PULS DIMENSION UB20.241 DIN Rail Power Supply 24V DC 20A 480W

The PULS DIMENSION UB20.241 stands out with its high efficiency of up to 95.6% and active power factor correction, minimizing energy losses and reducing harmonic distortion on the mains. It delivers a stable 24 V DC output with 20 A current, making it suitable for demanding industrial applications.

Highlights

• Wide input voltage range: 100-240 V AC (85-276 V AC operating) and 88-300 V DC
• Adjustable output voltage: 24-28 V DC
• Convection cooled, no internal fan required
• Parallel capable for increased power or redundancy
• Robust metal housing for harsh environments

In daily use

This DIN rail power supply is designed for continuous operation in control cabinets. Its hold-up time of more than 20 ms at 115 V AC ensures reliable performance during brief mains interruptions. The output ripple and noise are kept below 50 mVpp, providing clean power for sensitive loads.
