M10-3640LED-06 three-phase autotransformer

Product Overview

The three-phase variable autotransformer M10-3640LED-06 is intended for use in test benches, electrical laboratories, maintenance departments, and service environments working with three-phase powered equipment. Its design allows simultaneous adjustment of all three phases by means of one common control shaft. This solution is practical in applications where fast and repeatable output voltage setting is required without separate adjustment of each phase.

The unit is equipped with an LED display for line output voltage indication, which allows continuous monitoring of the set value. A three-phase power switch simplifies operation and enables convenient switching during workshop or laboratory use. Additional protection is provided by over-current protection on each phase.

Key Features

• smooth output voltage adjustment in a three-phase system,
• input voltage (line): 3×400(380) VAC, 8 A, 50–60 Hz,
• output voltage (line): 3×0–450(430) VAC, 8 A,
• maximum power: 6000 VA,
• maximum current: 3×8 A,
• one common shaft rotating all output voltage sliders in parallel,
• three-phase power switch,
• three-phase input and output,
• over-current protection for each phase,
• LED display of output voltage (line).

Applications

This type of three-phase variable autotransformer is used wherever controlled variation of supply voltage is required in three-phase circuits. The unit can be applied in functional testing, equipment commissioning, service work, and educational or laboratory environments. The common control mechanism for all phases is particularly useful where convenient and repeatable voltage adjustment is required with straightforward manual operation.

• test and measurement benches,
• electrical and educational laboratories,
• service and commissioning of three-phase equipment,
• verification of equipment operation under variable supply voltage,
• technical applications requiring manual adjustment of three-phase voltage.

Operation Notes

The M10-3640LED-06 is intended for operation with three-phase input supply and adjustable three-phase output voltage over a wide range. Thanks to the common adjustment mechanism, the operator can set the required output voltage for all phases simultaneously. The LED display makes it possible to read the line output voltage directly without using an additional external indicator.

The unit measures 290 × 500 × 290 mm and weighs 30 kg, making it suitable mainly for stationary or semi-mobile workstations. In workshop and laboratory applications, important advantages include over-current protection on each phase and straightforward direct operation.
