E-T-A Introduces Smart Power Relay for the Transportation Industry
An electronic alternative to standard automotive relays
Chicago, IL, February 2006 - E-T-A Circuit Breakers announces the E-1048-8D (E-1048 Dice) Smart Power Relay, a remotely controllable electronic load disconnecting relay matching standard four pin automotive relay sockets. The E-1048 Dice is a direct replacement of standard protection concepts and uses an electromechanical relay in combination with a blade fuse to provide electronic overcurrent protection in a single compact unit. This extension of the E-T-A Smart Power Relay product line not only saves time and space but also increases reliability and provides unprecedented load protection.
Applications
The E-1048 Dice, containing integral power electronics, is best utilized in shock and vibration applications within the transportation industry because of its wear resistant switching function. It is also suitable in applications where contact deterioration can occur due to frequent switching of inductive loads in road, rail and marine vehicles.
To meet the needs of rugged applications, the E-1048 is designed to operate at extreme ambient temperatures of -40ºC to +85ºC (-40ºF to 185ºF) without the need for derating. Additionally, it requires only a fraction of the control power needed by electromechanical relays (approximately 5 mA) and has extremely low current consumption (less than 1mA). Both fractional control power and low current consumption make the E-1048 Dice ideally suited for battery-buffered on-board electrical systems.
Specifications
E-T-A's new 30x30x30mm, dice-shaped E-1048-8D relay is available in DC 12/24 V and in nine current ratings in two basic versions. The "entry" version offers standard electronic relay functionality and an additional short circuit proof switching output. The "entry protect" version adds additional overload protection to the standard electronic relay - providing prompt disconnection in the event of an overload or short circuit.
The E-1048 Dice is based on a power MOSFET transistor with high side power switching that meets EN 61000-6-2 requirements for noise immunity and is available from 1A through 25A. For loads exceeding 25A, it is possible to connect several units of identical current rating in parallel. When doing so, uniform power distribution between units must be ensured by symmetrical design of the supply cables.
Price and Availability
E-T-A's Type E-1048-8D Smart Power Relay is available from stock and is priced at around $17.00 in volume. For more information on the E-1048-8D or any of E-T-A's solid state remote power controllers (SSRPC's), call E-T-A at 1-800-462-9979 or visit www.E-T-A.com.
