Frequently Asked Questions
Can I use the RDDW20H-12 for ±12V analog stages in industrial automation equipment?
Yes. It provides dual ±12V constant-voltage output with 20W total power, which fits low-power analog stages such as signal conditioning, instrumentation, and control-card support rails. Its -40°C to +85°C operating range also aligns with industrial temperature requirements.
Is the RDDW20H-12 suitable for embedded control boards that need split ±12V power?
It is intended for designs that specifically need dual ±12V rails rather than a single-output supply. The 20W rating and 50.8 × 25.4 × 10.2 mm size make it practical for compact embedded hardware where board space is limited.
Can this model be used for PLC or machine-control analog interface sections?
Yes, for low-power analog interface sections designed around ±12V constant-voltage input. The 20W output is appropriate for control electronics and interface circuitry, not for higher-power loads.
Is the RDDW20H-12 appropriate for harsh indoor environments with vibration?
The product features include 5G vibration resistance, and the operating temperature range is -40°C to +85°C. That supports use in industrial equipment installed in protected indoor enclosures where vibration and temperature variation are expected.
What is the difference between the RDDW20H-12 and RDDW20H-15?
Both are 20W converters in the same series with 43-160VAC input. The RDDW20H-12 provides 12V output at 1.83A, while the RDDW20H-15 provides 15V output at 667A. The main selection point is the output voltage requirement.
