## Long description

HiSmart DR-240-12 is a DIN-rail switching power supply that provides 12 V DC at up to 20 A (240 W). Designed for use in control cabinets and electrical installations, it delivers a stabilized low-voltage output with compact dimensions and convection cooling for continuous operation in applications such as access control, CCTV, LED lighting and other low-voltage equipment.
Advantages
The DR-240-12 uses pulse (switching) operation to achieve high efficiency (86%) while keeping size and weight low. It is intended for TS-35/7.5 or TS-35/15 DIN-rail mounting and features protections against short circuit, overload, overvoltage and overtemperature. Convection cooling removes the need for fans, reducing maintenance and noise.
Suitable for
Access control systems
CCTV and surveillance cameras
LED lighting installations
Control cabinets and automation equipment
Any 12 V DC devices requiring up to 20 A total

Adjust the DC output within the specified -9%/+10% range if needed, then connect the 12 V DC loads ensuring the total current draw does not exceed 20 A. Leave adequate space around the unit for convection cooling and observe the specified ambient temperature and humidity limits.
Usage recommendations
Install the unit in a dry, ventilated cabinet and use proper fusing on both the AC input and DC output. Verify total connected load and allow margin below the 20 A rating for reliable long-term operation. Do not obstruct airflow around the housing and avoid mounting near heat sources.
