Two-stage deep discharge protection (TSD 40)

Two-stage deep discharge protection for optimum protection of your batteries.

The remotely controllable TSD 40 deep discharge protection protects the battery(ies) from damage due to deep discharge. Conventional devices switch off connected loads in one go. With the two-stage deep discharge protection, you can continue to operate important or safety-relevant consumers, while luxury consumers are switched off in a first step when the battery voltage drops. An acoustic alarm warns of the impending shutdown. Reconnection takes place automatically at 12.5/25V. With the setting “13 V” an energy management can be realized, e.g. an additional cooling box, a heating carpet or a hot water boiler can be activated as soon as the alternator is running or a solar panel generates enough energy. With the remote control panel FB-TSA the two outputs can be switched on remotely and in case of emergency they can be switched on again for a short period of time.
