EPack relaunch
Schneider Electric 2- Industrial – Eurotherm – 22/04/23
●1. Reduce your equipment costs
Schneider Electric 3- Industrial – Eurotherm – 22/04/23
EPack - What is it?
A new range of power controllers
1 phase products for the moment
Complement range to Epower
Low to middle current ratings (16A to 125A)
Advanced product (levels 1 and 2)

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
