QS10.DNET 24V, 8A, DEVICENET® POWER SUPPLY POWER SUPPLY AC 100-240V Wide-range Input DeviceNet® Approved NEC Class 1 Compliant Width only 60mm Efficiency up to 93.4% Active Power Factor Correction (PFC) Negligible low Inrush Current Surge Short-term Operation down to 60Vac and up to 300Vac Full Power Between -25°C and +60°C DC-OK Relay Contact Quick-connect Spring-clamp Terminals 3 Year Warranty GENERAL DESCRIPTION SHORT-FORM DATA The QS10.DNET power supply is a derivate of the Dimension QS10 family, which is specially designed to meet the DeviceNet® requirement. The QS10.DNET exists beside the QS5.DNET, which is the right choice to supply networks that use NEC Class 2 cables. Output voltage Adjustment range Output current Output power Output ripple Input voltage Mains frequency AC Input current Power factor AC Inrush current Efficiency Losses Temperature range Derating Hold-up time Dimensions The specialties of DeviceNet® power supplies are: The nominal and overload currents are sized for the ratings of the DeviceNet® cables. Large load capacitors can be charged in a very short period of time. After turn on, the output voltage increases according to the DeviceNet® timing specification. The upper level of the output level is limited to protect the network. The most outstanding features are a high efficiency, compact size, wide-range input voltage, a very low inrush surge and a DC-ok contact. High immunity to transients and power surges and a low electromagnetic emission makes usage in nearly every environment possible. Unique quick-connect spring-clamp terminals allow a safe and fast installation. A large international approval package makes this unit suitable for nearly every situation. ORDER NUMBERS Power Supply Wall mount bracket Side mount bracket Buffer unit Dec. 2014 / Rev. 2.2 DS-QS10.DNET-EN All parameters are specified at 24V, 8A, 230Vac, 25°C ambient and after a 5 minutes run-in time unless otherwise noted. www.pulspower.com Phone +49 89 9278 0
