Overload behaviour

PULS Overload Design™: No switch-off at

overload/short-circuit, instead: up to 1.4

So you need no oversizing to start awkward

loads.

Protection

Unit is protected against (also permanent) short-

circuit, overload and open-circuit.

The PSU complies with all major safety approvals for EU (EN 60 950,

EN 60204-1, EN 50178), USA (UL 60950, E137006, UL508 LISTED, E198865),

Canada (CAN/CSA-C22.2 No 60950 [CUR], CAN/CSA-C22.2 No. 14 [CUL]),

Limited Power Source NEC Class 2 and Hazardous Location Class I Div. 2

according to UL1604.

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, out-

put above) and so cannot be mixed up.

• Mounting and connection do not require any screwdriver

→ Easy, quick, durable and reliable installation.
