Industry:  Robotics  
Application: Charge Super Capacitor
Power Solution: HLG-120H-C Driver
 
As robotics technology advances, manufacturers face the challenge of finding reliable, efficient, and cost-effective power solutions for their systems. Increasingly, companies are exploring the repurposing of LED drivers as effective charging solutions.
 
CUSTOMER PAIN POINTS:

• Charging super capacitors presents a challenge because most power supplies cannot deliver a stable constant current down to 0Vdc, nor do they offer the ability to control the charging rate. Which are essential for safe and efficient operation in advanced electronic systems.

• Space limitations: Robotic systems often require compact, waterproof, and fanless power solutions to meet tight spatial constraints—especially for applications where reliability and durability are critical.
