All-motor separator coupling - Osculati

OSCULATI Separator Coupler - 12V/24V - 140A

Automatic recharging of your auxiliary battery in a converted van

Make the most of your van's energy with the OSCULATI 12V/24V splitter coupler. Automatically recharge your auxiliary battery with ease and travel without energy constraints.

Why choose this separator coupler for your van?

• Automatic dual voltage: operates on 12V and 24V without adjustment.
• Advanced compatibility: works with batteries of different makes and amperages (e.g. 80Ah starter and 120Ah auxiliary), with no restrictions on Euro 6 engines.
• Intelligent charging: automatically couples your auxiliary battery when the engine battery is charged, and protects it from discharging.
• High capacity: supports 140A continuous and 160A peak.
• No consumption when stationary: does not drain your engine battery when the vehicle is switched off.
• Advanced control (optional): allows manual control via an ignition cable, perfect for EURO 6 vehicles.

How does it work?

You start your van → The coupler detects that your engine battery is fully charged and activates the charging of your auxiliary battery.

You switch off the ignition → As soon as the engine battery voltage drops, the coupler disconnects the auxiliary battery to avoid any unnecessary discharge.

Technical specifications

• Operating voltage: 12V / 24V (automatic detection)
• Coupling thresholds: 13.7V (12V) / 27V (24V)
• Disconnection thresholds: 12.8V (12V) / 25.2V (24V)
• Maximum current: 140A continuous / 160A peak
• Consumption at standstill: 0A (no energy loss)
• Installation: automatic or with ignition cable control
• Compatibility: All engines, including EURO 6

Installation and connections

• Connection of the red cable on a Euro 6 engine: this cable must be connected to a + after contact, i.e. a live cable only when the engine is running.
• Use of the +APC on an old engine: it can be used without any problem, and is recommended if the batteries have a different amperage.

FAQ - Answers to your questions

Can two batteries of different capacities be connected?

Yes, there is no amperage limit for the auxiliary and starter batteries on a Euro 6 engine.

Is it possible to connect a 24V battery pack to a 12V engine battery?

No, there is no system for charging a 24V battery from a 12V alternator.

How do I connect the red cable loop to a Euro 6 engine?

The red loop is connected to a + after contact (live cable only when the engine is running).

does 160A correspond to the power of the alternator or starter battery?

160A corresponds to the maximum current supported by the coupler, with no direct link to the alternator or battery.

What happens when the alternator stops?

The coupler automatically separates the batteries once the charge is complete, avoiding any unnecessary discharge.

Is it useful to connect the +APC to an old engine?

Yes, it's even recommended if the batteries have different capacities.

What are the recommended cable cross-sections?

We recommend that you consult our detailed guide to connecting a separator coupler.

Does the coupler pose a risk to my alternator?

No, the alternator is designed to recharge the engine and auxiliary batteries, provided it is correctly sized.

Never leave your auxiliary battery flat on a road trip again!
