BAINTECH BTVCR160 BATTERY SEPARATOR UNIVERSAL AUTODETECT 12V / 14V

The BS can be used in situations where two batteries are present, for example in boats, caravans and campers. The BS can also be used as a voltage-dependent switch.

The BS is a microprocessor-controlled high-power mechanical switch. If two batteries are used the BS will ‘look’ at the voltage of the primary battery. A battery that is not being charged will (in a 100% charged condition) have a voltage of approximately 12.6 V (25.2 V). when the vehicle or a boat is started the voltage will slowly increase to the maximum charging voltage of approximately 14.4V (28.8V). Once the voltage has reached 13.2 V (26.4 V) for a minimum of five seconds the BS switch will close and the auxiliary battery will also be charged. As is usual in boats, caravans etc. all accessories are connected to the auxiliary battery. When the vehicle/boat has stopped, after a while the battery voltage drops and thus the switch opens again. This happens when the voltage reaches 12.8 V (25.6 V) or lower for a minimum of 60 seconds. Therefore the primary battery always remains 100°/o charged.

The Battery Separator has a second unique function. If in your application you have a battery charger connected to your auxiliary battery (often the case in boats and campers), once the voltage of the auxiliary battery exceeds 13.2 V (26.4 V) for a minimum of 5 seconds the auxiliary battery is also charged. This is a particular advantage if you remain stationary for a long period. In this case your primary battery also remains in optimum condition and once the charger is removed the switch will open if the voltage drops below 12.8 V (25.6 V) for a minimum of 60 seconds.

If you wish to make use of the start help option the battery separator has yet another connection. If you connect the start help terminal (Status) via the start switch to the plus terminal, the separator will also switch in the auxiliary battery during starting. instead of the start switch an optional remote control panel can be supplied.

In some vehicles it is desirable that power is only available via an extra terminal when the vehicle is operating. The BS is also very easy to use in this situation by connecting one terminal (A1 or A2) to the primary battery and the other terminal (A1 or A2) to your accessories. If the battery is now charged the battery voltage will quickly rise above 13.2 V (26.4 V) and the switch will close and the accessories will be powered.

All our battery separators have a unique safety system for the auxiliary battery and the accessories. If the generator voltage regulator becomes defective, the charging voltage can rise well above the allowable battery voltage. This can/will damage the battery and the attached accessories. However the BS will immediately open the switch and prevent this unnecessary damage from occurring!

TERMINAL CONTACTS
  A1 Main/primary battery plus terminal.
  A2 Auxiliary battery plus terminal or, if used as a voltage-dependent switch, the accessory terminal.
  Status 3 modes 1 – Contact on plus, relay closed.
      2 – No power on this pin, normal operation (voltage-dependent).
      3 – Contact on minus, relay remains closed.
  LED LED connection for the remote reading of the status of the relay (on or off).
  Min Earth or negative terminal. TAKE CARE! This must always be connected via a fuse of 3A, directly on the battery minus.
