Frequently asked questions

• Q: Can I adjust the output voltage above 48V? Yes, the RSP-1500-48 has a ±10% adjustment range (43.2‑52.8V) via the built‑in potentiometer.
• Q: What is the maximum operating temperature at full load? It delivers full 1536W up to +50°C, then derates linearly to 50% load at +70°C.
• Q: Does it support parallel operation for higher power? Yes, the RSP-1500-48 includes active current sharing, allowing up to 3 units plus one redundant for 6000W total.
• Q: Is the fan always on? How noisy is it? The built‑in fan speed varies with internal temperature and load – at low loads it runs quietly.
• Q: What are the input voltage limits? It accepts 90‑264 Vac (47‑63 Hz) or 127‑370 Vdc, making it suitable for global use.
