FAQ
Can I use the ERP-350-24 for a 24V industrial automation or control application?
Yes, if the equipment requires 24V constant voltage and does not exceed 14.6A or 350W. That makes it suitable for many 24V industrial and automation loads powered from 180-264VAC input.
Is the ERP-350-24 suitable for 24V PLC-related devices, sensors, or cabinet electronics?
It can be used for 24V constant voltage cabinet electronics that fit within its 14.6A and 350W output limits. The unit is an AC-DC power supply with overload, over-voltage and over-temperature protection, which can be useful in industrial cabinets.
Can this power supply run 24V embedded or industrial computing hardware?
Yes, for 24V constant voltage hardware whose total draw stays within 350W and 14.6A. Its 180-264VAC input range matches standard AC-powered industrial equipment environments.
Is the ERP-350-24 a reasonable option for 24V systems that need a 350W supply?
Yes. This model is rated for 24V output at up to 14.6A, with a total power rating of 350.4W. Its size is 220.4 × 130 × 48 mm.
Can the ERP-350-24 be used in outdoor or semi-exposed locations?
The datasheet states that the ERP-350 is designed for outdoor application but should be installed in a sheltered place, and its operating temperature range is -30°C to +60°C with output load derating. However, no IP rating is listed, so the specs do not define a formal ingress-protection level.
