FAQ
Can I use the RDDW10H-05 for embedded electronics that need dual 5V rails?
It is suited to embedded electronics that require a dual ±5V output and stay within the converter's 10W rating. This model provides constant-voltage output from a 43-160VDC input range. Its 31.8 × 20.3 × 12.7 mm size also supports compact embedded hardware.
Is the RDDW10H-05 a fit for industrial control boards with high-voltage input availability?
Yes, it is intended for applications operating from a 43-160VDC input span while delivering ±5V output. That makes it relevant for industrial control boards and support electronics built around higher-voltage input conditions. The unit is rated at 10W and uses constant-voltage operation.
Can this converter power low-voltage logic or interface circuitry in automation equipment?
It can fit automation subsystems that need regulated ±5V rails and remain within the 10W output rating. The listed dual-output feature is useful where split low-voltage rails are required. Its light weight of 0.016 kg also helps in dense or modular assemblies.
How does the RDDW10H-05 compare with the other RDDW10H models?
The listed RDDW10H models are all 10W converters with different outputs. The RDDW10H-05 is ±5V with ±1000mA output current, the RDDW10H-12 is ±12V with ±416mA output current, and the RDDW10H-15 is ±15V with ±333mA output current. This model's dimensions are 31.8 × 20.3 × 12.7 mm and its weight is 16g.
