Frequently Asked Questions
What loads is the RSP-100-27 intended for at 27V?
The RSP-100-27 delivers 27V at 3.8A (102.6W) and is suited for loads requiring a 27V DC bus, such as industrial pneumatic valve drivers, 24V lead-acid battery float chargers that need a slightly elevated supply, and certain specialty telecommunications equipment. The 85–264VAC input provides broad AC compatibility.
How does the RSP-100-27 compare to the RSP-100-24 and RSP-100-48?
The RSP-100-24 outputs 24V at 4.2A (100.8W), the RSP-100-27 outputs 27V at 3.8A (102.6W), and the RSP-100-48 outputs 48V at 2.1A (100.8W). All three use the same chassis (179.0 × 99.0 × 30.0 mm) and 85–264VAC input. The RSP-100-27 is the midpoint between 24V and 48V in this series.
Can the RSP-100-27 be used in telecom or datacom cabinets?
The RSP-100-27 is rated for -30°C to +70°C operation and holds BSMI, CB, CCC, CE, EAC, TÜV, and UL certifications. Its 27V output and compact 1U form factor make it compatible with telecom auxiliary circuits and datacom control boards that require a regulated 27V rail. The 3.8A output limits total load to 102.6W.
Is the RSP-100-27 rated for cold-climate operation?
Yes. The operating temperature floor of -30°C allows the RSP-100-27 to start and run in sub-zero ambient conditions. This makes it appropriate for outdoor enclosures in cold climates when housed in a sealed, weatherproof cabinet. No IP ingress rating is specified for the unit itself.
What are all voltage options available in the RSP-100 family?
The RSP-100 series offers output voltages from 3.3V to 48V across a single 1U platform: RSP-100-3.3 (66W/3.3V/20A), RSP-100-5 (100W/5V/20A), RSP-100-7.5 (101.25W/7.5V/13.5A), RSP-100-12 (102W/12V/8.5A), RSP-100-13.5 (101.25W/13.5V/7.5A), RSP-100-15 (100.5W/15V/6.7A), RSP-100-24 (100.8W/24V/4.2A), RSP-100-27 (102.6W/27V/3.8A), RSP-100-48 (100.8W/48V/2.1A). All models accept 85–264VAC input and share the 179.0 × 99.0 × 30.0 mm chassis.
