Frequently Asked Questions
What is the Mean Well LAD-360U designed for?
The LAD-360U is a 360W security and fire alarm power supply with a built-in battery charger and UPS function. It is intended for systems that need a regulated 27.6V DC output plus battery-backed operation during AC power loss.
What output does the LAD-360U provide?
This model provides a 27.6V DC output and is rated for 11.5A, with a total power rating of 360W. The CH1 output voltage is also adjustable by VR within the stated range of -2% to +5%.
Does the LAD-360U support battery backup operation?
Yes. The LAD-360U includes both a built-in battery charger and UPS function, making it suitable for backup-power applications in security and fire alarm systems. It also includes a forced UPS mode for battery maintenance.
What battery types is the LAD-360U compatible with?
Mean Well specifies that the LAD-360U is suitable for both lead acid and lithium-ion batteries. That makes it a flexible option for systems using different battery chemistries, provided the overall system design matches the product's electrical requirements.
What status monitoring signals are available on the LAD-360U?
The unit provides TTL status signals for AC OK, battery disconnect, battery reverse polarity, battery low, battery full, and discharge. These signals help support system-level status detection and monitoring in more advanced security or alarm applications.
What protection features are built into the LAD-360U?
The LAD-360U includes protection for short circuit, overload, over voltage, over temperature, battery low voltage, and battery reverse polarity. Mean Well also states that battery reverse polarity protection is no-damage.
Is the LAD-360U suitable for demanding operating environments?
It is rated for operation from -20°C to +60°C, which supports use in a wide range of commercial and industrial indoor environments. The unit also meets listed safety and EMC standards, including UL62368-1 and EN55032 Class B.
How compact is the LAD-360U for panel or enclosure use?
The LAD-360U uses a 1U low-profile design with a height of 30mm. Its stated dimensions are 215 x 115 x 30mm, which can help when space is limited in compact security or fire system enclosures.
