Product Description
MEAN WELL QP-320D Switching Power Supply is a reliable and efficient 316W enclosed switch mode power supply featuring 4 DC outputs and a wide universal input voltage range from 90VAC to 264VAC (127VDC to 370VDC). Designed for industrial and electronic applications requiring stable and multiple output voltages, it supports outputs at 5V, 12V, 24V, and -12V with strong current capabilities.
This unit includes an integrated cooling fan to maintain thermal performance and ensures long-term stability with built-in overload, overvoltage, and over temperature protection. The adjustable output voltage on the first two outputs allows fine voltage tuning within a -5% to +10% range to meet sensitive equipment demands.
Additional features include power good and fail signal outputs for system monitoring and remote sense terminals to compensate for voltage drops in wiring. Installation is simplified with screw terminal connectors in a compact chassis mount format measuring 215mm length by 115mm width and 50mm depth.
The QP-320D operates safely across a temperature range from -10°C to 70°C and meets multiple international standards and approvals including AS/NZS62368.1, UL 62368-1, and others. Its high 83% efficiency rating improves electrical performance by minimizing wasted energy.
Four independent output channels provide versatile power configurations. Fan-cooled chassis mounting supports durable industrial use. Wide input voltage range with DC input compatibility ensures flexible deployment. Overload and fault protections safeguard connected systems.
Power status signaling outputs enable real-time monitoring. Compact size maximizes space savings in control panels. Certified to international safety and EMC standards. This Switching Power Supply is ideal for use in automation, electronic testing, instrumentation, machinery control, and telecommunications equipment.
