XS500, as it is known, carries dual safety certification: EN60950 2nd Edition for industrial applications and EN60601-1 2nd and 3rd Edition for medical applications, meeting the stringent creepage and clearance requirements.
Input to output isolation is 4kVac and “this can be tested on the complete power supply, simplifying system safety agency approvals”, said Excelsys.
2 MOPP (2 means of patient protection) is provided and leakage is under 300uA making it suitable for use in B (body) and BF (body floating) medical applications.
On top of this, designed to meet MIL810G, XS500 is compliant with SEMI F47 for voltage dips and interruptions as well as compliant with relevant EMC emission and immunity standards. It can withstand input surges of 4kV and has been characterised to MIL461F with an external EMI filter for high-rel and defence use.
Operation is from 90-264Vac and offers nominal outputs of 24V/21A and 48V/10.5A, both of which can be adjusted to to other values via the on-board potentiometer or Vtrim functions.
Control includes: remote on/off, power fail, remote sense and current limit adjust.
Protection includes over-voltage, over-current and over-temperature.
Options include I2C digital comms, OR-ing for N+1 redundancy, and conformal coating and ruggedisation for harsh environments.
Warranty is five years, and dimensions are: 323x128x39mm and 1.1kg
“Typical applications for the XS500 include medical systems such as imaging and blood processing equipment.,” said the Excelsys. “In particular, since no cooling fans are used, the units are ideal for medical systems that stipulate low audible noise specifications. The series also suits industrial, laboratory and hi-rel applications.”
