Originally developed by Astec International—a pioneer in power electronics later acquired by Artesyn Embedded Technologies—the AM80A-150L-065F33 is engineered for demanding industrial, test & measurement, and embedded control applications where compact size, efficiency, and long-term stability are critical. This unit operates from a universal AC input range of 85–264 VAC (or 120–370 VDC), enabling global deployment without manual voltage selection.

As part of Astec’s AM80A series, the AM80A-150L-065F33 features convection-cooled operation with no internal fan, ensuring silent, maintenance-free performance in sealed or dust-prone enclosures. It delivers tightly regulated output with low ripple and noise, making it suitable for powering sensitive analog circuits, programmable logic controllers (PLCs), human-machine interfaces (HMIs), and communication modules. The ASTEC AM80A-150L-065F33 incorporates comprehensive protection mechanisms—including overvoltage, overcurrent, short-circuit, and thermal shutdown—to safeguard both the power supply and downstream electronics during fault conditions. With certifications including UL, CSA, TÜV, and CE, this module meets stringent safety and EMC requirements for industrial and semi-medical use.

Technical Specifications

Main Features and Advantages

High-efficiency, fanless design for silent and reliable operation: The ASTEC AM80A-150L-065F33 leverages advanced switching topology to achieve over 82% efficiency at full load, minimizing heat generation and eliminating the need for a cooling fan. This not only ensures silent operation—critical in laboratory, medical, or office-adjacent industrial settings—but also removes a common point of mechanical failure, significantly enhancing long-term reliability in unattended systems.

Universal input for global deployment: With a wide input range of 85–264 VAC, the AM80A-150L-065F33 automatically adapts to any standard mains voltage worldwide, from 100 VAC in Japan to 240 VAC in Europe. This eliminates the need for external transformers or manual jumper settings, simplifying inventory management for OEMs shipping equipment internationally.

Robust protection suite for system resilience: The ASTEC AM80A-150L-065F33 includes auto-recovery overvoltage protection (OVP) that clamps the output if regulation fails, preventing damage to downstream circuitry. Short-circuit and overcurrent protection operate in constant-current mode, allowing the unit to safely ride through transient faults without latching off. Thermal shutdown activates only under extreme ambient or overload conditions, ensuring maximum uptime.

Compact open-frame format for embedded integration: Measuring just 5.0″ × 3.0″ × 1.5″, the AM80A-150L-065F33 fits easily into space-constrained control cabinets or OEM chassis. Its open-frame construction allows optimal airflow and thermal coupling to metal surfaces, further improving heat dissipation. Mounting holes align with standard patterns, facilitating rapid integration into custom enclosures.

Certified safety and low EMI for compliance assurance: The ASTEC AM80A-150L-065F33 complies with EN 55022 Class B radiated and conducted emissions limits, reducing the risk of electromagnetic interference with nearby sensors or communication devices. Combined with its full suite of safety agency approvals, this makes the module suitable not only for industrial automation but also for semi-medical or test equipment requiring rigorous regulatory compliance.

Application Field

The ASTEC AM80A-150L-065F33 is widely used as a primary or auxiliary power source in industrial automation, test instrumentation, and embedded computing systems. In factory automation, it powers PLC I/O modules, small servo drives, and operator panels where stable 15VDC is required for analog signal conditioning or relay excitation. Its low-noise output makes it especially suitable for precision motion control or data acquisition subsystems that are sensitive to power supply ripple.

In the test & measurement sector, the AM80A-150L-065F33 serves as the internal power converter in benchtop analyzers, environmental chambers, and semiconductor test handlers—applications that demand quiet operation and minimal electrical interference. Because it carries industrial safety certifications and offers high MTBF, it is also commonly found in telecom edge equipment, networked industrial gateways, and remote RTUs deployed in uncontrolled environments.

Medical OEMs occasionally specify the AM80A-150L-065F33 for non-patient-connected devices such as diagnostic imaging peripherals or lab automation tools, leveraging its EN 60601-1 collateral compliance (via IEC 60950-1). Across all applications, the ASTEC AM80A-150L-065F33 delivers a balance of power density, reliability, and regulatory readiness that reduces time-to-market and total cost of ownership for system integrators and equipment manufacturers alike.

Installation and Maintenance

Pre-installation preparation: Before installing the ASTEC AM80A-150L-065F33, ensure adequate clearance (minimum 10 mm on all sides) for natural convection cooling. Verify that the input AC wiring complies with local electrical codes and that the load does not exceed 5.33 A continuous. Use appropriately rated terminals and torque screws to 5.6–6.2 in-lb (0.63–0.7 Nm) to prevent arcing or thermal issues. Ground the mounting chassis to earth to meet EMC and safety requirements.

Maintenance recommendations: The ASTEC AM80A-150L-065F33 contains no user-serviceable components and requires no routine maintenance. However, periodically inspect for dust accumulation on the PCB surface in dirty environments, as excessive buildup can impede heat dissipation. If the unit fails to power up, check input fuse integrity and measure open-circuit output voltage; a shorted load may cause the supply to enter hiccup mode. Always disconnect AC power before handling. Due to its high MTBF, the AM80A-150L-065F33 typically operates for years without issue—keeping a spare ensures rapid recovery in mission-critical systems.
