Three-phase digital panel meter

( ECM603/603H )

Description The ECM603 series three-phase digital panel meters are suit for 220V (L-N)/ 380V (L-L) low voltage system. The ECM603H is suit for up to 35 kV system. (input voltage is 57.7/100V). ECM603 and ECM603H are designed for monitoring and displaying electric parameters include voltage, current, active power, reactive power, power factor, frequency, active energy and reactive energy. The devices are user-configurable and can replace numerous single function meters. There are optional modules for different requirement, which are 4-20mA analog output, status input, relay alarm output and RS485 com.   Feature 3 line LED, high definition and brightness Sampling AC data in single or three phase system Optional single parameter measure or integrated measure External CT programmable (PT programmable as well in ECM603H) RS485 communication/ MODBUS protocol Password protect   Performance Index Standard: DLT721-2000, IEC61000-4 Accuracy: Voltage: 0.5% Current : 0.5% Power: 1.0% Active energy: class 1 Power loss＜2VA Power frequency withstand voltage: AC2kV/ min. ~1mA Input--Output--Power Insulation resistance ＞50MΩ Impulse withstand voltage: 5kV (peak), 1.2/50uS Input range: Current: AC 0~5A Voltage: 0~220VAC Frequency: 50~60Hz Overload capability: 120% of rated current or voltage Communication: RS485 port/ MODBUS protocol Baud rate: 4800/ 9600bps Address: 1~ 247 Analog output load resistance:400Ω Relay output: 250VAC/5A, 30VDC/5A Status input: external power supply Electrical fast transient/burst immunity test: IEC61000-4-4, Level 4 Surge immunity test: IEC61000-4-5, Level-3 Electrostatic discharge immunity test: IEC61000-4-2, Level 4 Operating temperature: -40~ 70℃ Storage temperature: -50~85℃ Humidity: 5~95%, non-condensing
