500W power supply features a typical efficiency of 92%

The device’s high efficiency enables low heat generation, which when combined with its low energy loss topologies, increases reliability and service life by keeping temperatures to a minimum. 

Offered with nominal outputs of 24V/21A and 48V/10.5A, the wide voltage adjustment range of the power supply can accommodate non-standard system voltages via the on-board potentiometer and Vtrim functions. The XS500 features remote on/off, power fail, remote sense and current limit adjustment control signals, along with overvoltage, overcurrent and overtemperature protections.

The device carries dual safety certification: EN60950 2nd Edition for industrial applications and EN60601-1 2nd and 3rd Edition for medical applications. To simplify system safety agency approvals, the power supply’s 4KVAC input to output isolation can be tested on the complete power supply. Featuring 2 MOPP and a leakage current of less than 300uA, the XS500 is suitable for use in B (body) and BF (body floating) type medical applications.

The power supply, which is designed to meet MIL810G, is compliant with SEMI F47 and all relevant EMC emission and immunity standards. Designed for use in hostile environments, the device can withstand input surges of 4KV and has been characterised to MIL461F with an external EMI filter for Hi-Rel/Defence applications.

The XS500 is optionally available with I²C digital communications and an OR-ing function for N+1 redundancy. For use in harsh environments, the device can be conformal coated and ruggedised. The power supply is suitable for medical systems such as imaging and blood processing equipment.
