| DMP Type DMP Electronic Motor Protection Relay (EMPR) |
|
| Characteristics |
|
|
Digital EMPR with Built-in Microprocessor Control Unit (MCU) |
|
All models of EMPR, which have characteristics of perfect digital with built-in MCU, features excellent reliability by materializing real-time data processing & high precision. |
|
| Various Motor Protective Functions |
DMP demonstrates excellent motor protective function by protecting motors against Over-current, Phase failure, Asymmetry, Lock, Reverse phase and Undercurrent. It has also option of ground fault or short circuit protection, as required.
|
|
| Common Usage of Unified and Extension Types |
The display unit can be detached from the main relay, if required, and can be fitted on to the MCC / Panel door to enable user verify various causes of faults, values of faults, and values of current without opening the door. Alternatively, it can also be installed inside the MCC / Panel as a complete assembly form.
|
|
| Common Use of the Screw connection-type and Tunnel-type Terminals |
| The removable terminal base can be attached to various installation environments. |
|
| Indicates Cause and Values of Faults |
|
While the cause and Values of Faults are indicated on the digital display, DMP also indicates load factors during operation. This function enables users to check the operating status of motor at all times. |
|
| DMP models have facility of 3-phase digital ampere-meter function |
|
| Selectable either Inverse time or definite time characteristics |
|
User can select desired inverse or definite time characteristics depending upon the application and its requirement. |
|
| Applicable to Inverter Circuit |
|
DMP performs well against high-frequency noise, and its applicable to inverter circuit. |
| The applicable frequency ranges from 20Hz to 200Hz. |
|
|
Awarded "Good Design of 1999" Mark DMP was awarded "Good Design of 1999" Mark for its elegant appearance and excellent design. |
