Reconnecting a discharged string back to the bus can be time consuming and expensive. And when done incorrectly, the huge in-rush of current can create dangerous and destructive arcs. The Alber RM-650 Recharge Module is the first device that lets you safely reconnect a 48 volt discharged string to the power bus so the existing on-line charger can be used for the recharge.

 

The RM-650 incorporates a manual or automatic current limiting circuit to facilitate the reconnection of the discharged battery string. The unit applies a resistance across a disconnect switch and limits current to 700 amps. Typical maximum current is 650 amps. When the battery voltage is close to the bus voltage (within approx. 0.5 volts), the string can be safely connected back to the bus.

 

Why You'll Want the RM-650

With the RM-650, you don't need to temporarily connect a large and expensive charger to the discharged string. The RM-650 reduces the risk of high-current draw when reconnecting a battery to the power bus, and features easy-to-read indicators for current, voltage, and process status. The module is protected against overcurrent and overvoltage, and has front panel terminals for easy voltage and current measurement. It's AC powered, easy to use in shop or field, and portable, with wheels for easy moving. No calibration is required.
