**You can measure power with a direct connection to an already-installed large-capacity general-purpose CT (secondary side 1 A / 5 A type).** 

* The dedicated CT for Eco-POWER METER[®] cannot be used. Use a CT with a secondary side current of 1 A / 5 A.

The measuring accuracy of the Eco-POWER METER[®] does not take the CT error into account. Other Eco-POWER METER[®] series (except **KW2M** and **AKW8115** ) need to use two CTs for measurement. **KW9M** is ready for direct input from only one CT, allowing higher accuracy measurements than with other Eco-POWER METER[®] series.

- *1 Without error of current transformers (CT) and voltage transformers (VT) 

- *2 As to the current under 5 % of rating, it may not satisfy the accuracy according to CT setting (max. error; 0.5 %). 

- It measures from 0.1 % of CT secondary current. 

- IEC62053 is the international standard for Electricity metering equipment.

## **■COMMUNICATION SPECIFICATIONS**

Interface Conforming to RS485 Communication method Half-duplex Synchronous system Synchronous communication method Isolation status Isolated with the internal circuits Protocol MEWTOCOL, MODBUS (RTU), DL/T645-2007*1 (select with setting mode) Number of connected unit 99 (max.)*2 Transmission distance 1,200 m 3,937 ft*3 Transmission speed[38,400, 19,200, 9,600, 4,800, 2,400, 1,200 bps ] (select with setting mode) Data length 8bit (fixed) Transmission format Parity Not available / odd number / even number (select with setting mode) Stop bit 1bit, 2bit (select with setting mode) 

- Varistor is mounted internal as a protection element. 

Install a protective device in case of using at the place where it effects by surge. How to calculate 

- (1) Calculate the appropriate power to be measured from the unit of the integral power pulse output. Unit for pulse output > (Max. measurement power [kW]) / (3,600 sec × 1 pulse/sec) 

   - When the pulse output unit is 0.001, the maximum power that can be properly measured by pulse output is 3.6 kW (3,600 sec × 1 pulse/sec × 0.001). If the load is higher than this value, the output pulses cannot keep up with it, and the number of pulses becomes small. In such cases, set the pulse output unit to the value immediately above. 

- (2) Calculate the appropriate pulse output unit from the instantaneous power to be measured. (Max. measurement power [kW]/3,600 sec × 1 pulse/sec) < Unit for pulse output When the maximum power to be measured is 10 kW, the pulse output unit required for the correct pulse output is 0.01 kWh/pulse, which is the value immediately above this one: 10 W/3,600 sec x 1 pulse/sec = 0.0027 

- *1 MEWTOCOL is the protocol for PLC from Panasonic. DL/T645 is the China power-meter standard. Only DL/T645-2007 is supported. 

- *2 For RS485 converter on the computer side, we recommend SI-35 and SI-35USB (from LINE EYE Co., Ltd.). When using SI-35, SI-35USB or PLC from our company (which can be connected up to 99 units), up to 99 can be connected. In case using this system with the other devices, up to 31 can be connected. 

Notes: 

- 1) If the pulse output unit is set to output one pulse or more per second, the EcoPOWER METER[®] cannot correctly output pulses. 

   - *3 Please check with the actual devices when some commercial devices with RS485 interface are connected. The number of connected devices, transmission distance, and transmission speed may be different according to using transmission line. 

- 2) If the pulse output OFF time is set too short, count errors by connected counters, PLCs (Programmable Logic Controllers) may occur.
