TDK-Lambdavisit website

 

TDK Corporation is introducing the 480W rated DRB480-24-1 DIN rail mount AC-DC power supply with a power density of 6Watts per inch3. Featuring a narrow width, the DRB480 is well suited for enclosures and cabinets where space is at a premium. With an average efficiency of greater than 87 per cent, the DRB480 meets ErP standards.

Housed in a robust metal enclosure, the DRB480 has a depth of 124mm, a height of 125mm and a width of 84mm. The power supply can operate from a wide range 90–264V AC input allowing use globally. The DRB480-24-1 has 24V 20A output and features a DC OK signal in addition to an LED indicator. The output can be adjusted from 24–26.4V to compensate for series blocking diodes or FETs in redundant configurations.

The input to output isolation is 3000V AC, input to ground 1500V AC and the output to ground is 500V AC. The DRB is convection cooled and is rated for operation in -20 to +70degC ambient temperatures (cold start at -30degC), with linear derating above 50degC to 62.5 per cent load at 70degC. Electrolytic capacitor temperatures have been carefully considered to ensure their life is greater than 7 years in a 40degC ambient at 230V AC input, with 75 per cent load, operating 24 hours a day.

The unit is certified to IEC/EN/UL/CSA 60950-1, UL 508, and is CE marked for the Low Voltage, EMC and RoHS2 Directives. It meets EN55011-B, EN55022-B, CISPR11-B, CISPR22-B, EN61204-3 Class A radiated and conducted emissions, and complies with both EN 61000-3-2 Class A harmonic currents and EN61000-4 immunity standards.
