Standard Outfit:
1 set of resistors, consisting of resistance grids or of windings on ceramic-tubes, material CuNi 44, shunting by rotary switches, amperage adjustable from 0,1 A up to the maximum amperage in steps of 0,1A,maximum voltage during continuous operation 230 V or 275 V,
1 main contactor, with illuminated push-button keys ON/OFF, remote control connection feasibility, pilot lamp and two terminals, with excess temperature release,
1 blower with rate of air flow corresponding to the developing heat loss, connecting piece for cooling and exhaust air situated by agreement.
Design: primarily determined as slide-in module for power supplies, see PTL prospectus N 03e, under secondary consideration also available as cabinet, housing made of sectional steel and sheet steel, sprayed with papyrus-white structure varnish, service components and indicators on front or alternatively by agreement, e. g. in case of small powers in the testing machine, in case of high powers in a separate cabinet or in a separate room.
Special outfit :
Additional connection for different make and break currents,
Additional connection for reaching of maximum amperage with power factors cos 0,6, 0,5 and 0,3 too, with excess voltage monitoring,
Voltage and amperage indicating instruments, additional load for higher amperages at 50 % switch-on rate or less, signal output and cut-off in case of break of the specimen.
Air core inductors: see PTL Prospectus N 03Ce
