDC source, this model is aligned with that requirement. Its 20W rating suits lower-power industrial, IT, or embedded analog sections rather than large system loads.

Is the RDDW20F-15 suitable for embedded test, measurement, or amplifier stages that require dual 15V rails?

It can be used where the electronics need a regulated ±15V constant-voltage supply and the total demand remains within 20W. The compact 50.8 × 25.4 × 10.2 mm size also helps in dense equipment layouts.

Can this converter work in vehicle-adjacent or machine-mounted control electronics with a 9-36VAC source?

The 9-36VDC input range makes it relevant for systems built around lower-voltage industrial or mobile power ranges. Its 2G vibration feature and -40°C to +85°C operating range also support use in tougher embedded or automation environments when ±15V is required.

Does the RDDW20F-15 support outdoor environments?

The converter is specified for operation from -40°C to +85°C, so the temperature range is broad. Since no IP rating is listed, the provided specs support use in protected indoor enclosures more clearly than direct outdoor exposure.

How does RDDW20F-15 compare to RDDW20F-05 and RDDW20F-12?

The three RDDW20F versions all share 20W output power, 9-36VDC input, constant-voltage operation, 50.8 × 25.4 × 10.2 mm dimensions, 35g weight, and a -40°C to +85°C temperature rating. The output options are ±5V at 2A for RDDW20F-05, ±12V at 835mA for RDDW20F-12, and ±15V at 666mA for RDDW20F-15.
