Specifications |
Dimension Q Series. PULS' Q series DIN rail power supplies combine compact size with high efficiency thanks to their advanced detailed design and synchronous rectification. This, along with a 150% short-term maximum peak power capability and large integrated output capacitors, facilitates motor starting, capacitor charging, and reverse energy absorption, often allowing the use of lower power class equipment. Excellent immunity to transients and power surges, combined with low electromagnetic emissions, allows these PSUs to be used in almost any environment. Installation and use are simplified thanks to the integrated output power manager, wide-range input voltage design, and virtually zero input inrush current. Power supply diagnostics are easy with the Q series thanks to the dry DC OK contact, green DC OK LED, and red overload LED. Unique quick-connect spring clamp terminals ensure safe and fast installation, while numerous international approvals for a wide range of applications make them ideal for almost any situation. .
