Frequently Asked Questions
What 48V applications can the RSP-100-48 support?
The RSP-100-48 delivers 48V at 2.1A (100.8W) and is appropriate for low-power 48V DC bus applications such as PoE switch auxiliary rails, industrial Ethernet backbone power, motor drive logic supplies, and distributed 48V bus segments in automation cabinets. The 85–264VAC input makes it compatible with all standard AC supplies.
How does the RSP-100-48 compare to the RSP-100-24 and RSP-100-27?
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 share the same 179.0 × 99.0 × 30.0 mm chassis, 85–264VAC input, and -30°C to +70°C operating range. Higher voltage variants deliver proportionally lower current at similar wattage.
Is the RSP-100-48 appropriate for telecom equipment requiring a 48V supply?
Yes. 48V DC is a standard bus in telecom infrastructure. At 100.8W the RSP-100-48 is suited for low-draw 48V telecom accessories, optical network unit (ONU) power, and small PBX systems. For loads exceeding 2.1A, the RSP-150-48 (3.2A) or RSP-200-48 (4.2A) should be considered.
What is the enclosure requirement for the RSP-100-48 in a dusty industrial environment?
The RSP-100-48 carries no IP ingress rating, so it must be mounted inside a sealed or filtered enclosure when used in dusty or wet industrial environments. It is rated for -30°C to +70°C operation and can handle the temperature demands of most factory installations when properly enclosed.
What are all RSP-100 series voltage options?
The RSP-100 series covers the following voltage options: 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 variants use the same 1U, 179.0 × 99.0 × 30.0 mm chassis and 85–264VAC input.
