Frequently Asked Questions
Can the RPS-400-27-SF be used for a higher-power 27V embedded computing or control platform?
Yes, if the platform needs constant 27V DC and the total draw remains within 9.3A. With 251.1W available, it suits 27V embedded or control assemblies that need more capacity than smaller 27V models in the same family.
Is this model appropriate for industrial instrumentation running from a 27V DC bus?
It is appropriate when the instrumentation requires a fixed 27V output and stays within 251.1W and 9.3A. The 80-264VAC input range also makes it easier to use in systems exposed to different AC source standards.
Can I use the RPS-400-27-SF for medical equipment that needs a stable 27V supply?
Yes, for equipment that needs constant 27V DC and does not exceed 9.3A. The specifications list medical safety approval and extreme low leakage current, which are relevant for medical-device power design.
Is the RPS-400-27-SF suitable for outdoor cabinets or unsealed equipment bays?
Its operating temperature range is -30°C to +70°C, so the temperature envelope is wide. However, no IP rating is listed, so the specs do not support treating it as an outdoor- or weather-exposed power supply.
Does the larger size of the RPS-400-27-SF matter when checking fit in a chassis?
Yes, because this version measures 160.0 x 86.0 x 43.0 mm and weighs 0.64 kg. That makes mechanical fit a separate check from electrical fit, even though the output remains 27V, 9.3A, and 251.1W.
