ScannerMAX Power Supply

Product Description

The UP150D is an open-frame, dual-output, switch-mode power supply that has been made for use along with our Mach-DSP servo driver. Thanks to its compact size, the UP150D can be located close to the Mach-DSP servo driver inside a scan head or other commonly used industry and lab setups. This power supply features high efficiency, and it can be operated at continuous power levels up to 120W without cooling, or greater than 150W with a modest 20CFM cooling fan.

Features of the UP150D

  • High efficiency of 87%. This allows for short-term operation up to 180W during very demanding portions of a scan pattern.
  • Active power factor correction and built in short-circuit, overload, and over-voltage protection.
  • Dual-output with a green LED that indicates if +/-24V power is present.

Although it is somewhat counter-intuitive, power supplies are specified in terms of “average current” (related to the power being delivered) while scanners are specified in terms of “RMS current” (related to the heating of the scanner coil). Because of this, it is not a simple matter to gage power supply requirements by referring to the RMS current specification found on a scanner’s datasheet. Average current supplied by the power supply will always be lower than RMS current driven into the scanner. Moreover, if a scanner is consuming 2 amps of current, half of this current is supplied by the positive supply rail and the other half is supplied by the negative supply rail (i.e. 1 amp from each supply rail). This is why, for most applications, the UP150D should be adequate for use with any of our scanners, including the ScannerMAX Saturn 9 with 10mm mirrors.
