From Esprit Tech:
Modelers using different radio systems can also directly benefit from Jeti SBEC 30 D EX using standalone telemetry with a JetiBox Profi and one of the R4US, R5US, R6US, R7-9-11US, R14-18US receivers for current and capacity telemetry data.
Brand new Jeti SBEC 30 D EX (2-16S) switching regulator with telemetry gives you exact data about your servos regarding your on-board radio system current (A) and power (mAh) consumption. The SBEC 30 D EX also can help you indirectly identify possible servo problems (max current increase) and give you the opportunity to resolve any issues before a possible catastrophic failure. Another advantage of having live on-board telemetry is the ability to fine tune the setup of multiple servo surfaces as out of sync servos will fight each other and increase current consumption.

Due to its flexibility, the SBEC 30 allows connection of up to two additional sensors. SBEC 30 then acts as an Expander and sends its own telemetry to the receiver together with the telemetry of connected sensors. You can connect the speedometer MSpeed for speed compensation (TEK) or any other sensor to any port (Ext1 or Ext2).
SBEC 30 D EX can be configured as a sensor of logic levels (log. 0 or log. 1). If you want to be informed whether the landing gear is properly secured, the logic inputs function is very convenient. Simply connect the limit switch as shown – between the signal wire and the ground (-) and you will know immediately whether the switch is ON or OFF.
