SPR10-TB... Smart Power Relay Description The SPR10-T smart power relay for DC 12 V and DC 24 V applications is a controllable solid state power relay and holds three functions in a single unit: l Solid state relay with control input l Electronic overcurrent protection l Status indication by means of LED and status output SF At a width of only 12.5 mm it provides selective protection for all DC 12 V and DC 24 V load circuits. SPR10-T is track-mountable and provides ease of installation for groups of devices with several circuits. For adjustment to the load conditions the current rating is available in fixed values of 20 A and 25 A. The benefits of SPR10-T are obvious: For remote switching and protection of loads, several discreet separate components had up to now been connected in the load circuit as a functional unit: l The coil of an electro-mechanical relay is activated over a control cable. The integral contact closes the load circuit l An additional protective element (circuit breaker or fuse) providing line or equipment protection The SPR10-T offers both functions in a single device. Your benefits The integral power electronics offers a wear-free switching function, unsusceptible to shock, vibration and dust. l Compared to electro-mechanical relays, it requires only a fraction of the closed current and switching current. This is paramount for battery-buffered load circuits which have to remain activated even with the generator turned off. l The extremely low current consumption of typically 4 mA in the OFF condition is an absolute must in battery-buffered applications. l The device offers visual status indication of the load condition (load is OFF: LED is off; load activated: green LED lighted; load disconnected due to overload or short circuit: red LED lighted). l A status output for the group fault indication »SF« provides status information on the condition of the load circuit. l For direct rail mounting l Ease of wiring via entry line busbars LINE+ and 0 V, signal busbars and jumpers. equipment uptime through clear failure detection and stable power supply l Space savings through a combination of solid state relay, overcurrent protection and signalling in a single device l Reduces downtimes through quick fault resolution l Makes planning easier through a wide input voltage range from DC 9...DC 32 V
