Mitsubishi Inverter Brake Resistor

Increases the braking capability more than the brake resistor.

Mitsubishi inverter brake resistor.

Otherwise the brake resistor may excessively overheat due to damage of the brake transistor and such causing a fire. The high duty brake resistor cannot be used with a brake unit high power factor converter power return converter built in brake etc. Otherwise a brake transistor failure or the like can overheat the brake resistor abnormally causing a fire. The wire size used should be minimum 14 awg 2 1mm2.

Via 4 3mm diameter holes. 240mm x 50mm x 21mm mounting. Returns regeneration energy to the power supply enabling continuous. Do not connect a resistor directly to the dc terminals p and n.

Some drive models come come with a large brake transistor built in you can find their minimum resistance and max braking power in the drives with internal braking transistors table. The brake resistor may be mounted horizontally or vertically depending on a suitable surface location. Mitsubishi external dynamic braking resistor 60 0 ohms x 120 watts 0 12kw. Thank you for choosing this mitsubishi inverter option unit.

Mount the brake resistor on an incombustible surface. Installing the inverter directly on or near a combustible surface could lead to a fire. A high power factor converter whose. When the brake resistor is mounted externally to the enclosure housing the inverter install a solid type 1 enclosure at least 8 times the volume size of the brake resistor that incorporates mesh or perforated steel type ventilation.

Twist the leads of the high duty brake resistor when increas ing their length 2m or more. This could cause a fire and destroy the inverter. The surface temperature of braking resistors can far exceed 100 c for brief periods. The brake unit the resistor unit and the dischaging resistor must be installed on a nonflammable wall without holes.

Mitsubishi inverter option catalog 5 6 a700 1 2 3 regeneration unit option is necessary for regeneration. Refer to the instruction manual of the inverter. Increases the braking capability of the inverter which has a built in brake transistor. For use with fr d720s and fr e720s series inverters rated at 1 5kw or 2 2kw.

Use the alarm signal of the brake unit to switch power off. Returns regeneration energy to the power supply enabling continuous regeneration operation. The inverter without a built in brake transistor can be connected. When connected to a suitable inverter drive this will reduce the stop time by absorbing energy returning from the load.

This instruction manual gives handling information and precautions for use of this equipment. The inverter without a built in brake transistor can be connected. If you are purchasing a braking unit from mitsubishi you can find your appropriate resistor by looking at the brake resistors for brake units table.
