Frequently Asked Questions
What is the Mean Well LAD-240C designed for?
The Mean Well LAD-240C is a 240W security and fire alarm power supply with a built-in battery charger and UPS function. It is intended for systems that need regulated 41.5V output along with battery-backed power support and status monitoring.
What are the main electrical specifications of the LAD-240C?
This model is rated for 240W output with a 41.5V output voltage and 4.78A rated current. Its AC input range is 90 to 132VAC or 180 to 264VAC by switch, with a default setting at 230VAC, and it also supports 240 to 370VDC input.
Does the LAD-240C support battery backup functions?
Yes, the LAD-240C includes a built-in battery charger and UPS function for backup operation. It is suitable for both lead acid and lithium-ion batteries, and it also includes a forced UPS mode for battery maintenance.
What status signals and protections are available on the LAD-240C?
The unit provides TTL status signals for AC OK, battery disconnect, battery reverse polarity, battery low, battery full, and discharge. It also includes protection against short circuit, overload, over voltage, over temperature, battery low voltage, and battery reverse polarity without damage.
Can the LAD-240C be used in demanding temperature conditions?
The LAD-240C is specified for operation from -20°C to +60°C. That wide operating range makes it suitable for environments where power equipment may be exposed to both low and elevated ambient temperatures.
What certifications and standards does the LAD-240C meet?
This model is approved to UL62368-1, BS EN/EN62368-1, AS/NZS62368.1, and EAC TP TC 004 safety standards. Its design also refers to GB 17945-2010, and it meets EMC standards including EN55032 Class B and multiple EN61000 series requirements.
What makes the LAD-240C a good choice where space is limited?
The LAD-240C has a 1U low-profile design with a height of 30mm. Its compact 215 x 115 x 30mm form factor helps it fit into space-constrained equipment layouts while still delivering 240W output.
