What applications require 27V DC that the RSP-500-27 can serve?

The RSP-500-27 provides 27V at 18.6A (502.2W), used to power certain motion control amplifiers, specialized 24-28V nominal equipment, and industrial bus systems. Its 1U form factor (230.0 × 127.0 × 40.5 mm) is compatible with standard rack enclosures.

What is the operating temperature range of the RSP-500-27?

The RSP-500-27 operates from -30°C to +70°C ambient. It is designed for indoor enclosed use and holds BSMI, CB, CCC, CE, EAC, c_rcm, TÜV, and UL certifications.

How does the RSP-500-27 compare to the RSP-500-24 and RSP-500-48?

All three use the same 230.0 × 127.0 × 40.5 mm chassis and 85-264VAC input. The RSP-500-24 provides 504W at 21A, the RSP-500-27 provides 502.2W at 18.6A, and the RSP-500-48 provides 504W at 10.5A. Power output is similar across the group; current decreases as voltage increases.

What does the RSP-500-27 weigh and what warranty is included?

The RSP-500-27 weighs 1.3 kg and includes a 3-year warranty. It incorporates built-in active PFC and accepts 85-264VAC universal input.
