500-W convection cooled supply offers 92% efficiency

The XS500 series of high-efficiency, 500-W convection-cooled ac/dc power supplies feature a typical efficiency of 92% and operate from 90 to 264 Vac. The supplies target motors, pumps, fans, compressors, and capacitor banks that have loads requiring very high instantaneous transient current delivery capabilities beyond 500 W at startup. The units suit medical systems that stipulate low audible noise, including a wide range of industrial, laboratory and high-reliability applications.

The power supplies are offered with nominal outputs of 24 V/21 A and 48 V/10.5 A, and can accommodate non-standard system voltages via the on-board potentiometer and V_trim functions. Standard protection features and control signals include remote on/off, power fail, remote sense, current limit adjustment, as well as overvoltage, over-current and over-temperature protection. The series also provides input to output isolation of 4KVAC, which allows hi-pot testing to be conducted on the complete power supply.
