The PSU complies with all major safety approvals for EU (EN 60 950, EN 60204-1, EN 50178), USA (UL 60950, UL508 LISTED), Canada (CAN/CSA-C22.2 No 60950 [CUR], CAN/CSA-C22.2 No. 14 [CUL]), CB Scheme (IEC 60950). NEC Class 2 Power Supply

Design details – for your advantage:

• All terminals are easy to reach as mounted on the front panel.

• Input and output are strictly apart from each other (input below, output above) and so cannot be mixed up

• Mounting and connection do not require any screwdriver

→ Easy, quick, durable and reliable installation
