Schneider Electric 5- Industrial – Eurotherm – 22/04/23

Hardware variants

EPack is fully configurable/upgradable except :

-The mechanics (32A, 63A, 100A or 125A)-The voltage of the auxiliary voltage

(24V AC/DC or 100-500V AC)

These options require a different build of the product and can’t be changed in the field.

32A 63A

100A 125A

Schneider Electric 6- Industrial – Eurotherm – 22/04/23

The product is equipped with two supplies :oPower > thyristoroAuxiliary > comms and display

Why? We cannot use power voltage for configuration Potential at the output of the product at 0% of setpoint => Safety issues

To run comms even in case of power fault Can provide diagnostics in every condition

To be able to configure the product without dangerous voltage Configuration can be made with presence of 24V only

Supplies

Schneider Electric 7- Industrial – Eurotherm – 22/04/23

All firing modes are available in standard

Burst modes Fixed burst (100 periods by default, adjustable from 25 to 1000) Variable burst (16 periods by default, adjustable from 1 to 100) Intelligent half cycle

Phase angleProgressive start-up (phase angle ramp)Delay triggering (First firing delay)Switch phase angle/ burst

Firing modes

Schneider Electric 8- Industrial – Eurotherm – 22/04/23

EPack is able to deliver the power based on the following controls

V² control Suitable for pure resistive loads (constant resistance)

V² control with current limit (V2CL) Suitable for primaries of transformers with pure resistive loads

I² control Suitable for HTCL loads / bushing

True Power control Suitable whose resistance changes according to age or temperature (TTDL)

Control modes

Schneider Electric 10- Industrial – Eurotherm – 22/04/23

1. Complete oder code – 19 fields Defines completely the product : fit for purpose No adjustment in case of replacement

2. Quick code – 11 fields Hardware and software options defined by order code Configuration through set of questions More than 80% of applications are covered

3. Itools Same as quick code for HW and SW definition Access to all parameters of the product / with help available Saving and cloning capabilities

3 configuration methods

Schneider Electric 11- Industrial – Eurotherm – 22/04/23

Protocol Modbus TCP for the moment Other protocols to come…

Connection Direct Through a switch Daisy chain

Cable Straight Cross

Used for Itools configuration Fieldbus connection

Dual Ethernet port with integrated switch

Comms

Schneider Electric 12- Industrial – Eurotherm – 22/04/23

What is it?Zero configuration networking (zeroconf) is a set of techniques that

automatically creates a usable Internet Protocol (IP) network without manual operator intervention or special configuration servers

How does it work?It allocates dynamically the IP addresses to the slaves if no address is

affected by DHCP server (Auto-IP)

What does it result in? A plug a play Ethernet connection!

Zero conf protocol

Schneider Electric 13- Industrial – Eurotherm – 22/04/23

No internal fuse

Fusing methods depends on the option

Without fusefor loads generating high surge current (typically SWIR)Requires protection against overloads and short circuit

High speed fuseProtect thyristor against short circuitRequires additional line protection
