DRB480 – 93% efficient 480 W DIN rail power supply

TDK-Lambda announces the introduction of the 480W rated DRB480-24-1 DIN rail mount AC-DC power supply with a power density of 6 Watts per cubic inch. Featuring a narrow width, the DRB480 is ideally suited for enclosures and cabinets where space is at a premium. With an average efficiency of greater than 87%, the DRB480 meets ErP standards.γ€€

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 – 264Vac 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.γ€€

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

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.
