The first in a new generation of products for process control, E-T-A's electronic circuit breaker offers selective disconnection of load circuits attached to switched-mode power supplies.
E-T-A Circuit Breakers has launched a revolutionary machinery control product aimed at avoiding costly production line down-times.
The first in a new generation of products for process control, the electronic circuit breaker offers selective disconnection of load circuits attached to switched-mode power supplies.
The unique E-T-A ESS1 Electronic Circuit Breaker provides protection for output circuits connected to 24V DC switch-mode power supplies (SMPS).
It disconnects and provides physical isolation of the load circuit in the event of an overload or short circuit, while ESS1s in the other load circuits maintain voltages above 18V.
The ESS1 is suitable for resistive, capacitive and inductive loads.
Active current limitation characteristics offer particular protection against in-rush currents for high capacitive loads, thus minimising premature tripping.
An SMPS will drop voltage in the event of an overload or short circuit in any one of its output circuits if they are unprotected.
This would cause a break down in all load circuits, potentially giving rise to costly production line down-times.
Single series-connected circuit breakers in each load circuit would not necessarily solve the problem as they might not trip in the event of an overload.
The current-limiting action of the SMPS, and the consequent voltage drop, may prevent the rated current of the circuit breaker being reached.
The ESS1 can be manually set for 3A or 6A current ratings, and an integral on/off control button also acts as a manual re-set button.
The electronic circuit breaker features an LED indication of current displayed as a percentage.
This acts as an aid to fault finding which can otherwise be very time consuming, while a potential-free signal output provides an electronic means of signalling failure remotely.
The ESS1 plugs directly into the new DIN-rail mounting E-T-A SVS1 Integrated Modular Distribution system, which saves on costly wiring time and eases fault finding.
The SVS1 accommodates up to sixteen ESS1s mounted side-by-side, taking up just 333mm of rail width.
The power connection from the SMPS is routed automatically to the desired number of channels, each of which is protected by an ESS1.
Signalling can be easily established, either per channel, or in one of two groups.
Load and signal connection is rapid, via screwless, spring-loaded terminals.
