EPack Lite and EFit — entry-level thyristor power controllers, 1/2/3 phase, up to 125 A, up to 500 V
Country: United Kingdom · Model: EPack Lite / EFit
EFit is a single-phase thyristor controller up to 50 A and 500 V on a DIN rail, and EPack Lite is its bigger relative for currents up to 125 A in single-, two- and three-phase versions. Both series are intended for typical heating where advanced diagnostics and fieldbuses are not needed.

Description
Install it, connect it, and the controller works; this simplicity is valued in both series. EPack Lite is designed for constant-resistance heaters and transformer primary windings, and current and voltage measurements make it possible to generate alarms. EFit works in phase-angle and burst modes, limits current and accepts an analog and logic signal. It suits constant and variable resistance heaters, IR emitters and transformer loads. Both series meet international requirements for quality, noise immunity and emissions.
How to choose
The selection criteria are the number of phases and current. One phase up to 50 A means the EFit, a three-phase or two-phase load up to 125 A means the EPack Lite. The two-phase version is more economical for balanced loads, and the three-phase one is needed when the phases are loaded unevenly. If digital communication is also needed up to 125 A and 500 V, choose the EPack, and above 125 A the modular EPower.

FAQ
Which controller should be used for a single-phase 50 A heater?
The EFit is designed precisely for single-phase installations up to 50 A and 500 V, needs no setup and is mounted on a DIN rail.
Which phase versions does EPack Lite have?
Single-phase, two-phase for a three-phase load, and three-phase, for currents up to 125 A.
Does EFit hold power during mains dips?
Yes, it compensates voltage fluctuations by itself. If the voltage changed by 10 %, the power without compensation would change by 20 %, while EFit holds linearity better than ±2 %.
Which heaters does EFit work with?
Constant and variable resistance heaters, short-wave IR emitters and transformer loads.
