TDK Corporation is introducing the TDK-Lambda brand DRF960 24 1 DIN rail mount AC-DC power supply, rated at 24V 40A (960W) with a 60A (1440W) peak for 4s. The product has a very narrow 110mm width, freeing additional space for other DIN rail mount assemblies.
With an efficiency of 95 per cent, significantly less internal heat is generated, resulting in cooler electrolytic capacitors. Operating field life is calculated at greater than 10 years at 75 per cent load, 40degC ambient, and 230V AC input. This energy efficient power supply is suitable for a wide range of industrial applications including factory automation, process control and test and measurement equipment.
The 24V output is adjustable from 24 to 28V, using the front panel potentiometer or an external 5 to 6V DC source, to compensate for blocking diodes or FETs in redundant configurations. Also provided as standard is a DC OK relay contact, rated at 30V 1A, and remote on/off functionality. The DRF960 power consumption is less than 1W to reduce energy consumption when the output is inhibited. Up to five units can be connected together in parallel when set in droop mode current share.
TDK’s DRF960 is housed in a robust metal enclosure, measuring 123.4mm in height, 139mm deep and a width of just 110mm. The power supply can operate from a wide range 180–264V AC, 47–63Hz input. Input to output isolation is 3000V AC, input to ground 1500V AC and output to ground 500V AC. The DRF960 is rated for operation in –25degC to +70degC ambient temperatures (40degC cold start), derating linearly above 60degC to 50 per cent load at 70degC.
The unit is safety certified to IEC/EN/UL/CSA 60950-1, UL 508 and is CE marked for the Low Voltage, EMC and RoHS Directives. The unit meets EN 55032-B radiated and conducted emissions, and complies with the EN 61000-4 immunity standards.
