Integrated web server

EPPE C8 has an integrated web server which allows users to access relevant measurement data from any PC with any Internet browser. There is no need to install special software.

Dual-processor system

Thanks to an additional interface processor, EPPE C8 provides a wide range of communication options. This innovative technology makes long data transmission times a thing of the past and enables EPPE C8 to be easily integrated in any network.

IEC 61850 || Modbus

EPPE C8 can use a range of data protocols, including Modbus and IEC 61850.
These communications services run in parallel, enabling data to be exchanged quickly between different systems.

Energy meter

EPPE C8 features an integrated energy meter with an accuracy class of <0.2 which can be used to further optimise energy consumption. The energy consumption of installations can be monitored online and trend analysis can be carried out over long periods. Active, reactive and apparent energy can be recorded and analysed extremely precisely.

Data memory

With 2 GB of flash memory, the EPPE C8 power quality analyser stands out from the crowd. This large memory capacity allows measurement quantities to be recorded at very high resolutions for long periods of time, even when there is no permanent data connection to a mass data storage medium (server).

Another advantage of the flash data memory is that measurement data is not lost during interruptions to the power supply or when the device is switched off - the data is completely safe, even without additional battery support.

Inputs and outputs

Analog inputs
EPPE C8 features 4 current and 4 voltage inputs which can measure up to 40 A (max. 100 A for 3 seconds) and 600 V.

Binary inputs and outputs
The device has 12 binary inputs and 8 relay outputs. The binary inputs are divided into 3 groups, each of which has a common reference point.

Time synchronisation

1. NTP (Network Time Protocol)
2. GPS
3. DCF77
4. KoCoS synchronisation bus

The KoCoS synchronisation bus is used for synchronising the time of a number of EPPE C8 devices and for passing on trigger information. The cross-triggering function can also be used to start fault recordings absolutely simultaneously on a number of EPPE systems at once.

Installation

EPPE C8 is designed for panel mounting. A bracket system for DIN-rail mounting is available as an optional extra if required.
The standard delivery package includes a wide-range power supply unit for flexible powering. The devices can also be equipped with a variety of DC power supply units for other applications.
