Mitsubishi Inverter Brake Resistor

The brake unit the resistor unit and the dischaging resistor must be installed on a nonflammable wall without holes.

Mitsubishi inverter brake resistor.

The inverter without a built in brake transistor can be connected. Twist the leads of the high duty brake resistor when increas ing their length 2m or more. When connected to a suitable inverter drive this will reduce the stop time by absorbing energy returning from the load. Otherwise a brake transistor failure or the like can overheat the brake resistor abnormally causing a fire.

Install the high duty brake resistor fr abr as follows. Otherwise the brake resistor may excessively overheat due to damage of the brake transistor and such causing a fire. Mitsubishi external dynamic braking resistor 60 0 ohms x 120 watts 0 12kw. Refer to the instruction manual of the inverter.

Via 4 3mm diameter holes. The inverter without a built in brake transistor can be connected. 240mm x 50mm x 21mm mounting. The brake resistor may be mounted horizontally or vertically depending on a suitable surface location.

Returns regeneration energy to the power supply enabling continuous regeneration operation. 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. 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. Increases the braking capability of the inverter which has a built in brake transistor.

Mitsubishi inverter option catalog 5 6 a700 1 2 3 regeneration unit option is necessary for regeneration. This could cause a fire and destroy the inverter. Increases the braking capability more than the brake resistor. Returns regeneration energy to the power supply enabling continuous.

Do not connect a resistor directly to the dc terminals p and n. This instruction manual gives handling information and precautions for use of this equipment. A high power factor converter whose. Use the alarm signal of the brake unit to switch power off.

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. The brake resistor may be mounted horizontally or vertically depending on a suitable surface location. The high duty brake resistor cannot be used with a brake unit high power factor converter power return converter built in brake etc. 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.

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. For use with fr d720s and fr e720s series inverters rated at 1 5kw or 2 2kw.
