EVERSECU 24V 5Amp UPS Power Supply For Fire Alarm System Metal Boxed Cabinet Regulated Power Supply Unit with Backup Battery Link for Fire Damper, Smoke Vent, Indicator, Fireproof Gates
General Protection: Individual PTC (Positive Temperature Coefficient) Fuse and LED indicator on each output, when problem occurs, only affect the individual output, other outputs still working;
DC 24V 5A power supply unit, Status indicator LEDs (for AC, batteries), 2 fault signal outputs via mains failure relay and general fault relay, Two-stage battery charging, normal charging and floating charge, Supervised battery circuit resistance monitoring, Battery reverse polarity protection, Battery deep discharge protection (Automatic low voltage disconnection system), Battery overcharge protection, Low battery voltage indication
Short Circuit Protection: When short circuit occurs, Individual PTC Fuse will cut off the circuit and when breakdown removed, PTC fuse will automatically be restoring circuit;
High voltage protection: When high voltage occurs, the surge protection will be hit through to protect the connected device;
Over Current protection: When over current occurs, the power supply will automatically switch to self-protection status, when it is removed, then it will return to normal state;
