Designed for industrial use, the unit resists vibrations up to 5G. It performs well in both low and high-temperature environments, making it a durable option for long-term use.
The LRS 35 12 reaches a peak efficiency of 89%. This reduces heat buildup and power loss, making it ideal for continuous use where managing heat is important.
When not powering a load, it uses less than 0.2W. This helps reduce standby energy consumption, which is crucial in energy-efficient systems.
The device includes a built-in dial that lets you fine-tune the output voltage within a ±10% range. This flexibility helps meet the needs of various connected devices.
Thanks to its quality design and components, the LRS 35 12 delivers a steady, clean power supply. This helps protect connected equipment and extend its lifespan.
The LRS 35 12 includes protection for:
Short circuits
Overload conditions
High voltage spikes
These features keep both the power supply and connected devices safe from damage.
The unit meets several international safety standards:
UL60950-1
IEC/EN60950-1
IEC/EN60335-1
It also meets important signal interference standards such as:
EN55022 Class B
EN61000-4-2 through EN61000-4-6
These approvals ensure stable, interference-free operation in demanding environments.
The LRS 35 12 is ideal for a wide variety of uses, including:
It powers sensors, controllers, and PLCs in control systems and production environments.
With a 12V DC output, it suits LED strips, signage, and other lighting systems.
