Frequently Asked Questions

What is the Mean Well AD-55B designed for?

The AD-55B is a security power supply intended for applications that need a regulated 27.6V DC output with UPS functionality. It is suited to security and enclosed power supply use cases where backup-related operation is part of the product requirement. This model is part of Mean Well's AD series and is rated at 53.92W.

What are the main output specifications of the AD-55B?

This model provides a 27.6V DC output at up to 1.8A. Its rated output power is 53.92W. Those specifications make it a fit for loads that require this voltage and current range.

Does the AD-55B support a wide AC input range?

Yes. The AD-55B accepts 88 to 264VAC, and it also supports 124 to 370VDC input. That wide input range helps when the same model needs to be used across different regional mains standards.

What protection features are included in the AD-55B?

The AD-55B includes short circuit, overload, and over-voltage protection. It also includes battery low protection, which is relevant to its UPS-oriented design. Overload protection is specified at 105% to 150% of rated output power, and over-voltage protection is 115% to 135% of rated output voltage.

What operating environment is the AD-55B rated for?

The AD-55B is specified for operation from -10°C to +60°C. Cooling is by free air convection, so it is designed for passive cooling rather than forced-air operation. Buyers should confirm the surrounding enclosure and ambient conditions stay within the product's rated temperature range.

What certifications and compliance standards does the AD-55B meet?

This model is approved to UL62368-1, TUV BS EN/EN62368-1, AS/NZS 62368.1, and EAC TP TC 004 safety standards. Its EMC compliance includes EN55032 Class B, EN61000-3-2, EN61000-3-3, and multiple EN61000-4 immunity standards. These approvals can matter for commercial and professional security power supply projects.
