Frequently Asked Questions
Can the RPS-400-18-SF be used for an 18V medical analyzer or diagnostic system?
Yes, if the equipment requires 18V constant-voltage power and draws no more than 13.9A or 250.2W. Its medical approval and low leakage current are aligned with medical and laboratory equipment categories.
Is this power supply suitable for 18V automation subsystems in a control enclosure?
It can support 18V automation subsystems, control electronics, or industrial instrumentation that need a stable 18V rail. The main sizing limits are 13.9A output current and 250.2W total output power.
Can I use the RPS-400-18-SF for an 18V test bench or validation fixture?
Yes, for benches or fixtures designed around 18V DC, provided the full load remains within 250.2W. This type of supply is useful when a fixture combines several 18V loads and needs more than the lower-power RPS models provide.
Would the RPS-400-18-SF fit a larger 18V equipment chassis better than smaller open-frame versions?
This version measures 160.0 x 86.0 x 43.0 mm and weighs 0.64 kg, so it is the larger-format option among the 250.2W, 18V models listed here. It still delivers the same 18V and 13.9A output as the other RPS-400-18 variants.
Is the RPS-400-18-SF appropriate for outdoor use?
Its operating temperature range is -30C to +70C, but there is no IP rating shown in the supplied specs. In practice, that makes it a better fit for indoor equipment or sheltered enclosures rather than direct outdoor exposure.
