POH-7/T

PROJECTOR POH-7/T (powered via telephone lines)

CERTIFICATE:
The intrinsically safe POH-7/T projector is designed for installation on mining machines and illuminating the selected observation point.
The intrinsically safe POH-7/T projector can be used in underground mines in non-methane and methane fields, in workings with any methane concentration. It is a category M1 device and its power supply does not have to be turned off in the event of an explosive atmosphere.
The POH7/T projector is designed to be powered from a telephone barrier (located in a non-hazardous area) via a twisted-pair telephone cable.
DESCRIPTION
The POH-7 projector housing is made of steel pipe. Inside, a radiator assembly with an electronics module, LED diode and lens is installed. Tempered glass is mounted in the front of the projector. The whole is closed by a nut with a gasket and a M16x1.5 cable inlet with a 3m long OLFLEX CLASSIC 110 Black 0.6/1kV 2 x 1.0 mm2 cable. The nut is secured against unscrewing with a mounting bracket.
The projector can also be supplied without a power cable. In this case, a cable with a maximum cross-section of 2x1.5 mm2 and an external diameter of 7.0 - 11.5 mm should be used
Once connected to power, the projector starts working immediately. No additional configuration is required.
The LED used in the projector is equipped with a lens that focuses light. The standard lens is a "MEDIUM" type with a beam angle (FWHM) of ~24°. At the customer's request, other types of lenses can be used according to the list below:
"SPOT" lens, light distribution angle (FWHM) ~12°, "S" marking
"DIFFUSER" lens, light distribution angle (FWHM) ~17°, "D" marking
"MEDIUM" lens, light distribution angle (FWHM) ~24°, "M" marking
"WIDE" lens, light distribution angle (FWHM) ~38°, "W" marking
"VERY WIDE" lens, light distribution angle (FWHM) ~63°, "V" marking
