Eurotherm EPack 1PH Compact SCR Power Controller
Designed for fast integration and optimum efficiency
Eurotherm EPack is a compact fully featured power controller from Eurotherm, combining a high level of functionality and configurability with simplicity of setup and operation. The combination of advanced configurable firing modes allows close matching to load characteristics for maximum process efficiency. EPack is highly configurable and may be adapted for current and future needs using a software key to purchase additional functionality when needed.
Ratings and Physical Format
EPack power controllers are designed to carry currents from 1 to 63 amps, with operating voltage between 100 and 500Volts. It has a compact DIN rail and bulkhead mounting format in two widths depending on the current rating (16A to 32A or 40A to 63A). The units are specified for normal operation up to 40°C; h owever operation at 50°C is possible with current de-rating. There are two options for auxiliary power supply, 24V ac/dc or 100-500Vac.
Clear visualisation of all operating and configuration information is available on the clear, high definition 1.5″ TFT display. This includes alarm indication as well as process and operating data such as nominal current, load voltage and energy usage. Should a control system fault occur, clear messages allow the precise origin of the problem to be determined, reducing down-time.
Eurotherm EPack Applications
Plastic – Extrusion, Injection moulding
Food and Beverage – Drying, sterilization, baking
Glass – Float manufacturing
Eurotherm EPack Communications
EPack has Ethernet communications as standard, and includes an integrated dual port switch so that units may be “daisy chained”. This allows integration with other plant equipment using standard Ethernet protocols such as Modbus/TCP, allowing connection to process and temperature controllers, Programmable Logic Controllers and SCADA/Supervisory systems. Full diagnostic and operational data is available for use by higher level systems and to allow process improvements. Plug and play Ethernet connection is provided via “zero configuration” protocol.
Analogue communication for power setpoints is fully supported,
using standard current and voltage inputs to the EPack unit.
Eurotherm EPack Configuration
EPack is fully software configurable, with all options and advanced functions available when needed. Software modules may be purchased when required by use of a software key so that existing units may be adapted to changing needs over time. The instrument order code allows pre-configured units to be delivered ready for use, or alternatively a “Quick Start Code” using integrated HMI may be used to quickly configure for use. When a deeper level of configuration is required, Invensys Eurotherm iTools provides comprehensive access to all functions with context sensitive help.
