MPO-MS Series

The MPO-MS series, by MicroPower Direct, is an enclosed AC-DC switching power supply series designed for use with BF type medical equipment, which involves direct patient contact. This series has universal AC input capability and the ability to accept DC input voltages, making it a versatile and cost-effective choice for medical system applications. It boasts features such as low power consumption when idle, high efficiency, exceptional reliability, high electromagnetic compatibility (EMC) performance and double or reinforced insulation. 

Moreover, the MPO-MS series is equipped with an active Power Factor Correction (PFC) function and supports a wide input range of 85 – 264VAC/120 – 370VDC. Its operational temperature range of -40 to +85 ensures reliable performance in both indoor and outdoor environments with significant temperature variations, without the need for additional cooling or heating mechanisms at startup in cold conditions. The series meets standards such as IEC/EN/UL62368, IEC/EN60335, GB4943, IEC/EN/ES60601, and IEC/EN61558, and is adaptable for installation in systems classified as Class I (with PE) or Class II (without PE), making it an ideal choice for industrial settings as well as office and residential applications.

Common Features Across All Models

• UL Approvals: All models have UL approvals, ensuring safety and reliability in their designated applications.

• Compact Design: Despite the varying power outputs, each model is designed to maximize space efficiency, making them ideal for applications with limited space.

Active Power Factor Correction (PFC): Improves power efficiency and reduces electrical noise in the power system.

• Wide Operating Temperature Range: All models are capable of operating in a wide temperature range, making them versatile for different environmental conditions.

Applications

The primary and secondary sides of the MPO-MS series have reinforced insulation with 2*MOPP, and the isolation voltage is up to 4000VAC. The touch current is as small as 0.1mA, which is suitable for patient contact and patient assistance.

As an example, the MPO-MS series could be used in the operation of X-ray machines, particularly in medical imaging systems. X-ray machines require a stable and reliable power supply for various components to function optimally.

In addition, the MPO-MS series is ideal for non-medical industries. In the rail transportation industry, the need for reinforced insulation is a common requirement due to the harsh environments and safety standards. The MPO-MS series, with its 4000VAC isolation voltage, is an ideal solution, meeting the stringent insulation demands within this sector. Industrial environments are often characterized by their harsh conditions, including high levels of dust, vibration, and variable temperatures. The MPO-MS series is designed to withstand these conditions, ensuring reliable operation of machinery in any industrial setting.

Their compact sizes and low cost, combined with high power outputs and compliance with safety standards, make them versatile for a wide range of applications.
