FAQs
Install on TH35 DIN rails (TH35-15 or TH35-7.5) inside a compliant control cabinet. Mount the unit vertically with input and output terminals rated for 0.2–6 mm2. Ensure IP20 protection is maintained and allow the minimum mounting distance from other devices. Connect 24 V DC supply and load wiring per the data sheet to ensure safe operation.
Inputs: 24 V DC; Outputs: 24 V DC up to 20 A (480 W); Energy storage: 8000 Ws; Phase: 1; Operating range: -40 to +60 °C; Mounting: DIN rail TH35-15/TH35-7.5; Protection: IP20; Wire capacity: 0.2–6 mm2; Ideal for fast transient support and hold-up during power events.
Yes. The module carries CE and UKCA declarations and UL 508 certification, along with cUL recognition, RoHS and REACH compliance, and WEEE B2B classification. These certifications support global deployment and regulatory alignment for manufacturers and integrators across regions.
Applications include CNC machines, servo-driven conveyors, robotic cells, and other critical automation where rapid voltage recovery reduces downtime. The 8000 Ws energy reserve and 24 V–24 V power path help protect controllers and drives during transient dips, improving overall line throughput and machine availability.
Ultracapacitor-based modules offer high cycle life with minimal maintenance. Regular visual inspections, terminal torque verification, and periodic firmware or documentation reviews are advised. The module is designed for long service life in harsh environments, but proper disposal of energy storage components should follow local regulations at end-of-life.
