DRB Series

TDK DRB series of DIN rail power supplies are for low-power applications and 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 extremely-compact dimensions with industry-leading efficiency of up to 91% with no-load power consumption that 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 and 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 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 includes a three-year warranty.
