EPack compact SCR power controller

Description

EPack is a compact power controller from Eurotherm that combines extreme functionality with simple operation and setup. Modern, freely configurable operating modes enable optimal adaptation to the load characteristics and thus ensure maximum process efficiency. EPack can be flexibly adjusted and additional functions and extensions can be activated using a software key if required.

Nominal values ​​and design format

EPack power controllers are designed for load currents of 1 to 125 amps, with an operating voltage of 100 to 500 V. The compact design is suitable for DIN rail or wall mounting and is available in two widths depending on the load current range (16 A to 32 A or 40 A to 100 A or 125A). The device is designed for temperatures up to 45 °C during normal operation. There are optional two auxiliary voltages with either 24 VAC/DC or 100-500 VAC.

The clear, high-resolution 1.5″ TFT display provides all the necessary information about operation and configuration. This includes alarm display as well as process and operating data, such as: B. nominal load, load voltage and energy consumption. If an error occurs, a plain text message appears, which guarantees precise localization of the error and quick resolution. This reduces downtime to a minimum.

Applications :

• Plastic – extrusion, injection molding
• Food and beverages – drying, sterilization, baking
• Glass – floating process
• Infrared heaters – especially for short-wave IR radiators

communication

The EPack power controller has Ethernet communication and a dual-port switch as standard, so that several devices can be connected in series (daisy chained). With standard Ethernet protocols such as Modbus/TCP, integration into an existing system and communication with other devices such as temperature and process controllers, PLCs, SCADA and monitoring systems is simplified.

Higher-level systems can access diagnostics and operating parameters and thus optimize the overall process. The “plug and play” Ethernet connection is provided via the “zero configuration” protocol.
With standard voltage and current inputs, the EPack supports analog communication for power setpoints.

configuration

EPack features and options are fully software configurable. The software modules can be ordered as required and subsequently implemented using a software key. This means that devices that are already in use can be adapted to increasing requirements at any time. Using the order coding, the device can be ordered directly pre-configured and ready for use. Alternatively, the software configuration can be done later using the “Quick Start Code” on the device. For more complex configurations, the Invensys Eurotherm software iTools offers access to all functions and parameters.
