ARITECH FIRE FA500EN 27.6Vcc 5A - 4+1A switching power supply in CPR EN54-4 EN12101-10 certification enclosure

27.6Vcc 5A - 4+1A switching power supply in CPR EN54-4 EN12101-10 TUL 500EN certification housing

is an additional 27.6 V 5 A power supply designed to guarantee optimal autonomy for fire detection systems and smoke and heat evacuation (EFC) control systems

. It consists of a current-limited switching power supply, microcontroller supervision circuit and electronic fuses with automatic recovery. Constant monitoring of your functions and fault reporting in the event of: broken fuses — high battery charging voltage — low battery voltage — power failure and no battery recharge — disconnected battery — high battery resistance. The fault indications are displayed through the LEDs on the front panel and indicated by a clean-contact relay. The device is equipped with 1 output dedicated to charging the battery and 3 independent outputs. Protection against reverse polarity and short circuit. Temperature-compensated battery charging circuit. Electronic fuses to protect the outputs. In the event of a short circuit, at one of the outlets or to the battery, or in the case of a disconnected battery, the power supply is also able to supply current
