This Part of this standard specifies requirements for the construction and testing of a range of mains fed power supply units intended to be certified intrinsically safe for use in coal mines and which provide an intrinsically safe a.c. output of the following voltages:
- a 12 V r.m.s. output to supply intrinsically safe apparatus where maximum power availability is the predominant requirement;
- a 15 V r.m.s. output to supply intrinsically safe apparatus where a higher operating voltage is more important than available power.
It is intended that the components forming the power supply circuit be assembled on to a chassis that may be incorporated within either a flameproof enclosure or, where the power supply unit is located outside a potentially explosive atmosphere, within some other suitable enclosure. Requirements for these enclosures are not given in this standard.
