First, LM-511F product brief

LM-511F low-voltage motor integrated protection device using single-chip microprocessors chip and modern microelectronic control technology development and design.

LM-511F low-voltage motor integrated protection device can be measured information, switch status and displacement information, protection action signal,

SOE event content, protection settings parameters, etc. uploaded to the background monitoring host,

constitute the motor motor control center, to achieve the remote Centralized management and monitoring.

.LM-511F low-voltage motor integrated protection device can truly digital, intelligent, network, to protect and control and integration.

LM-511F low-voltage motor integrated protection device using RS485 communication interface and standard Modbus protocol,

Second, LM-511F industry background

There are a number of factors related to the selection of the protector, such as the installation location, power supply,

and the distribution system with the same; also consider the new motor protection configuration,

or to upgrade the motor protection, or accident motor Protection of the perfect, etc.

Selection should also pay attention to control mode manual, automatic, local control, remote control, stand-alone operation,

the production line centralized control and so on. The motor protector (motor protector) is to detect the changes in line current (including taking, positive sequence, negative sequence, zero, and so on.)

The motor protector (motor protector) Sequence and overcurrent) for the principle that the phase or overload signal can be detected.

In addition to the off-phase protection function, but also has the overload, stall protection function.

To understand the model specifications, motor function characteristics, protection type, rated voltage, rated current, rated power, power frequency, insulation level.

This content can basically give users how to properly use and maintain and select the protector to provide a reference
