The Qualtek QPSF-125-5 is an open-frame AC/DC power supply designed for ITE (Commercial) applications. It delivers a 125W output with a single 5V, 20A channel.
This converter supports a wide universal input voltage range of 90-264 VAC and includes a built-in active Power Factor Correction (PFC) function, achieving a power factor greater than 0.95. It operates with an efficiency of up to 87% and features protections for Over Load (OLP), Over Voltage (OVP), and Short Circuit (SCP).
Designed for chassis mounting, the QPSF-125-5 has dimensions of 127.0mm x 76.0mm x 30.5mm. It operates within a wide ambient temperature range of -20°C to 70°C. Key features include adjustable output, remote sense functionality, and compliance with safety standards such as UL60950-1 and EN60950-1.
All internal components utilize 105°C long-life electrolytic capacitors, and the unit undergoes a 100% full load burn-in test to ensure reliability. The MTBF is rated at over 100,000 hours at 25°C and full load.
The output voltage is 5V with a rated current of 20A, providing 125W of power.
The universal input range is 90-264VAC (47-63Hz) or 127-370VDC.
Yes, it has built-in active PFC with typical power factor >0.98 at 115VAC and >0.95 at 230VAC.
Over load protection (hiccup mode, auto recover), over voltage protection (hiccup mode), and short circuit protection (auto recovery).
The operating temperature range is -20°C to 70°C with derating.
It is an open frame converter designed for chassis mount. Dimensions are 127.0mm x 76.0mm x 30.5mm.
