DIN rail power supplies for low power applications
TDK Corporation’s TDK-Lambda DRB series of DIN rail power supplies are for low power applications that require less space on the mounting rail.
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%. No load power consumption is between <0.3 W and <0.5 W depending on the model type.
Housed in a robust plastic case, the DRB series offer a narrow design, ranging from 18 mm to 45 mm, saving space on the DIN rail. The smallest model measures just 18 mm x 7 5mm 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 various applications. In addition, they have been rigorously tested for shock and vibration while mounted onto the rail.
The supplies operate from a universal input of 85~264 V ac and have EN61000-3-2 compliance, enabling worldwide use; moreover, they can withstand input voltage surges of 30 0V ac for 5 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, 24-28 V or 48 V dc.
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 40mV and a green LED indicates dc OK. Other features include over-current, over-voltage protection and a hold-up time of up to 20ms at 100 V ac input voltage, full load.
