Questions & answers
Know before you buy
Quick answers about the PLN-24CH12, and how it compares.
What is the Bosch PLN-24CH12?
The Bosch PLN-24CH12 is an EN 54-4-certified, 24 V DC battery charger for public address and voice alarm systems. It charges lead-acid backup batteries while supplying DC power to connected equipment.
What type of battery does the PLN-24CH12 support?
It supports a 24 V lead-acid battery bank. The battery bank capacity depends on the connected load and the required backup time.
How many DC power outputs does the PLN-24CH12 have?
It has nine DC outputs in total: six main outputs rated at 40 A each and three auxiliary outputs rated at 5 A each. The combined backup current across all nine outputs is limited to 150 A.
What is the difference between the 12 A and 150 A ratings?
12 A is the maximum current the charger supplies to the batteries and connected equipment combined. 150 A is the maximum total current the batteries can deliver through the unit’s outputs during backup operation.
Can the PLN-24CH12 report faults to another system?
Yes. It has three voltage-free fault relay outputs for mains failure, battery faults and charger output voltage faults. Front-panel LEDs also show the status of these conditions.
Can I order the PLN-24CH12 for an existing PLENA system?
Contact ESCO with your equipment models, DC load and required backup time. The team can help confirm whether the PLN-24CH12 fits your system and prepare a quotation.
