The ETT-1 is a step controller designed for switching a single electrical load ON/OFF and for doubling the output range of the EFM power controllers.
The ETT-1 is engineered to reduce the required size EFM power controller. The ETT-1 is controlled from an analogue signal from a temperature controller like the EFRP-31, which makes it possible to modulate double the power of the EFM power controller.
The ETT-1 makes a linearisation of the output to the power controller, such that the EFM power controller matches exactly to the gaps in the steps created by the ETT-1. |
