Convection-cooled, low-cost DIN Rail Power Supplies – DRB SeriesTDK Corporation is introducing the TDK-Lambda DRB series of DIN rail power supplies for low-power applications that require keenly priced basic functionality. Designed to support the growing trend for simple and economic DIN power products in industrial, building automation and process control applications, the DRB series combines low cost and compact dimensions with efficiency of up to 91 per cent. No load power consumption is between <0.3W and <0.5W depending on the model type.

Martin Southam, Director of Marketing, TDK-Lambda EMEA, says: “There’s strong customer demand for compact, convection-cooled DIN rail power supplies that deliver their rated power without compromising long-term reliability. Housed in a robust plastic case, the DRB supplies feature a narrow design, ranging from 18mm to 45mm, saving space on the DIN rail. We believe that these are the smallest products of their kind on the market. The DRB series is also perfect for customers working to ErP or Eco-Design guidelines.”

These supplies operate from a universal input of 85~264V AC and have EN61000-3-2 compliance, enabling worldwide use; moreover, they can withstand voltage of 300V AC surge for 5 seconds. The DRB series is available with four output power levels ranging from 15–100W and nominal output voltages of 5V, 12–15V, 24V or 48V DC. The supplies can operate at full load over a wide temperature range of -10 to +55degC (+70degC for 15W model). Typical ripple and noise is below 40mV 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 100V AC input voltage, full load.

The smallest model measures 18mm × 75mm × 90mm (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.

TDK’s 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.
