You really don’t need to pay the best part of $1000 just to get a power supply that can charge a battery, switch over to the battery if the AC fails and trigger an alarm if the battery is getting low.
If you are experiencing difficulties with programming the MEAN WELL RPB-1600 and RCB-1600 series battery chargers, it could be due to a programmer software update.
You can easily request approval documentation, and compliance certificates for your MEAN WELL power supply by completing the Approval Document Request Form.
