Review MEAN WELL Mw Mini din Connector 48vdc 66w For Poe Switch/poe Injector

The Mean Well P66A-8MD03 MW is a compact and powerful 48V DC 66W Mini-DIN connector power supply unit (PSU) specifically designed for Point of Entry (PoE) switches and PoE injectors. This PSU delivers a constant and reliable power source to enable PoE functionality, allowing for the delivery of power and data over Ethernet cables.

Measuring just 90mm in length, 44mm in width, and 21mm in height, the Mean Well P66A-8MD03 MW is an ideal choice for applications where space is at a premium. Despite its small form factor, this PSU boasts an impressive efficiency of up to 90%, ensuring minimal power loss and optimal energy utilization.

The PSU features a universal input voltage range of 90-264V AC, making it suitable for use in various regions and power grid conditions. It also comes equipped with overvoltage, overcurrent, and short-circuit protection, ensuring the safety and longevity of connected devices.

The PoE PSU utilizes a Mini-DIN 4P 4C connector, which offers 8 pins for power input and 4 pins for power output. The power output pins are configured according to the IEEE 802.3af and IEEE 802.3at PoE standards, enabling the delivery of up to 30W of power per port for Type 1 devices and up to 60W for Type 2 devices.

The Mean Well P66A-8MD03 MW is designed to operate in temperatures ranging from -10 C to 40 C, ensuring stable performance in various environments. With its robust construction, compact size, and high efficiency, this PSU is an excellent choice for installations requiring PoE functionality, such as IP cameras, VoIP phones, and wireless access points.

The Seasonic SGX-660 66W 48V DC Power Supply Unit (PSU) with a mini-DIN connector (model: SGX-660-M12BN, formerly known as SGX-660-M12LD and SGX-660-M12LP, and sometimes referred to as the Mean Well LD-66 or P-S660-30M) is a popular choice for Power over Ethernet (PoE) applications, such as switches and injectors. Here are the pros and cons of buying this particular PSU:

1. High efficiency: The Seasonic SGX-660 PSU offers high efficiency, which means it converts a large portion of the input power into output power, reducing energy waste and heat generation.

2. Compact size: The mini-DIN connector and compact size make it an ideal choice for space-constrained installations, such as in telecommunications, industrial automation, and other industrial applications.

3. Reliable: Seasonic is a well-known and reputable brand in the power supply industry, known for producing high-quality and reliable products.

4. Low noise: The SGX-660 PSU operates quietly, making it a good choice for environments where noise levels need to be kept low.

5. Wide input voltage range: The PSU can accept a wide range of input voltages (90-264Vac, 190-450Vdc), making it suitable for use in various locations and applications.

1. Limited power output: With a maximum power output of only 66W, this PSU may not be suitable for high-power PoE applications, such as those requiring multiple PoE devices or high-power devices, such as IP cameras or Wi-Fi access points.

2. Limited compatibility: The mini-DIN connector and compact size may limit compatibility with certain PoE switches and injectors, so it's important to check the compatibility before making a purchase.

3. Cost: The SGX-660 PSU may be more expensive than some other options with similar power output and connector types.

In conclusion, the Seasonic SGX-660 66W 48V DC Power Supply Unit with a mini-DIN connector is a reliable, efficient, and compact power source for PoE applications where space and noise levels are concerns, but it may not be suitable for high-power applications or those with specific connector requirements. If you're looking for a more powerful or cost-effective option, you may want to consider other PSUs with different connector types or power outputs.

Based on the information provided, I would recommend the Seasonic SGX-660 PSU for PoE applications where a compact, efficient, and reliable power source is required, and where the power requirements are within the limits of the PSU. It's important to check the compatibility of the PSU with your specific PoE device before making a purchase.
