2385 Bench For Group Testing Of Electric Measurements And Machines Vocational Training Equipment Electrical Workbench
The electrical and mechanical characteristics of this bench of “universal” type enable to use this equipment in laboratories of electrical engineering for the implementation of experimental programs of electric measurements and machines; it is an alternative solution of bench mod. 2390. TRAINING PROGRAM: • Measurements of DC and AC voltage or current • Measurements of resistance • Measurements of DC and single-phase power • Measurements of frequency, capacitance and inductance • Measurements of three-phase active and reactive power • Measurements of power factor • Measurements on DC machines • Measurements on synchronous machines • Measurements on asynchronous machines • Measurements on transformers TECHNICAL SPECIFICATIONS: This bench is made of press-formed sheet steel and sections,chemically treated and painted with several coats of epoxyvarnish. The working top is of chipboard coated with bondedlaminate. Two drawers with flush-mounted handles and keylocks are fixed under the working top. The desk, that can bepositioned on the longer or smaller side of the bench, can beopened from the rear side for inspection and service. The described electric components are included in the desk. The control, protection and testing devices are mounted on thesilk-screen-printed fore plate of aluminium alloy ELECTRIC CHARACTERISTICS: • Main control device of electro-magnetic type, with key switch, high-sensitivity magneto-thermal differential circuit breaker and stop/emergency pushbutton • Service line with two single-phase sockets of 230 V and three-phase output 400 / N / PE with safety terminals, protected by four-pole magneto-thermal differential circuit breaker of 10 A • Variable three-phase line of 0-430 Vac / 0-500 Vdc – 5 A, protected by fuses, electro-magnetic control device and separate digital instruments for measuring AC and DC output voltages, safety terminals • AC-DC extra-low voltage line – 6-12-24-48 V – 4 A, protected by fuses, safety terminals • Control switch, protection fuses, terminals of use are prearranged for a regulated power supply unit of 12 V – 15 A Dimensions: 2000x1000x880 + 1000x450x350 mm (console) Net weight: 128 kg Supply with THEORETICAL – EXPERIMENTAL HANDBOOK
