Mitsubishi Inverter Brake Resistor

The brake resistor may be mounted horizontally or vertically depending on a suitable surface location.

Mitsubishi inverter brake resistor.

Mount the brake resistor on an incombustible surface. Otherwise the brake resistor may excessively overheat due to damage of the brake transistor and such causing a fire. 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. Installing the inverter directly on or near a combustible surface could lead to a fire.

The wire size used should be minimum 14 awg 2 1mm2. 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. The brake unit the resistor unit and the dischaging resistor must be installed on a nonflammable wall without holes. The inverter without a built in brake transistor can be connected.

Thank you for choosing this mitsubishi inverter option unit. When connected to a suitable inverter drive this will reduce the stop time by absorbing energy returning from the load. Increases the braking capability of the inverter which has a built in brake transistor. 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.

Refer to the instruction manual of the inverter. A high power factor converter whose. This instruction manual gives handling information and precautions for use of this equipment. 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.

Do not connect a resistor directly to the dc terminals p and n. Mitsubishi external dynamic braking resistor 60 0 ohms x 120 watts 0 12kw. Twist the leads of the high duty brake resistor when increas ing their length 2m or more. The inverter without a built in brake transistor can be connected.

Increases the braking capability more than the brake resistor. Install the high duty brake resistor fr abr as follows. For use with fr d720s and fr e720s series inverters rated at 1 5kw or 2 2kw. This could cause a fire and destroy the inverter.

Otherwise a brake transistor failure or the like can overheat the brake resistor abnormally causing a fire. The surface temperature of braking resistors can far exceed 100 c for brief periods. The high duty brake resistor cannot be used with a brake unit high power factor converter power return converter built in brake etc. Via 4 3mm diameter holes.

The brake resistor may be mounted horizontally or vertically depending on a suitable surface location. 240mm x 50mm x 21mm mounting. Returns regeneration energy to the power supply enabling continuous regeneration operation.
