Siemens DIN-rail power supply unit (DIN-rail

The 3-phase basic unit with 20 A has been innovated and, with a width of only 70 mm, is one of the most compact in its power class. A signaling contact for monitoring the operating status is now integrated, and the input voltage range has been expanded to 320 – 575 V. With an efficiency of up to 93%, the regulated power supply SITOP PSU300M 24V/20A is extremely efficient, resulting in low heat generation in the control cabinet. The extra power with 1.5 times the nominal current for 5 seconds allows for the easy switching on of consumers with high inrush current.

Advantages at a glance:

• Regulated power supply for the highest demands
• Power boost with 3 times the nominal current
• Operating status indicated by 3 LED displays
• Selectable short-circuit behavior: automatic restart or latching shutdown
• Parallel connection possible for increased power
• Space-saving with only 70 mm width, no side installation distances required
• Wide-range input 3 AC 320 to 575 V for various network voltages and to compensate for voltage fluctuations
• 1.5 times extra power for switching on consumers with high inrush current
• Up to 93% efficiency
• Integrated signaling contact "DC 24 V o.k.".
