Branch Circuit Power Meter

( ECM202 )

Description ECM202 Branch Circuit Power Meter is specially designed for monitoring Power supply distribution cabinet in data center, which can monitor incoming circuit and outgoing circuit parameters, DI/DO status, fulfill monitoring for power supply distribution cabinet and alarming for abnormal voltage and current information. 7 inch HMI with system chart display which can best fulfill visuality and operability, customer can choose 21st – 168st (Unit: 21st) outgoing circuit by load quantity. This ECM202 also provide extra communication port which can easily connect with other systems. Application 1. Load management 2. Data Center 3. Telecommunication Function 1. Measuring: 1 main circuit  +  42  branch circuits 2. DI/DO: 4 status inputs (dry contact) , 2 relay outputs, 1 pulse output 3. Settable Pre-Alarm function: Main circuit:  Alarm for voltage, current, current    unbalance (optional alarm for leakage current/ temperature alarm) Branch circuit: Alarm for current  (lo-lo-limit, lo-limit, hi-limit, hi-hi-limit) 4. Communication:  RS485,  support Modbus-RTU protocol 5. Phase sequence of branch circuit is programmable 6. Optional CT input for branch circuit:  50A, 100A, 200A 7. Settable wiring for branch circuit:  Either single phase or 3 phase 8.
