2. Motor Control and Actuator Systems

Suitable for supplying power to the control circuits of small industrial motors, solenoid valves, and other actuators that operate on 24 V DC.

Problem Solved

The integrated Dynamic Current Limiting (DCL) technology is engineered to reliably trigger demanding inductive loads, such as motor starts or circuit breakers, by providing a temporary current boost without causing the power supply to shut down. This capability ensures smooth operation and prevents nuisance trips, thereby enhancing overall system uptime and operational efficiency.

3. Redundant Power Systems in Critical Infrastructure

Deployment in critical infrastructure applications such as emergency lighting, security surveillance systems, or continuous process monitoring, where uninterrupted power supply is paramount.

Problem Solved

The direct parallel connection option, facilitated by an integrated ORing MOSFET, allows for the creation of redundant power supply systems without the need for external diode modules. This significantly increases system availability and reliability; should one unit fail, others can seamlessly continue powering critical loads. The wide operating temperature range of -25°C to 70°C further contributes to its dependability in various demanding industrial environments.
