EPack™ compact SCR power controllers-1PH -2PH -3PH

Efficient Power Control for Electrical Heating Applications

EPack-1PH compact SCR power controllers now available with EtherCAT communication

Designed for fast integration and optimum efficiency


OEMs and system integrators need to be able to react quickly to customer needs while maximizing resources. Whether replacing an existing product or designing a new process, the design of the EPack™ SCR (Silicon Controlled Rectifier) power controller has been carefully considered for fast and easy panel installation, commissioning and integration into wider systems, lowering equipment costs, and manufacturing times for you and your customers.

End Users continually need to improve operational efficiency and productivity. EPack power controller range can deliver real savings, significantly reducing your energy costs. Get the best from your operations; quick and easy to install, integrate and commission. A compact size doesn’t compromise powerful and versatile features that minimize costs and improve productivity and quality.

EPack 3-PH power controller is the ideal solution for the control of all kinds of loads. The control of each phase ensures accurate control, even if the loads are unbalanced). The currents and voltage measures also allow a high level of diagnostics, which can be used for alarm management as well as monitoring (impedance, energy counter, reactive power).

EPack 2-PH controller is the latest generation of power controllers designed to be a cost effective solution for the control of 3 phase loads. The 2 leg control is particularly adapted to the control of balanced loads, directly, or through transformers. Burst firing avoids generation of harmonics and reduces the consumption of reactive power.

EPack 1-PH SCR controllers are designed to carry currents from 1 to 125 amps, with operating voltage between 100 and 500 Volts

The scalability and configurability of EPack power controller range fits with the requirements of each application. A wide range of alarms can quickly identify a controller detected fault which reduces downtime.
