Overview

Additional wireless power monitor, single phase(EN-P) is a meter that reads data from current clamps and sends back to the Ethernet wireless receiver (EN112). It is a low cost solution and suitable for office and industrial monitoring applications. EN-P has one input to attach Current Sensor (CT5 – CT3000) supporting readings from devices up to 3000A. It communicates with the controller through the Wireless communications (RF 433MHz ISM band). It comes in a small enclosure and can be mounted on a wall. Simple to Install and easy to configure.

• Suitable for residential, commercial and industrial monitoring purposes.

• Manufactured to comply with IEC 60687/61036/61268 and IEC 62053-21/62053-22/62053-23.

• Single receiver can handle multiple transmitters.

• Plug and play. Easy to install on site.

• Wireless, low power operation.

Features

• Highly accurate design

• Manufactured to comply with international standards IEC 60687/61036/61268 and IEC 62053-21/62053-22/62053-23

• Connects with controller on 433 MHz Band

• Encrypted communications for secure operation

• Good range

Hardware architecture

Figure 1: Hardware Architecture

Wireless power monitor, single phase is built of a processor and RF transceiver to communicate with the controller. This device is responsible for taking the readings from Current Clamps and send readings to the controller via RF link. Frequency off the link is 433MHz. It transmits reading to the receiver (EN112) every 5 minutes

Pairing Transmitter With a Ethernet Receiver– Photograph

In order to pair each transmitter (EN-P) with the receiver (EN112) press the pairing mode button at the back of the receiver (EN112). During pairing mode the radio activity and server activity LEDs start flashing for about one minute. While receiver is in pairing mode connect the battery in the transmitter and wait so that it pairs with the receiver. Once it pairs you will see the radio activity and server activity LEDs stop flashing.

You need to repeat the above step each time if you have multiple transmitters (EN-P).
