A
Product description
STEP POWER power supplies for distribution boards. The STEP POWER power supplies with Push-in connection technology are the professional
solution for intelligent building automation. The compact devices are economical, space-saving, and flexible in application.
Your advantages
• Energy savings with the highest level of efficiency in no-load and part-load operation (Efficiency Level VI)
• Space savings in the control cabinet due to the narrow design combined with increased performance (up to 100%)
• Approval for household purposes (EN 60335) allows use in domestic applications
• Quick and easy startup with tool-free Push-in connection technology at a 45° angle with double terminal points
• Flexible mounting: Snap onto a DIN rail or screw onto a level surface
