Frequently Asked Questions
What is the Mean Well LAD-360D designed for?
The LAD-360D is a 360W AC-DC power supply built for security and fire alarm systems that need battery backup support. It combines a 55.2V main output with a built-in battery charger and UPS function, so it suits applications where power continuity and system status monitoring matter.
Does the LAD-360D support battery backup operation?
Yes. This model includes a built-in battery charger and UPS function, and it also supports a forced UPS mode for battery maintenance. It is specified as suitable for both lead acid and lithium-ion batteries.
What status signals are available on the LAD-360D?
The LAD-360D provides TTL signals for AC OK, battery disconnect, battery reverse polarity, battery low, battery full, and discharge status. These signals make it useful in systems where remote status detection or supervisory monitoring is required.
What are the main electrical ratings of the LAD-360D?
This model is rated for 360W output, with a nominal output voltage of 55.2V and rated current of 5.03A. The CH1 output voltage is adjustable by VR within approximately -2% to +5%, which can help match system requirements within the product's stated range.
Is the LAD-360D suitable for demanding operating environments?
It is designed for operation from -20 to +60 degrees C, which gives it a relatively wide working temperature range for indoor industrial and security system use. The unit also includes protections for short circuit, overload, over voltage, over temperature, battery low voltage, and battery reverse polarity with no damage.
How is the LAD-360D different from a standard AC-DC power supply?
Unlike a basic fixed-output power supply, the LAD-360D is built specifically for backup-power applications in security and fire alarm systems. Its differentiators are the integrated battery charger, UPS function, forced UPS maintenance mode, and TTL status outputs for system monitoring.
Is the LAD-360D a good fit where space is limited?
Yes. The unit uses a 1U low-profile design with a height of 30mm and overall dimensions of 215 x 115 x 30mm. That makes it better suited than larger chassis-style supplies for compact equipment layouts where backup capability is still required.
