Convection-cooled DIN rail power supplies offer cost saving benefits
Designed to support the growing trend for simple and economic DIN power solutions in industrial, building automation and process control applications, the DRB series combines low cost and compact dimensions with industry leading efficiency of up to 91%. No load power consumption is between <0.3 W and <0.5 W depending on the model type.
The supplies operate from a universal input of 85~264Vac and have EN61000-3-2 compliance, enabling worldwide use; moreover, they can withstand voltage of 300 Vac surge for five seconds. The DRB series is available with 4 output power levels ranging from 15 – 100 W and nominal output voltages of 5 V, 12-15 V, 24 V or 48 Vdc.
The supplies can operate at full load over a wide temperature range of -10 to +55°C (+70°C for 15 W model). Typical ripple and noise is below 40 mV and a green LED indicates DC OK. Other features include over current and over voltage protection, and a hold-up time of up to 20 ms at 100Vac input voltage, full load.
The smallest model measures just 18 mm x 75 mm x 90 mm (DRB15-24-1); all DRB models will mount on either a TS35/7.5 or TS35/15 DIN rail offering engineers a flexible option for the various applications. In addition, they have been rigorously tested for shock and vibration while mounted onto the rail.
The DRB series is approved to UL508 safety standard for industrial control equipment. Further safety approvals include IEC/EN 60950-1 (2nd Ed.) and UL/CSA 60950-1. CE marked in accordance with the LV Directive, EMC Directive and RoHS Directive, the power supplies are designed to meet EN55022 and CISPR22 Class B for conducted and radiated EMI, and include a three-year warranty.
