Medical Grade Plug-In Line Isolation Transformers 178, 240, 289, 298 "MG" Series

cULus and CSA Listed

English | Français

Features:

  • Intended for non-patient connected indoor applications where protection of sensitive electronics is required:
    • High end audio / studio use
    • Medical electronics
    • High end test equipment / laboratory
  • cULus Listed to UL 60601-1 (1st Edition) and CAN/CSA-C22.2 No. 601.1-M90 (R2005).
  • Each unit provides complete line isolation and noise filtering plus utilizes a Faraday shield to reduce leakage currents below UL60601-1 requirements (under 100 microamps).
  • Reduced noise coupling due to floating AC output.
  • Not intended to be used to supply power to life support appliances. 
  • 3 different VA Capacities available - -  500VA, 1000VA, and 1800VA.  All rated 50/60Hz.
  • 4 different electrical configurations;
    • 120V-120V straight isolation ("178" series)
    • 240V-240V straight isolation ("240" series)
    • 240V-120V step down isolation ("289" series)
    • 120V-240V step up isolation ("298" series)

 

  • Vented 14 gauge steel housing with white powder paint
  • Hospital Grade 3-wire grounded Input Plug (see chart).
  • 2 or 3 Duplex Hospital Grade Output Receptacles (see chart).
  • On-Off Switch / Circuit Breaker combo protected, and built in automatic Thermal Cut Out for added protection.
