Hãng sản xuất: LUMEL VIET NAM
Mr. Bảo- Measurement and recording of 54 power network parameters in 1-phase 2-wire or 3-phase 3 or 4-wire balanced and unbalanced systems.
- Harmonics up to 51st for current and voltage
- Baclit LCD screen, fully configurable by a user
- 22 pages, 3 parameters in each
- 1 page with harmonics presentation
- Indications include the values of programmed ratios
- Memory of minimum and maximum values.
- 2 configurable alarm outputs.
- Mode of supervisory relay for alarm outputs - additional function
To make function active, please order appropriate licence key – details in ordering code. Function can be also activated on the devices which have been alredy installed on the facility after softwate upgrade. - Supervisory relay mode enables detection of following events:
- voltage drop or growth
- current drop or growth
- phase loss
- current or voltage unbalance
- phase sequence
- User can specify:
- the thresholds of monitored events
- monitoring of phase relay
- memory of relay state
- deley of switch-on/off relay
- relay state after the event has occured.
- Mode of supervisory relay for alarm outputs - additional function
- Optional: with additional module of analog outputs - S4AO type (4 current or voltage outputs)
- RS-485 digital output - MODBUS protocole
- Logging of up to 32 measured parameters in the internal memory 8 GB
- Modern and user-friendly Ethernet interface 10/100 BASE-T:
- protocol: MODBUS TCP/IP, HTTP, FTP,
- services: www server, ftp server, DHCP client
- protocol: MQTT - additional function
To make protocol active, please order appropriate licence key – details in ordering code. Protocol can be also activated on the devices which have been alredy installed on the facility after softwate upgrade.
- Wide range of voltage supply
- 85..253 V a.c. or 90..300 V d.c.
- 20..40 V a.c or 20..60 V d.c.
- Programming of parameters using free eCon software.
- Battery backup RTC.
- Modern design allows for installation of the meter in modular switchgear in accordance with EN 62208 (meter has a width of 6 modules) on 35 mm rail,
- External dimensions: 105 x 110 x 60mm.
