Diode Testing Machine

Sharang Corporation offers a Diode Testing Machine designed for testing the stripe packed diodes having 5 mm pitch for their leakage current at the rated PIV voltage. The machine comprises of a motorised bucket conveyor with 5 mm pitch and slip ring type arrangement for applying the voltage to the diode during its propulsion. The electronic controller is designed for generating the fixed regulated DC voltages (3), viz., 100, 400 and 1000 V. The electronic controller has digital voltage and micro amp indication. The controller has a precision leakage current detection arrangement where by a leakage current as low as 3 and 5 micro amp is detected and conveyor is stopped as soon as diode under test draws a leakage current higher than 3 or 5 micro amp. A buzzer sounds to indicate a faulty diode. The conveyor and controller are mounted on the same chassis. Brief specifications: supply – 230 V AC; motor – AC synchronous; testing speed – 3 diodes per sec; testing voltages [selectable] –100/400/1000 V DC; leakage current selection – 3 or 5 micro amps; and additional accessories and attachments – 10 mm pitched bucket replaceable to 5 mm pitched bucket suitable for testing 1N 5408 Type diodes will be supplied at extra cost. The existing machine is suitable for rectangular sized diodes packing box and not for circular role type packing so the circular packing handling arm will be supplied at extra cost.
