MEAN WELL Security & Special Power Supply FAQs
Use these selection FAQs to compare product families by installation type, backup function, communication capability, application and operating environment.
DRC is positioned as a compact DIN rail security power supply family with integrated battery charging and backup functions across lower power levels. DRS extends the concept to higher power levels and adds more advanced monitoring and communication capabilities for applications such as fire alarm, emergency communication and intelligent DC backup systems.
The DRS and LAD Series are the strongest options in this category for fire alarm and emergency-system applications. DRC can also be suitable for lower-power backup requirements. Final selection should be based on required power, battery system, monitoring signals, communication functions and applicable system standards.
DRC, DRS, PSC and LAD include battery charging and backup or UPS functionality. SCP supports connection to an external battery but does not provide the same integrated battery charging control architecture. HEP is primarily a rugged industrial power supply family rather than a dedicated battery-backup family.
DRC and DRS are the main DIN rail families in this category. DRC covers lower power levels, while DRS is intended for higher-power systems requiring more advanced monitoring and communication functions.
PSC is a compact PCB or enclosed security power supply family suited to embedded and space-constrained systems. LAD uses an enclosed format and extends to higher output power, with security, fire alarm, backup and monitoring functions across 120W to 600W.
HEP is the main family for harsh-environment applications. It is designed for industrial and outdoor systems where dust, moisture, vibration, temperature variation or other demanding operating conditions must be considered.
DRS provides the most advanced monitoring and communication capability in this group, including MODBus and optional CANBus on supported models. LAD also provides status monitoring, with UART available on selected higher-power versions. DRC, PSC and SCP provide more basic status or detection functions depending on the model.
Start with the DC voltage required by the load and the battery system. Then verify load current, charging requirements, backup time, mounting format, monitoring functions and system standards. Not every product family supports every voltage, so final selection should be made from the exact model specifications.
