The ARCH MQF500 500W AC-DC switching power supply is engineered for high-performance applications that demand efficiency, reliability, and integration flexibility. With up to 93% efficiency and a P.F.C. function > 0.94, the switching power supply significantly outperforms competing models, offering enhanced thermal performance and energy savings. MQF500 switching power supply delivers a strong balance of power efficiency and application versatility.
Integrated Functions for Maximum Flexibility
The MQF500 includes a suite of built-in features designed to enhance system versatility and simplify integration:
● 5V@1A standby output — Supports smart monitoring, wake-up functions, and low-power peripherals offering greater flexibility and control for modern embedded designs.
● Remote ON/OFF control (RC function) — Enables intelligent power management and remote activation for system efficiency.
● Optional current share function — Allows parallel operation in high-power systems, enhancing scalability, redundancy, and making the MQF500 switching power supply ideal for applications requiring backup or failover capability.
Dual Certification for Industrial and ITE Applications
The MQF500 switching power supply is certified to both IEC/UL/EN 60601-1 (medical) and 62368-1 (ITE/industrial), making it a dual-certified solution ready for deployment across a wide range of industries. Supporting both Class I and Class II installations, the switching power supply eliminates the need for multiple SKUs in different grounding configurations—saving development time, certification effort, and cost.
Superior Safety, EMC Compliance, and Ultra-Low Leakage Current
Designed with patient and operator safety in mind, the MQF500 switching power supply offers:
● 4000VAC input-to-output isolation
● 2xMOPP protection
● Touch leakage current < 0.1mA, far superior to typical levels seen in competing models, minimizing risk in sensitive environments. This makes it exceptionally well-suited for critical systems in both medical and industrial fields.
● Full EMC compliance without requiring external components, ensuring reliable operation while simplifying system integration and reducing design complexity.
These features make the MQF500 switching power supply exceptionally well-suited for critical medical and industrial systems, where safety, compliance, and performance must all work in harmony.
Proven Durability with Shock and Vibration Resistance
Beyond standard electrical safety, the MQF500 switching power supply is tested to IEC 60068 shock and vibration standards. Combined with an MTBF > 160,000 hours (MIL-HDBK-217F), the switching power supply ensures long-term system reliability in high-demand or mobile deployments.
Trusted Performance in Critical Applications
With its wide operating temperature range (-30°C to +70°C), universal 90–264 VAC input, and compact form factor, the MQF500 switching power supply is already trusted in applications such as patient monitors, X-ray systems, CT scanners, laser equipment, and advanced industrial devices. Its mix of power, protection, and versatility makes it a future-ready power platform.
