Switch all your high currents or signals with this easy to use, dual relay. The extremely power efficient design ensures very long operation times even on very small battery capacities. Switch high powers with extremely little!
- Dual relay, can be used with the 123\SmartBMS to switch loads and/or chargers.
- Extremely power efficient, consumes less than 0.5mA (!) when both relays are active.
- High noise immunity. Can be used in industrial environments.
- One product fits all, can be used on 12V, 24V and 48V battery packs.
- Each relay can switch 120A @ 12V, 120A@24V or 60A@48V.
- Simple interface. Just connect the battery pack + and – to the module and a wire from the signal relay on the OUT board to the 123SmartRelay to switch the relay on/off like a normal relay.
The maximum switching current is 120A @ 12V, 120A @ 24V and 60A @ 48V.
The complete 123SmartRelay consumes less than 0.5mA when both relays are active. One of industrials lowest current consumptions for power relays.
Yes, the SmartRelay is a perfect companion and it will be functional in no time.
First make sure the SmartRelay is powered by your battery pack by connecting the – of the pack to pin 1 of the SmartRelay and the + of the pack to pin 4 of the SmartRelay connector.
Switch a load
Wire the + of your battery pack to the SmartBMS OUT board Load connector pin 2. Also add a wire from pin 3 to the SmartRelay input 1 or 2, depending on which relay you want to use of the SmartRelay block.
Switch a charger
Wire the + of your battery pack to the SmartBMS OUT board Charge connector pin 2. Also add a wire from pin 1 to the SmartRelay input 1 or 2, depending on which relay you want to use of the SmartRelay block.
In case you have multiple loads which will can consume more than 120A @ 12V, 120A @ 24V or 60A @ 48V, you can also use the second relay. It is even possible to use multiple SmartRelays!
You have two inverters of 100A, one used for cooking electric and one used for the oven.
Connect input 1 of the SmartRelay to input 2 of the SmartRelay. When relay 1 turns on, relay 2 will also turn on. Switch the power of inverter 1 with the first relay on the SmartRelay and inverter 2 with the second relay on the SmartRelay block.
Using the 123SmartRelay in harsh environments should be no problem. Integrated techniques ensure leakage voltages occuring in humid conditions will not falsely turn the relay on or off.
This is not recommended. When the SmartRelay power supply wire accidently breaks, both relays will stay in their position. Thus it is important to make sure the supply voltage cables are firmly connected.
Yes, but keep in mind that you can only switch AC voltages like the AC side of a charger. You can supply the SmartRelay from your last four or eight cells. In that case the SmartRelay only is supplied with 12V or 24V. This will not create a disbalance because the SmartRelay power consumption is negligible and lower than the self discharge of the batteries. Connect the “power supply –“ to the minus pole of the 4th last cell and the “power supply +” to the last cell +.
