This Malaysian Standard deals with all aspects of safety such as electrical, thermal and mechanical.
This standard applies to stationary, single-phase or polyphase, air-cooled (natural or forced) isolating transformers for the supply of group II medical locations, designed to be permanently connected to the fixed wiring of IT supply system, having a rated supply voltage not exceeding 1 000 V a.c. and rated frequency not exceeding 500 Hz. The rated output shall not be less than 3 kVA and shall not exceed 10 kVA.
NOTE 1 – Details of IT supply systems are to be found in IEC 60364-3.
NOTE 2 – The wiring rules for group II medical locations are under consideration [1]* .
The no-load output voltage and the rated output voltage shall not exceed 250 V a.c. singlephase
or polyphase (phase-to-phase voltage). Isolating transformers are used where double or reinforced insulation between circuits is required by the installation rules or by the appliance specification.
This standard is appli
