New from Aerco is a cubic version of the SPPR (Smart Power Protection Relay) from E-T-A that provides switching, protection and monitoring in a single device for all 12V and 24V supplies and is a powerful alternative to electromechanical DC relays and fuses.The SPPR Type E-1048-8C is a 7-pin cubic relay with a similar specification to the in-line version announced earlier this year but is designed for applications such as automotive power relay sockets where the system architecture is more suited to the cubic shape.
Measuring 30mm x 30mm x 40mm high excluding terminals and requiring a control current of less than 10mA with an off-load current consumption of less than 1mA, the E-1048-8C is ideal for battery-buffered on-board electrical systems providing essential information such as LED and status outputs for control or group fault signals in the event of over-current or wire breakage in the load circuit.A full-feature version also provides a 0-5V analogue output proportional to the load current that can be easily incorporated into the power management of the overall system.
