QS5.DNET 24V, 3.8A, NEC CLASS 2, DEVICENET® POWER SUPPLY POWER SUPPLY AC 100-240V Wide-range Input DeviceNet® Approved NEC Class 2 Compliant Width only 40mm Efficiency up to 92% Active Power Factor Correction (PFC) DC Input from 88 to 360Vdc 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 QS5.DNET power supply is a derivate of the Dimension QS5 family, which is specially designed to meet the DeviceNet® requirement. The QS5.DNET exists beside the QS10.DNET, which is the right choice to supply networks with the thick 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 Mar. 2013 / Rev. 2.2 DS-QS5.DNET-EN All parameters are specified at 24V, 3.8A, 230Vac, 25°C ambient and after a 5 minutes run-in time unless otherwise noted. www.pulspower.com Phone +49 89 9278 0
