 Linear/1 UPS Isolated Medical Grade UPS: (formerly the Best Unity UPS)

  Features

Uninterruptible power supply UL-approved for use in hospital, medical, and laboratory power applications requiring low leakage(less than 100 micro amps) UPS power systems for human interfaces.

Linear/1 is an isolated, medical-grade UPS designed for the demands of professional service. The linear/1 features no-break transfers, high surge capability, multiple voltage outputs and ultra-low leakage current to minimize patient risk.

The Linear/1 is designed to be compatible with all modern loads and is especially suited to today's power-factor corrected equipment requiring Unity power factor.

  • UL544 standard for hospital grade, medical grade, and ideal for dental equipment use.
  • Designed for linear and non-linear loads
  • Unity Power Factor
  • Single Phase pure sine wave UPS
